Here’s an easy guide for DIY bathroom waterproofing:

First of all, make a note of all the points in the bathroom where there is a high probability of leakage. This may include places like all the drainage line openings through the walls and floor, concealed water lines and buried PVC or GI fittings, pipe joints, wall and floor tile joints, walls near the shower area, bathroom door jambs and threshold fitting, joints adjacent to a shower tray or a bathtub and connection points of a wash basin, for example. Pay special attention to these points while doing the job to make sure they are properly sealed.

Step 1: This is a step you need to do thoroughly. Clean the walls and floor of the bathroom, removing all the dust and dirt. Then make sure the bathroom is completely dry and that there is no moisture on the walls and floors.

Step 2: Find a good quality DIY bathroom waterproofing kit. If you are clueless about which one to buy, do some research online and visit several hardware stores. An ideal DIY bathroom waterproofing kit should consist of:

• Tanking membrane
• Waterproofing acrylic primer
• A tube of neutral core silicone sealer
• Edging tape
• Gloves
• Brush

Step 3: Take the tube of silicon sealer included in the DIY bathroom waterproofing kit and run a bead along all the internal corners of the wall as well as the floor and give a proper finishing to it with your fingers. Do not forget to wear gloves while doing this.

Step 4: Using the paintbrush, apply a liberal coat of the tanking membrane to all the internal corners. Make sure you paint on the either side of the membrane and make the breadth of the patch approximately 200mm.

Step 5: Place edging tape along the length of each corner and smooth it down to bed it into the wet membrane. Ensure the tapes overlap by at least 150mm.

Step 6: Apply a second coat of membrane over the clog drains, around the taps and over every other penetration through the wall or floor.

Step 7: Apply a coat of waterproofing acrylic primer all over the surface of the bathroom including the walls and floor.

Step 8: Apply another coat of the acrylic primer in a 90 degree direction to the previous coat.

Step 9: Let it dry for at least 24 hours before doing any further work.
After these steps, there are further precautions you can take to avoid bathroom leakage.

Apart from waterproofing, you should also make sure the slope of the bathroom floor is directed towards the drain in order to avoid water accumulation elsewhere, as this can also be a major cause for water leakage.

Also, select a waterproof paint for the ceiling and walls if you plan to paint the bathroom and get a vent or fan installed to eliminate moist air from the bathroom. Excessive steam can lead to moisture accumulating on the walls and eventually seeping through the walls and leading to algae formation.

Mengapa Perlu Guna Agen Pelekat Konkrit/Simen.

Concrete bonding agents: why you need to use them, and which to choose.

When a concrete floor surface becomes damaged there is usually the choice of either demolishing the floor and starting again, or resurfacing the existing concrete. Removing the entire floor and re-pouring is costly, both financially and in terms of time. It’s also wasteful if the floor is still structurally sound. One solution is to add fresh concrete on top of the old surface.

Why you need to use a concrete bonding agent

The cement within a concrete mix doesn’t contain any natural bonding agents – so when fresh concrete is added on top of an existing layer of concrete, the two won’t join together. Once cured, the new concrete will simply sit on top as a separate layer. This will not produce a strong, serviceable floor.
A bonding agent (bonding adhesive) needs to be painted onto the existing concrete first to ensure that the fresh concrete will successfully adhere.
This is also true of floor repairs, if concrete is used to fill gaps caused by damage. The new won’t adhere to the old without the help of a bonding adhesive.

Surface preparation for a bonding agent

If an existing concrete surface has laitance (a dusty layer of cement and fine aggregates), or has been contaminated with spillages such as oil or grease, then the bonding agent won’t work well. Surface preparation is absolutely vital to ensure that the bonding agent is applied to a sound concrete surface. This involves intensive cleaning, usually by pressure washing (using floor cleaning solvent), or vacuum shot blasting.
If there are spillages which have seeped into the floor’s surface, grinding or milling may be necessary to remove the top few millimetres of the existing floor’s surface to get down to clean concrete.

Which bonding agent to choose?

The choice depends on where the bonding agent will be used, and the likely use of the final floor surface.

• Roc Latex is a synthetic resin bonding agent for concrete and mortar. Applied to existing surfaces, it will ensure that new concrete will adhere well without cracking. Roc Latex also improves the durability of mortar.

          Latex is supplied is a synthetic resin liquid which needs to be mixed with water, sand
          and cement to make a slurry. This can be applied to an existing concrete surface before adding
          a screed, mortar on concrete on top while it is still sticky. It can also be used before adding a               resin surface, and for mortar and masonry joint repairs.

• Prim is a two-part epoxy resin concrete adhesive, which is mixed together on site. It is used to bond two layers of concrete together, and also acts as a moisture vapour barrier between the two layers. This epoxy concrete adhesive allows new concrete to be poured on top of old without cracking.  It also acts as a moisture barrier between the two layers.

• Placeo Cemcol is a super-strong concrete bonding adhesive, and the best choice for instances where the top surface will contain hard aggregates, or be subject to heavy traffic. It is supplied as a powder, which needs to be mixed with water on site and applied to a slab which has been drenched with water the day before. Cemcol is a concrete bonding adhesive with excellent strength. It is the ideal preparation for laying new concrete, screed or slurry on an existing concrete surface.

The bonding agents should be carefully and thoroughly applied, either with a brush, a broom or a roller – or for larger areas they can be sprayed on.

Cara Guna Gam Simen

Whether you’re filing in a crack, repairing a section of concrete, or pouring a whole new layer over an existing layer of concrete, getting the new concrete to adhere to the old layer can be difficult if you don’t follow the proper procedures. Start by cleaning the older concrete with a strong acid wash. Then, prepare a bonding slurry to ensure the new concrete adheres to the previous layer. Dampen the existing concrete, apply the bonding slurry, then add your new concrete. 

Part One of Three:

Cleaning the Old Concrete with Acid Wash

1.      Clear the area and sweep the concrete to remove large particles. Pick up any objects, move any furniture, and remove any people or pets from the area so you can clean the concrete. Use a broom to sweep away dirt and debris from the old concrete.^[1]

• If your concrete has cracks or grooves, use the bristles to sweep out and remove as much of the dirt or debris as possible.

2.      Mix 7 parts water to 1 part muriatic acid in a bucket. Muriatic acid is a strong chemical cleaner that will strip away dirt, oil, and debris. The acid will also soften the top layer of the concrete and make it ready to bond with the new concrete. Put on a face mask to avoid inhaling the fumes and pour the water into the bucket first, then add the muriatic acid and give the mixture a gentle stir.^[2]

• For example, if you add 7 cups (1,700 mL) of water, add 1 cup (240 mL) of muriatic acid to the water to create an effective cleaning solution.
• You can find muriatic acid at hardware stores and online

Warning: Muriatic acid can put off noxious fumes. Work in a well-ventilated area when you’re mixing the solution so you don’t breathe in the vapors.

3.      Pour the acid mixture over the old concrete. Pour the mixture directly from the bucket or use a plastic sprinkler can to distribute it over the old concrete. Be sure to cover all of the concrete evenly.^[3]

• If you get some of the mixture on your skin, rinse the affected area under cool water. The acid can cause dryness and a slight burning sensation if you let it sit for too long.
• Wash out the bucket or plastic sprinkler can with clean water when you’re finished applying the acid mixture.

4.      Allow the mixture to sit for 10 minutes. The acid wash should start to foam and may make a hissing sound. This is a normal part of the cleaning process. Allow the mixture to remain on the concrete for about 10 minutes so it can work to lift and remove oil and dirt.^[4]

5.      Wash the old concrete with a pressure washer. Take a pressure washer and use a back and forth sweeping motion to spray and clean the concrete. Work in sections and be sure to clean every bit of the concrete and wash off the acid mixture.^[5]

• You can rent a pressure washer from home improvement stores if you don’t own one.
• If you can’t get a pressure washer, you can use a garden hose to rinse the concrete, but it won’t be as effective at removing oil and grime.
• If you’re rinsing concrete near grass or plants, throw a handful of baking soda on the plants that come into contact the the acid mixture to neutralize it. The acid could kill the grass or plants.^[6]

Part Two of Three:

Mixing a Bonding Slurry

1.      Mix together equal parts water and white glue in a bucket. A bonding slurry will greatly increase the adhesion between pieces or layers of concrete. In a large bucket, add equal parts water and white glue and stir the mixture together.

• For example, if you add 2 cups (470 mL) of water, you need to add 2 cups (470 mL) of white glue into the bucket.
• You can use ordinary crafting glue that you can find at department or art supply stores.

2.      Put on a face mask before you add cement. Breathing in the cement dust can irritate your mucous membranes and cause respiratory problems if you inhale it. Before you add any dry cement mix, put on a face mask to prevent possible inhalation.^[7]

• Make sure the mask fits snugly over your nose and mouth.

3.      Add 2 parts of dry cement mix to 1 part of the water and glue mixture. Once you’ve mixed the glue and water together, add dry cement mix into the bucket at a ratio of 2 to 1. You want the mixture to have a consistency similar to a thick paint.^[8]

• For example, if you’ve mixed together 1⁄2 gallon (1.9 L) of water and glue, you’ll need to add 1 gallon (3.8 L) of cement mix.
• If you add too much concrete, add more water and glue to loosen the paste and make it softer.
• Use portland or mortar cement mix for the most effective bonding slurry.

4.      Stir the mixture in the bucket to create a slurry. Use a wooden spoon or a metal mixing tool to stir the mixture until it’s the right consistency. Stir along the bottom and the edges of the buckets so there aren’t any pockets of dry concrete powder.^[9]

• Add more concrete powder or water if necessary.

5.      Keep the bucket of slurry covered and cool so it lasts longer. The slurry mixture will harden faster than concrete and become unusable once it sets, so don’t allow the slurry to sit for more than 1 hour. Use it soon after you mix it together.^[10]

• Avoid keeping the bucket in the sun or it will harden faster.

Part Three of Three:

Bonding New Concrete to Old Concrete

1.      Wet the old concrete thoroughly. In order for the concrete to adhere together effectively, it cannot be dry. The concrete must be damp so the water permeates into the older concrete to help achieve a strong bond.^[11]

• Don’t soak the concrete or allow standing puddles of water to form or the concrete won’t set.

2.      Mix a new batch of concrete. Use a large bucket and add your water to the concrete mix according to the instructions on the back of the bag. Pour the water slowly and stir the mixture well. Work out any lumps that form to create an even consistency.^[12]

• Keep the concrete mixture nearby so you can apply it when you’re ready.
• Wash the tools you use to mix your concrete after you’re done so the concrete doesn’t harden on them.

3.      Brush a thin layer of the slurry mixture onto the old concrete. Before you add your new concrete, take a large brush and dip it into the bonding slurry. Brush the slurry over the damp concrete to form an even layer. Make sure all of the old concrete has a layer of slurry on top of it before you move on.^[13]

• Use a big paintbrush or any other type of large brush to apply a layer of the slurry.
• Make sure the concrete is damp before you brush the slurry mixture.

4.      Pour the new concrete on top of the old concrete. After you’ve brushed your slurry mixture onto the old concrete, you can apply the new concrete that you mixed. Dump out all of the concrete onto the old concrete and spread it out with a hand trowel or a paver to form an even layer.^[14]

• Make sure you form a layer with a consistent thickness so the concrete dries evenly and doesn’t have any bumps or waves.

5.      Allow the concrete to dry for 12 hours. After you’ve poured the new concrete and formed an even layer, allow it to sit undisturbed so it can set. Drying times can vary depending on the concrete mixture, and the temperature and humidity of the area. To be safe, let the concrete dry overnight or for 12 hours.^[15]








 

Bangsa Cina dari Penulis Cina

C&P

YE LIN SHENG pemegang PhD, Penulis buku THE CHINESE DILEMMA. Kalau tak sempat baca bukunya, baca dan sebarkanlah rumusan bukunya seperti berikut..

APA PENULIS KATA BERKENAAN CINA:

1. Pandangan ini adalah dari Ye Lin- Sheng yang berasal dari China tetapi seorang ahli perniagaan di:
- Malaysia,
- Hong Kong,
- Australia,
- Thailand,
- Singapura,
-.Britain dan
- Amerika Syarikat.

Beliau mempunyai banyak pengalaman yang melibatkan orang Cina di negara yang disenaraikan itu. Tetapi orang Cina di Malaysia lah yang paling :
- tidak bersyukur,
- kejam, serta
- mengkhianati perjanjian ataupun
- tidak mahu rujuk perlembagaan Malaysia

Dalam buku Ye Lin- Sheng The Chinese Dilemma - East West Publishing, Australia, 2003, Ye Lin- Sheng menulis:

2. Pengiktirafan orang Cina:
"Orang Cina Malaysia mendapati mereka lebih mudah untuk menerima dominasi oleh orang- orang putih kerana mereka dapat memberi pengiktirafan terhadap kehebatan orang Barat.

Tetapi Orang Cina Malaysia amat susah untuk menerima kehebatan orang Melayu kerana perasaan iri hati dan hasad dengki mereka bahawa Malaysia ini milik orang Melayu. Mana- mana orang Cina Malaysia sama sekali tidak boleh menerima tentang konsep ketuanan Melayu, mereka percaya bahawa mereka adalah lebih baik"

3. Keangkuhan orang Cina:
"Keangkuhan orang cina Malaysia telah membuatkan mereka sentiasa memandang rendah terhadap keupayaan orang Melayu, walhal ramai orang Melayu sebenarnya bekerja atau belajar lebih pandai dari kaum cina Malaysia ini.

Perkara ini sudah lama saya perhatikan, kerana saya memiliki perniagaan di Malaysia dan telah bercampur dengan orang Cina Malaysia ini. Sikap mereka suka cakap belakang dan tekan orang Melayu adalah menjadi tabiat dan budaya mereka.

Mana mana orang Cina Malaysia yang tidak menghina orang Melayu dikatakan kolot dan membelot bangsa cina"

4. Perkauman orang Cina:
"Kejayaan orang Cina Malaysia hanya tercapai jika mereka dapat menindas orang Melayu dalam masa yang sama menggunakan kudrat dan kelebihan orang Melayu.

Mereka juga tidak akan mengakui bahawa kepimpinan Melayu adalah sangat mahir, cekap serta bagus dalam pengurusan politik, ekonomi dan sosial.

Cina jarang menyifatkan kejayaan Malaysia daripada orang Melayu. Apa yang ada di minda mereka adalah semua kejayaan di Malaysia ini adalah kerana orang Cina. Sebab itu orang Cina yang asal dari China tidak suka bergaul dengan Cina Malaysia kerana sikap mereka yang ekstrim ini.

Mereka masih lagi mengamalkan ideologi komunis"

5. Penghinaan orang Cina : "Sampai hari ini, sesetengah orang Cina Malaysia masih menggunakan istilah "Menghina" terhadap orang Melayu.

Dalam dialek Cina yg tertentu, orang Melayu dipanggil dengan nama yang bermakna ‘orang hutan’ atau ‘orang liar’. Maknanya, Bangsa yang tidak Bertamadun.. Malahan orang Cina yang memeluk Islam dikatakan telah ‘masuk Melayu’.

Jarang ibu bapa Cina membenarkan anak mereka menjadi Askar atau Polis kerana anggap itu kerja kotor dan hanya Eksklusif kepada kaum Melayu sahaja.. Mereka sentiasa percaya bahawa budaya dan Tamadun Cina lebih tinggi berbanding Budaya dan Tamadun Melayu termasuklah penggunaan membersihkan diri menggunakan tisu dianggap lebih bertamadun.. Umumnya, orang Cina boleh menerima ‘Ketuanan orang Putih’ kerana menganggap tamadun dan Budaya Barat lebih bagus, tapi tidak terhadap Tamadun Melayu -Bumiputera."

6. Sikap negatif orang Cina :
"Kejayaan orang Melayu turut dipandang sinis. Ia biasanya dikaitkan dengan bantuan Kerajaan atau hak istimewa yang diberi kepada mereka.

Kebanyakan Cina Malaysia sukar menerima hakikat kejayaan Usahawan atau Syarikat2 Melayu.. di mana mereka berniaga secara jujur dan bukan seperti orang Cina berniaga. Jadi sebenarnya majoriti orang Melayu ada peniaga tulen yang jujur dan dicapai menerusi kerja keras mereka.

Sikap sebegini sebahagiannya berpunca daripada kesukaran menerima hakikat orang Melayu lebih pandai daripada mereka dan sebahagian lagi bertujuan menunjukkan pencapaian mereka sebagai lebih hebat"

7. Isu Tuan Rumah:
"Siapakah Tuan Rumah Negara Malaysia? Ia adalah orang Melayu selaku Tuan Rumah, dan orang Cina dan India sebenarnya hanya
lah sbg tetamu ataupun dipanggil menumpang kerana tiada tempat.

Orang Cina Malaysia sepatutnya berasa malu kerana telah datang secara asal untuk menjadi pekerja dan selepas diberi Kerakyatan.... Akhirnya mereka cuba hendak merampas serta menindas Tuan Rumah - Bangsa Melayu. Sudahlah mereka datang dengan jumlah yang besar dan ramai.

Jika saya: Ye Lin Sheng, penulis Buku, adalah orang Melayu, saya tidak akan membenarkan Perlembagaan dan Sosial Kontrak dicabar. Saya akan merasakan maruah dan penghormatan saya akan tercalar"

8. Orang Melayu sebenarnya sedang dijajah oleh Cina :
"Tetapi itulah keistimewaan orang Melayu, mereka adalah satu Bangsa yang bersopan santun dan kaya dengan kesabaran...

Sudahlah mereka bersusah payah Berjuang bermati- matian untuk membebaskan diri dari Jajahan Barat. Sekarang mereka perlu bersusah payah pula untuk merampas dari orang Cina yang memegang kuasa ekonomi di Tanah airnya.. Sepatutnya orang Cina yang perlu berbakti kepada orang Melayu kerana mereka sudah diberi peluang utk mendapat kerakyatan, tetapi saya selaku orang asal dari negara China berasa malu dengan sikap Bangsa saya sendiri yang tinggal di Malaysia. Tidak ada perkataan yang dapat saya berikan kerana dasar orang Cina Malaysia terlalu keras, Ekstrim serta Perkauman.

Kami sendiri orang yang tinggal di China tidak lagi menerima ideologi Komunis, tetapi orang Cina di Malaysia lebih selesa untuk mengamal. serta menyebarkan ideologi Komunis sehingga kini.. Sebenarnya jujur saya mengatakan orang Cina Malaysia sedang Menjajah Orang Melayu... Mereka seperti menganggap bahawa orang Melayu adalah musuh mereka yang nyata"
