Water-proof and Moisture-proof your walls and home

That dark, dank, musty smell that permeates your home is because moisture has infiltrated the interior walls of your home. It is likely there is mold, mildew, cracking. Damp patches on walls in bedroom or living room not only is an eyesore, but can damage the wall structure and your health. Dampness will lead to worsening of plaster, masonry, stones, tiles and also deteriorate timber work and expensive wallpapers within your home.

If not addressed, there could be structural damage, over time.

Fact is, waterproofing will not last over time, especially in humid Singapore. If the moisture and damp spots you notice is only paint-deep, just let the paint dry off. Simply scrape off the old layer paint, sand the wall, and repaint.

On the other hand, if it is the external walls -which are always exposed to the wrath of our hot or rainy weather- that is causing the seepage, this continuous exposure to rainwater and heat will lead to cracks in the plaster, making the walls damp. If not corrected, this will eventually ruin the interior of your home as well.

Thankfully, there are effective corrective and preventive measures to avoid or at least control the moisture into the interiors of your home. However, these treatments are only effective if we get to the root cause of the matter - where the moisture originates from. If there is a chance of it recurring, then the source of the moisture should be tracked and plugged.

Applying the wrong treatment though, may cause more damage and expenditure.
If you are thinking of simply sealing the walls with tiles or any other material, don’t. It is not a long term solution as your walls need to breathe. When you first notice damp/water spots on the wall, try to identity the cause of it.
Check whether the cause for the seepage is because of a leaking water tank or a broken plumbing

It is caused by water seeping through the walls. You will usually note damp patches on walls that have bathroom or sunken portions on other side of walls. Roofs, parapets and any construction joints are possible source of rain water penetrations. Prolonged rain with high intensity and poor materials used in structure can cause water seepage even in vertical walls. Leaking drain pipe or fittings are other prime sources of water seepage.

In case a gap exists between the walls of your home and your neighbor, or you share a wall with your neighbor who has had poor wall waterproofing done, this would also cause water to seep through to your side. Water seepage happens when the outer walls are not plastered properly or due to use of poor-quality plastering materials. You may then have to approach your neighbor to inform them of the water seepage so they can treat it. Coatings and protective plasters can be done at damp areas.

Corrective Measures:

If the problem is of a small scale, it can be easily rectified with a few simple steps
Step 1: Sand walls
Sanding the wall with a high-grade sand paper is important to remove mildew and mold in damp areas. Good quality sand paper will help in sanding the walls effectively. This will also ensure that the water proofing remains effective in the long run.

Step 2: Crack Sealers
Exposed areas that have developed cracks can also attract moisture. Before waterproofing, it is important to clean from all the surfaces loose paint dust and grease. Sealers are specialized chemicals that you can apply to wood or masonry interior walls just as you would apply a coat of paint. However, unlike paint, a sealer fills in the minute gaps and pores in a material, making the material watertight and less likely to become inundated with water
After washing the wall, it would be good to tackle all the cracks and treat them properly. Crack seals can be used to fill them up. Bigger cracks and damaged areas can be repaired, using polymer modified cement mortars. After the filling is done, it should be allowed to dry for about four to six hours.
Step 3: Adhesives and compounds
Some of the modern waterproofing methods that can help water proof walls are silicon-based water repellents, polymerised bitumen, a polymer-based waterproofing compound that is ready to use, waterproofing adhesive, injection grouting for cracks, and silicon sealants. There are also waterproofing membrane-forming coating, which are effective as well.
Step 4: Good-quality paints:
When the paint used for the walls is of inferior quality, moisture tends to seep through the concrete, thereby damaging the walls. Modern-day high-quality paints are resistant to water and contain silicon that offers the walls extra strength.

Corrective Measures:

Keep your house at a constant temperature throughout. This will prevent sudden rises and dips in temperature which leads to condensation. There are also smart home devices to monitor the temperature throughout your home. The humidity in Singapore is something we have to content with. You may decide to shut your windows and doors, however you will not get air circulation. As we all know, when humid air comes into contact with cold surfaces, it condenses and cools droplets of water.

Install exhaust fans for proper ventilation: Place exhaust fans in the kitchen and bathroom. This will ensure proper ventilation. Do check that the washing machines and tumble dryers are vented correctly. Also, use windows for proper ventilation. We can reduce humidity in the home by improving ventilation and insulation. Additionally, we should use water repellent chemicals on wall plaster to protect walls by providing positive waterproofing. There are chemicals available that can be simply sprayed even on existing plaster.

Limit the production of moisture: If you choose to dry laundry indoors, this creates moisture within the home. Choose to dry your clothes outdoors instead.

If you do not have another option to drying clothes inside your home, dehumidifiers will remove the excess amount of moisture form the air. Overall, your home will become more comfortable space. Moisture absorbers are perfect for cupboards and tight spaces.
LWhile Cooking: Pans and cookers create a considerable amount of steam. Covering pans with a lid will prevent the amount of steam that will go out. Also, replace the filter on your cooker hood regularly.

After you have taken these corrective and preventive steps, but still have not seen an improvement, or you have a problem of a larger scale, call in a certified and experience specialist from iimafix. We will be able to assess and isolate the cause, after which we will rectify the problem with up to 12 months warranty.
