Waterproofing is one of the most critical steps to protect your home from long-term water damage, seepage, and cracks. Whether you're dealing with monsoon leakage or general wear and tear, a proper waterproofing method ensures durability and peace of mind. In this blog, we’ll reveal five essential secrets behind effective waterproofing Method and how you can implement them easily using the DIY method.

Secret 1: Clean Surface = Strong Waterproofing Bond

One of the biggest mistakes in waterproofing is ignoring the cleaning process. Waterproofing chemicals need a dust-free and solid surface to bond effectively. If the surface has loose particles, algae, or flaky cement, the coating will eventually peel off.

DIY Tip:
Use a paint scraper or angle grinder to remove old cement flakes. For best results, clean the surface thoroughly with a high-pressure washer to ensure no dust or grime is left behind.

Secret 2: Open and Treat All Visible Cracks Visit – How to Fix Cracks

Cracks are the number one reason behind water leakage. Simply applying a waterproofing layer without treating cracks is not effective. You must widen them slightly and then seal them with the proper chemical and reinforcement.

DIY Tip:
Use an angle grinder to open hairline cracks into V-grooves. Then, apply Waterseal PSv PREMIX over a PPC Crack Mat to cover and seal it firmly. This ensures long-term flexibility and strength.

Secret 3: Apply Waterproofing in Multiple Coats

A strong foundation is created with a base coat prepared using:

1 part PSv + 2 parts water +1 part  White cement OR 1 part PSv Premix + 2 parts water

This mixture is applied evenly using a bamboo broom and left to dry for approximately 1 hour.

A single coat is never enough. Effective waterproofing requires at least two to three coats—each applied only after the previous one dries. This layered approach ensures a flexible and thick waterproof film.

Dual Top Coating

Two top coats are applied for enhanced durability and protection:

• Each coat consists of 1 part PSv, 1 part water, and 1 part white cement. OR 1 part PSv Premix + 1 part water

• Applied with a 4-inch brush or 10-inch roller.

• After the first top coat dries (1 hour), a second and third coat are added successively for reinforced waterproofing.

Secret 4: Use Reinforcement Materials in Critical Zones

Corners, joints, and cracks need reinforcement to prevent future damage. A waterproofing chemical alone cannot handle expansion and contraction due to heat and rain.

DIY Tip:
Use PPC Crack Mat or a high-quality mesh tape in joints, parapet corners, and pipe outlets. Embed it into the first coat while it's wet, then cover it with the second coat after drying.

Secret 5: Final Water-Repellent Coating

The final layer is pure PSv OR PSv Premix applied directly using a brush, roller, or spray machine.

• This eco-friendly, elastomeric, and heat-resistant formula forms a seamless, high-performance waterproof barrier.

• It shields your terrace from rain, UV rays, and moisture – keeping it cool, leak-free, and protected for years.

Follow the Drying and Curing Time Properly

Even the effective waterproofing Method can fail if you rush the drying process. Each coat must dry completely before the next one is applied. If it's still wet, the layers may peel off or trap moisture.

DIY Tip:
Let each coat dry for 6–8 hours. After the final coat, keep the surface untouched for 24 hours. Light foot traffic is okay after a day, but avoid any water pressure for 72 hours.
