Note: To ensure the best quality, do not leave everything to the painter’s judgment. You should supervise the work personally and make sure our instructions are followed strictly.
Why DIY Terrace Waterproofing is Important
Over time, terraces develop cracks and absorb moisture, allowing water to seep through. Waterproofing your terrace can:
Prevent leaks into ceilings and walls
Extend the lifespan of your terrace and structure
Avoid expensive future repairs
Materials for DIY Terrace Waterproofing
Before starting, gather the following:
Waterseal PSV – Premix (Best waterproofing chemical for terrace)
PPC Mat crack sealant
Paint roller or brush and Clean water
How to Calculate the Terrace Area for Waterproofing
To get full waterproofing, measure the entire terrace including all four side walls. Water can seep in from any corner, so partial coverage is not recommended.
1.Measure the length and width of the terrace using a tape measure.
2. Multiply length × width to get the total square feet
5 Easy Steps to Stop Roof Leakage: A DIY Guide
If you are wondering how to stop leakage from roof without hiring expensive contractors, follow our proven 5-step method. Using Waterseal PSv Premix, anyone can achieve professional results at a very low cost.
Step 1: Thorough Surface Cleaning
The first secret to successful terrace waterproofing is a clean base. You must remove all dirt, dust, algae, and loose cement flakes.
Action: Use a wire brush or a scraper to clean the floor.
Pro Tip: For the best bond, the surface must be 100% dry and solid. If the surface is dusty, the chemical will not stick properly, leading to future leaks.
Step 2: Crack Identification and Preparation
Visible cracks are the main entry points for water. You need to open these cracks to fill them deeply.
Action: Use a grinder or hand tools to widen cracks into a ‘V’ shape.
Safety Warning: Using a grinder requires skill. If you are not comfortable, always ask an experienced technician to handle power tools. Removing loose debris from inside the cracks is essential for a permanent fix.
Step 3: Reinforcing Joints and Major Cracks
Standard coating is often not enough for corners and joints. These “critical zones” need extra strength to handle heat expansion.
Action: Apply PSv Premix directly on the cracks, boundary joints, and pipe outlets.
Reinforcement: Place a PPC Crack Mat (mesh) over the wet chemical and press it down. This ensures that the joints stay sealed even if the building moves slightly due to temperature changes.
Step 4: Applying the Waterproofing Primer (Base Coat)
The primer coat is designed to penetrate deep into the slab and seal hairline cracks.
Mixing Ratio: Mix 1 part PSv Premix with 2 parts water.
Application: Use a broom or a large brush to spread the solution evenly. This liquid layer reaches deep inside the pores of the concrete, creating a strong foundation for the next steps.
Step 5: Final Dual-Layer Waterproofing Coating
The final step is to create a thick, rubber-like waterproof shield over the entire terrace.
Mixing Ratio: Mix 1 part PSv Premix with 1 part water.
First Coat: Apply using a roller or brush. Let it dry completely for 1–2 hours.
Second Coat: Apply the second layer in a cross-direction to the first one. This double-layer method provides long-lasting protection and ensures your roof remains leak-proof for years.
Note for Homeowners: You can easily supervise a local painter to do this work. By following these specific instructions, you ensure the work is done perfectly without paying high market rates for “experts.”
