Step-by-Step Guide: How to Waterproof Terrace Yourself
Follow these steps for effective DIY terrace waterproofing:
1. Clean the Surface Thoroughly
Remove all dirt, dust, and debris. Ensure the terrace surface is completely dry before applying any waterproofing solution.
2. Seal Cracks and Gaps
Open all cracks with a grinder or hand tools. Clean out loose cement and debris. For safety, only an experienced electrician or mechanic should operate a grinder.
3. Apply the First Coat with Waterproofing Primer
Mix 1 part PSV Premix with 2 parts water. Apply evenly with a broom or brush so the solution penetrates hairline and larger cracks, sealing them effectively.
4. Seal Visible Cracks, Boundary Joints, and Outlet Pipe Joints
Use PSV Premix and PPC Mat to permanently seal cracks, joints, and pipe outlets. This step enhances durability and ensures a waterproof terrace.
5. Apply Two Coats of Waterproofing
Mix 1 part PSV Premix with 1 part water. Apply the first coat with a roller or brush and allow it to dry for 1–2 hours. Then apply the second coat for long-lasting protection.
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.
Measure the length and width of the terrace using a tape measure.
Multiply length × width to get the total square footage.
