New Terrace Waterproofing – A Complete Guide for New Construction
Proper New Terrace Waterproofing is one of the most important steps in any construction project. Many homeowners believe that mixing any chemical suggested by a contractor or purchased from a hardware store is enough. But true waterproofing is much more than that. When done correctly—using the right chemicals, in the right proportions, and applied by a certified waterproofing specialist—it protects your home from water leakage, dampness, structural damage, and mold growth, ensuring long-term durability and peace of mind.
Why New Terrace Waterproofing Matters
Contractors usually focus on making a building strong and visually appealing. However, waterproofing is equally important. For example, a properly designed slope ensures rainwater drains quickly, while well-placed outlets prevent water from stagnating on the roof.
Ultimately, terrace waterproofing is the homeowner’s responsibility. Once the roof slab is filled and cured, waterproofing should be completed before plastering, tiling, or applying china mosaic. Paying attention to quality waterproofing at this stage can help you avoid costly leakage and repair issues in the future.
Step-by-Step Guide to New Terrace Waterproofing
1. Roof Curing
After the roof slab is cast and the shuttering removed, the terrace must undergo water curing for 3–4 days. This process strengthens the concrete and prepares it for waterproofing.

2. Choosing the Right Waterproofing Chemical
The market is filled with different waterproofing products, but not all are reliable. Cheap, low-quality chemicals often fail under harsh weather conditions. To ensure long-lasting protection, you must use the right material with the correct mixing ratio and proper application technique.

New Terrace Waterproofing Method
Surface Preparation Before Waterproofing
Grinding & Cleaning – Remove loose material such as brick chips, sand, concrete waste, or iron rods from the surface.
Pressure Washing – Wash the entire terrace with a pressure washer to remove dust and debris, leaving the surface clean and ready for waterproofing.
Application of PSV Premix Waterproofing
First Coat (Primer)
Mix 1 part Premix with 2 parts water (1:2 ratio).
Apply evenly using a brush or spray.
This seals cracks and pores.
Allow to dry for 1–2 hours.
Second & Third Coats
Mix 1 part Premix with 1 part water (1:1 ratio).
Apply the second coat evenly, let it dry for 1–2 hours.
Apply the third coat in the same way.
This 3-layer waterproofing system creates a durable, protective barrier. Even if future tiles, plaster, or china mosaic develop cracks due to weather changes, the underlying waterproof layer keeps your terrace safe.
