Leak Proof Part Two • Trowel-Applied Paste • For Deeper Voids

JPL LPPT (LeakProof Part Two) is a high-build waterproofing paste designed to fill bigger voids and make the surface abrasion resistant. Applied with a trowel/blade over a 45 GSM nylon mesh reinforcement, it builds an 800–2000 micron crack-bridging film with 12.47 N/mm² tensile strength and 500 hours UV-tested durability.

High-Build Paste — Deeper Voids

Fills bigger voids in a single system — 800 to 2000 microns per coat.

Mesh-Reinforced & Abrasion Resistant

Used with 45 GSM nylon mesh — 12.47 N/mm² tensile, 1.9 MPa flexural strength.

UV-Tested 500 Hours

Per ASTM G 154 — 5.92% elongation at break after 500 hrs of UV exposure.

Strong Adhesion — Exterior Grade

2.2 N/mm² adhesion (ASTM D 790-17), 7.2 MPa compressive strength.

Product Overview

JPL LPPT is the paste-based second half of the JPL Leak Proof two-part waterproofing system. Engineered to fill bigger voids in concrete, RCC and tiled substrates, it must be applied alongside a 45 GSM nylon mesh as a reinforcing agent. The result is a tough, abrasion-resistant, UV-stable waterproofing layer ideal for terraces, basements, swimming pools and slab/expansion joints.

Used with JPL LPPO (liquid, for finer voids) to deliver a complete two-coat waterproofing system with NIL water absorption.

Technical Advantages

A trowel-applied, mesh-reinforced waterproofing paste that fills deeper voids, resists abrasion and stands up to 500 hours of accelerated UV testing.

Anti-Fungal

Resists fungal and algal attack in damp basements, sunken areas and tank surfaces.

Exterior Grade

UV-tested for 500 hrs (ASTM G 154) — built for outdoor terraces, parapets and rooftops.

Water Resistant

NIL water absorption with 80% solid content — a true barrier-grade waterproofing layer.

Tough & Durable

12.47 N/mm² tensile strength, 7.2 MPa compressive (IS-17545-2021), 1.9 MPa flexural.

Indentation Resistant

Abrasion-resistant cured layer — handles light foot traffic on terraces and washrooms.

Colour Fast

UV-stable formulation maintains its finished appearance over time of exterior exposure.

Wet Areas on Fresh Civil Surfaces

Apply the first coat of LPPT with a 45 GSM nylon mesh, ensuring even coverage, and let it dry completely.
Apply a second coat of LPPT after 4–6 hours, followed by two coats of LPPO for added sealing.
Reinforce corners with LPPT, fill visible voids, and ensure uniform application for complete waterproofing.

Basements

Apply LPPT with a 45 GSM nylon mesh over the RCC surface, allow it to dry, and apply a second coat.
Add two coats of LPPO for extra protection, then fill the area with sand and mud for leveling.
Use LPPT for corner coving (100 × 100 mm to 300 × 300 mm), fill visible voids, and reinforce with nylon mesh for thorough sealing.

Slab Joints & Expansion Joints

Cut a mesh of 6" × 1', dip it in LPPT, fold it, and fill the joints.
Allow it to dry completely and repeat the process until all voids are filled, then apply LPPT across the surface.
Finally, apply LPPT and affix an 8"-wide nylon mesh by overlapping through the joint area.

Terrace / Sunken Areas

After first LPPO coat on RCC dries (4–6 hours), apply two coats of LPPT with 45 GSM fiber mesh embedded between them.
Apply mesh on the first LPPT coat while wet; wait 4–6 hours before the second and final LPPT coat.
Close the system with a second coat of LPPO using a roller for a smooth, sealed finish.
