Application Instructions
Preparation
Ensure the substrate is dust-free, grease-free, and pre-wet with water before application. Patch all grooves, voids, and honeycombs before applying Estoflex GP. Estoflex GP can be applied on damp surfaces without standing water. Do not apply Estoflex GP on surfaces with live leaks; first, stop all existing water leaks using Estop Waterplug.
(A) As a damp proof & protective coating
Estoflex GP should be applied with a brush, rubber squeegee or flat trowel. The system consists of one priming coat (30% water to 70% Estoflex GP) and two neat coats, each applied after the previous coat has dried. Firstly, apply the priming coat at a dosage of 0.35 kg/m². Then, apply two layers at a rate of 0.75 – 0.90 kg/m² each, following the drying of the priming coat.
B. As a waterproofing and vapour proof system
For R.C. flat roofs, lay a base screed with a minimum 1:120 gradient if the floor is uneven. Apply Estoflex GP with a brush, rubber squeegee, or flat trowel. Start with a priming coat (30% water to 70% Estoflex GP) at 0.35 kg/m². Once dry, apply the first neat coat at 0.75 – 0.90 kg/m², followed by the second and third coats at the same rate, allowing each coat to dry thoroughly.
C. As Primer for Waterproofing bitumen
membrane and shelf adhesive membrane Application of Estoflex GP as primer shall be applied with brush, rubber squeegee or flat trowel Dosage for waterbase primer – Estoflex GP is apply at the rate of 0,35 kg/m2 ( with ratio 30% water to 70% of Estoflex GP) , depending on the porosity of the surface, and allowed to dry completely before application.
