Sikalastic®-10 Primer EP

Two-component, solvent-free epoxy primer for Sikalastic and SikaShield roof membranes

Product Overview

Sikalastic®-10 Primer EP is a two-component, 100% solids, solvent-free epoxy primer designed to prepare substrates before Sikalastic® liquid-applied and SikaShield® bituminous roof membranes. Based on an epoxy resin with special fillers, it penetrates and stabilises low-to-medium absorbent surfaces such as concrete, cement screeds and epoxy mortars, and primes metal when sand-broadcast. It can also act as a binder for scratch coats, levelling layers and repair mortars. Applied by brush, roller or squeegee and back-rolled in two directions, it builds a strong, well-keyed base that promotes adhesion of the subsequent membrane. It serves waterproofing contractors and roofing applicators preparing demanding decks. Space Arc Engineering, an authorized Sika distributor in India, supplies Sikalastic®-10 Primer EP for roofing and waterproofing projects.

It is a solvent-free epoxy primer used to prepare concrete, cement screeds, epoxy mortars and metal substrates before Sikalastic® liquid-applied and SikaShield® bituminous roof membranes, and can also bind scratch coats and levelling layers.

What is the mixing ratio of Sikalastic®-10 Primer EP?

The two components are mixed at a ratio of 79 parts A to 21 parts B by weight. Pot life is around 25 minutes at +20 °C, so mix only what can be used in time.

How much Sikalastic®-10 Primer EP do I need?

Consumption is approximately 0.30–0.50 kg/m² on cementitious substrates and about 0.20–0.25 kg/m² on metal. As a levelling layer it is around 1.0–1.2 kg/m². Refer to the TDS.

What conditions are needed to apply Sikalastic®-10 Primer EP?

Apply at ambient and substrate temperatures of +8 °C to +35 °C, with relative humidity of 80% maximum and substrate moisture of 4% or less by weight.
