EWI-269 Lightweight Basecoat

FOR RENDER-ONLY SYSTEMS

Product Overview

The Lightweight Basecoat is a breathable, vapour-permeable, lime-based basecoat suitable for both old and new buildings. Once cured, it forms a strong yet flexible layer and can be applied internally or externally. The material can be built up to 20mm in a single pass without compromising breathability, with the lime content helping to reduce the risk of cracking on softer substrates.

Intended Uses

Lightweight Basecoat is ideal for heritage and modern construction, including high-performance blockwork, AAC, calcium silicate blocks, stonework and solid brick walls. It is used as a levelling and basecoat layer prior to reinforcement and finishing coats. For high-performance blockwork, two passes are recommended. Minimum application thickness is 8–10mm, where reinforcement and finishing coats will follow.

Application Conditions

Lightweight Basecoat should not be applied in rain or humid conditions, or if wet weather is expected before the adhesive has fully set.

The basecoat should be applied in temperate weather and should not be used in temperatures above 30°C. Likewise, if the materials or the substrate are frozen, or if there is any risk of frost damage within the first 24 hours, work should be postponed.

Setting time is typically between 24-48 hours, depending upon the environment and humidity.

EWI-269 should be mixed with approximately 5 litres of clean water per 25kg mix.
