Use and typical specification

DULUX AcraTex 500/6 Exsulite Render is principally designed to provide both the adhesive bond between substrate / polystyrene insulation board and as the surface matrix render layer of the Exsulite Coating / Cladding System. Other uses for this product include patching imperfections in masonry substrates. DULUX AcraTex 500/6 Exsulite Render is an ideal leveller ( render) of uneven masonry or where a smooth level is required.

Typical properties and application data

Application Guide AcraTex 500/6 Exsulite Render requires the addition of fresh grey Portland cement at the following ratio:- 3 parts 500/6 Exsulite Render 2 part fresh Portland cement NOTE: Ensure thorough mechanical mixing of the two components. AS THE ADHESIVE FOR POLYSTYRENE BOARD. AS THE MATRIX REINFORCEMENT RENDER. It is applied to the surface in a layer by Plastering Technique (Hawk and Trowel) approximately 1-2mm thick, whilst fresh and wet apply a length of Exsulite Reinforcement Mesh. Using the trowel , smooth out mesh wrinkles. Deliver a further 1mm of DULUX AcraTex 500/6 Exsulite Render to totally embed mesh and subsequently and lay off to produce a uniform finish. A. CURING TIME 7- 10 Days dependent on weather conditions. For full details refer to individual Duspec Product and AcraTex Applicational Data Sheets.
