PRIMERS
EWI-301 Water-Based Substrate Primer
The Water Based Primer is an essential primer for preparing the wall before installing EWI or render only systems. The primer dries completely colourless and works by limiting the amount of water that the substrate absorbs from the adhesive, thereby ensuring effective application of materials. It provides enhanced adhesion and enables a dependable and durable finish.
Intended Uses
Water Based Primer is designed for priming various different absorptive substrates including ordinary and cellular concrete (e.g. aerated concrete), walls made of bricks, blocks and structural clay tiles, plaster coats, gypsum panels and gypsum plasterboards. It is applied to the substrate prior to the application of paints, adhesives, cement or cement and lime-based plaster coats, skim finish products, ceramic tiling, floor screeds and even wallpapers.
Application Conditions
Application and setting temperature: from +5°C to +25°C.
Water Based Primer 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, work should be postponed.
Water Based Primer should not be applied in rain or humid conditions, or if wet weather is expected before the wash has dried.
Drying time is typically 12-48 hours, although this is dependent upon environment and humidity.

EWI-302 Deep Penetrating Primer
Deep Penetrating Primer is an essential product for preparing the wall before installing EWI or render only systems. The primer dries completely colourless and works to stabilise the substrate, limiting the absorptivity of the substrate and thereby ensuring the effective application of materials. The primer is ideal for newbuild brick and blockwork, providing enhanced adhesion and enabling a dependable and durable finish.

EWI-310 Universal Primer
Universal Primer boosts the adhesion of materials to the substrate. An integral product for smooth substrates where an artificial key is required for binding the materials, the primer contains quartz aggregate to create a textured surface onto which the adhesive layer can bind easily. It is tinted red to enable ease of application and is perfect for ensuring a robust finish.
Intended Uses
Universal Primer is used to prepare the walls before the application of our adhesives. It improves adhesion of the adhesive to the substrate, facilitating application and reducing groundwork absorbency. The presence of quartz aggregate in the primer creates a strong textured surface onto which the adhesive layer can bind easily.
Application Conditions
Application and setting temperature: from +5°C to +25°C.
Product 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, work should be postponed.

EWI-330 Mineral / Acrylic Primer
Mineral/Acrylic Primer is designed for final preparation of a substrate prior to applying the EWI Pro Mineral, Acrylic and Mosaic Renders. While strengthening the substrate, EWI-330 actively balances its absorptivity, facilitating ease of render application and creating an enduring and stable finish. The Mineral and Acrylic Primer can be tinted to match the colour of the render to create a seamless coloured finish.
Intended Uses
The Primer is used to prepare the walls before the application of coloured render. It improves adhesion of the render to the basecoat, facilitating application and reducing groundwork absorbency.
Application Conditions
Application and setting temperature: from +5°C to +25°C.
Mineral/Acrylic Primer 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, work should be postponed.
