What is the difference between Premium Basecoat and other basecoats?

The main difference between Premium Basecoat and other basecoats, such as EPS Basecoat Adhesive (EWI-220), is that Premium Basecoat contains white portland cement and a high concentration of polymer-modified binders and synthetic fibres, delivering flexibility, higher crack resistance, and improved durability.

Can I use Premium Basecoat as an adhesive?

Premium Basecoat can be used to fix Mineral Wool (Rockwool) slabs to a substrate as it has very good adhesion to Mineral Wool.

How much water do I need to mix Premium Basecoat with?

You should mix approximately 6 litres of water per 25kg bag of Premium Basecoat. There is a time of usability after mixing with water of approximately 20 hours at a temperature of +20°C.

What temperatures can I use Premium Basecoat in?

Premium Basecoat can be applied in a temperature range of +5°C to +25°C. The average drying time for Premium Basecoat is approximately 12-48 hours, depending on weather conditions. The drying period may be significantly longer in low temperatures and high relative humidity.

Do I need to use a substrate primer before using Premium Basecoat?

We highly recommend that you prepare the substrate using our EWI-301 Water-Based Substrate Primer (or EWI-310 Universal Primer if a key is required) before applying the basecoat layer. This will improve the Premium Basecoat’s adhesion to the substrate.

Coloured Render Sample Pot

Our Coloured Render Sample pots contain 600g worth of thin coat render (1.5mm grain size) residue. Each pot comes pre-mixed in your selected colour. Our sample pots are intended to allow you to test the render colour on a small area of the property. The render needs to dry and set (48-72 hours at least) to represent the actual colour. Do not form a judgement of the colour when the product has just been applied.

Coloured Render Sample Pot Application

Application and setting temperature (air, substrate, materials): from +5°C to +25°C. Ensure the walls are clean and free from debris. Avoid applying render colour sample onto dusty or wet surfaces. Grain size of sample pot: 1.5mm. Note: if you are going with 1.0mm or 2.0mm grain size, then the final colour may turn out to be lighter or darker due to the shading factors hitting the grains.
