Enables coatings to be applied to hard, smooth surfaces which would usually reject paint. Avoid using any coating which includes a strong solvent. For more information, please download a product datasheet from the quick links below. 

Please note: Whilst Powerfloat Primer avoids the use of mechanical preparation, diamond grinding or shot blasting does provide a better finish overall and is recommended. For smaller areas where mechanical abrasion is difficult Powerfloat Primer is a great back-up option.

Surface preparation

New concrete should be allowed at least 28 days to dry. Surfaces should be clean, dry and free from oil, grease, dust, dirt and other contaminants. Existing coatings should be well bonded and sound.


The tall outer tin contains a tin of Resin and a tin of Activator. Remove these two tins and stir the contents of each thoroughly. Decant both tins into the tall outer tin. The two components should then be very thoroughly mixed together using a wide bladed stirrer. A wooden batten at least 25mm wide is ideal. Mix for 2–3 minutes until an even colour and consistency are obtained.


If appearance is critical we recommend the Application of a small trial area first.

Decant the mixed components into a roller tray and apply using a medium pile type roller. A brush may be used for cutting in. Aim to apply the mixed components within one hour (they are usable for up to 2 hours maximum at 20°C). Do not apply at temperatures below 10°C or above 30°C. Cold or damp conditions may retard or prevent full curing. Avoid applying too thickly.
