Preparing Concrete Surfaces for Painting
- Leave new concrete uncoated for at least 3 months before painting
- Repair and fill any old or unsound concrete surfaces, allowing adequate time for the filler used to cure
- Once completely dry, brush the surface with a stiff bristled brush to remove any surface dust
- Prime any areas that remain powdery with Farrow & Ball Masonry & Plaster Stabilising Primer
- For interior concrete floors only apply one full coat of Farrow & Ball Masonry & Plaster Stabilising Primer followed by two coats of Farrow and Ball Modern Eggshell allowing the recommended drying times between coats
- Do not use Farrow & Ball Masonry & Plaster Stabilising Primer as a general primer on sound concrete surfaces other than interior concrete floors
Concrete Floors
- Old or unsound surfaces must be repaired and filled allowing adequate time to cure before repainting
- New concrete should be left at least 3 months before painting
- Follow with one coat of Farrow & Ball Masonry & Plaster Stabilising Primer
- For painted concrete floors, clean and remove any surface debris. Rub down any areas that have peeled or blistered to achieve a good 'key'
- Apply Farrow & Ball Masonry & Plaster Stabilising Primer to areas of exposed concrete
Underfloor Heating
- Prior to application, the heating must be switched off for 48 hours to allow the surface area to cool down. Once surface has been painted, allow a further 48 hours before the heating is switched back on
Do not paint in temperatures below 10°C or in excessive heat above 30°C. Avoid painting in direct sunlight. Avoid applying outdoors if there is a likelihood of rain. For best results apply early in the day, allowing the product time to dry before the evening (when condensation can occur).
