For best results, make sure your surface, tools and product are clean before you begin.
New or Unpainted Plaster/Dry-Lined Surfaces
- Make sure the plaster is clean, dry and free of dust, then suitably primed and undercoated prior to painting
- For best results and maximum depth of colour, dilute your Farrow & Ball topcoat with 25% water and use this as a mist coat, followed by two coats of your chosen topcoat
Please Note: British Standard 6150 recommends a typical drying time for new plaster of 7 days for every 5mm thickness.
Previously Painted Walls Preparation
- Ensure all surfaces are sound, clean, dry and free from dirt, grease and other contamination
- Apply one coat of Farrow and Ball Wall & Ceiling Primer & Undercoat, in the correct colour tone for your top coat
- Allow a minimum of 4 hours drying time between coats
- Follow with two coats of your chosen colour to promote adhesion and full colour depth
Painting Over Interior Wall Fillers
For best results always use a filler which has the same porosity and density as the surface which is being repaired. Fillers which have a different porosity or density may lead to visible differences in colour or tone.
- Follow the filler manufacturers application instructions and drying times
- Apply a diluted coat (25%) of Farrow and Ball Wall & Ceiling Primer & Undercoat in the correct colour tone for your top coat
- Allow a minimum of 4 hours drying time between coats
- Follow with two coats of your chosen colour to promote adhesion and full colour depth
Please Note: This product may not be compatible with highly alkaline/cement-based or sand-based fillers. Wherever possible, we recommend using an alternative type of filler. However, if no alternative is available, ensure the filler is adequately sanded and free of all dust and contaminants before proceeding with the steps outlined above.
Using Interior Caulks and Sealants
Where small gaps and cracks require filling or sealing, best results are achieved with an acrylic based decorators caulk which is a water-based, flexible filler. Use the minimum of caulk necessary as a smaller bead will dry quicker and will be less prone to cracking.
- Follow the filler manufacturers application instructions and drying times
- Apply an undiluted coat of Farrow and Ball Wall & Ceiling Primer & Undercoat in the correct colour tone for your top coat
- Allow a minimum of 4 hours drying time between coats
- Follow with two coats of Modern Emulsion in your chosen colour, once again allowing a minimum of 4 hours drying time between coats
Painting Lining Wallpaper
- For unpainted Lining Paper apply one coat if diluted coat of Farrow and Ball Wall & Ceiling Primer & Undercoat (maximum 10% water by volume) in the correct colour tone for your top coat
- Allow a minimum of 4 hours drying time between coats
- Follow with two coats of Modern Emulsion in your chosen colour, once again allowing a minimum of 4 hours drying time between coats
Please Note: : The dilution rate will depend on the porosity of the surface. it is recommended that a test is completed of the level of dilution on a patch to determine the level of dilution required. If you do not want to apply a primer and undercoat, as an alternative, you can dilute the top coat with approximately 10% water and apply as a "mist" coat. Please note: When porous papers are not sufficiently prepared, difficulties in application, variation in sheen or uneven colour may occur.
