Preparation

Ensure all surfaces are sound, clean, dry and free from dirt, grease and other contamination.

New Modern Construction Surfaces:

• Before coating any newly rendered surfaces with any paint system, the render must be permitted to dry out completely and ideally left to weather for approximately 3 months.
• Once completely dry, brush the surface with a stiff bristled brush to remove any surface dust.
• Prime any areas that remain powdery with a 10% diluted coat of Farrow & Ball Exterior Masonry.

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.

Painting Old Exterior Render with Exterior Masonry:

• Please be aware that unsound surfaces may not successfully accept any additional paint layers - therefore if in doubt we recommend you seek professional advice.
• Surfaces with serious structural damage, such as cracking or loose cement, must be repaired before any paint is applied.
• Patch prime any repaired or seriously degraded areas with one coat of Farrow & Ball Masonry & Plaster Stabilising Primer.
• Fungal or algal contaminated surfaces should be decontaminated with a fungicidal wash then left to dry out completely.

Painting Interior Brickwork:

• Farrow & Ball Exterior Masonry may be used on interior brickwork - with the exception of Fletton bricks - but we recommend taking a few extra precautions before and during application.
• Make sure all dirt, mould, salts and other visible contaminants are removed with a stiff bristle or synthetic brush or specialist cleaner, ensuring the brickwork is fully dry before applying any coatings.
• We also recommend checking that all mortar is fully cured before painting.
• Extra care should be taken when painting solid brick walls, and any walls that aren’t damp-proofed, as loss of adhesion may occur and salts may appear.
• We do not recommend the use of Farrow & Ball Masonry & Plaster Stabilising Primer, as this is not intended as a general primer for sound brick surfaces.

Application

Always test a small area of the surface to be painted to ensure you are happy with the finished results

• Stir thoroughly before use.
• Ensure all surfaces are sound, clean, dry and free from dirt, grease and other contamination.
• Once the appropriate surface preparation has been completed, apply two coats of Farrow & Ball Exterior Masonry by brush or roller, taking care not to apply too thickly in any hollows and angled sections.
• Allow the recommended drying times between coats.
• For newly cement rendered surfaces, although Farrow & Ball Exterior Masonry is supplied ready for use, water may be added (at a 10% ratio) to assist application on sound bare surfaces.

Do not use Farrow & Ball Masonry & Plaster Stabilising Primer as a general primer on sound masonry surfaces.

We do not recommend HVLP spray application for large areas such as walls.
