Cleaning Prior to Painting

1. For most surfaces it is recommended to use a diluted Sugar Soap solution following the manufacturers instructions
2. It is not recommended using solvent-based cleaning products or strong alkaline solutions as these can impact adhesion
3. After cleaning, wipe the surface with a damp cloth and allow to dry

New Modern Construction Surfaces

1. 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
2. Once completely dry, brush the surface with a stiff bristled brush to remove any surface dust
3. Prime any areas that remain powdery with a 10% diluted coat of Farrow & Ball 15 Year Exterior Masonry

Preparing Concrete Surfaces for Painting

1. Leave new concrete uncoated for at least 3 months before painting
2. Repair and fill any old or unsound concrete surfaces, allowing adequate time for the filler used to cure
3. Once completely dry, brush the surface with a stiff bristled brush to remove any surface dust
4. prime any areas that remain powdery with Farrow and Ball Masonry & Plaster Stabilising Primer
5. For interior concrete floors only apply one full coat of Farrow and Ball Masonry & Plaster Stabilising Primer followed by two coats of Farrow and Ball Modern Eggshell allowing the recommended drying times between coats

Painting Interior Brickwork

1. Make sure all dirt, mould, salts and other visible contaminants are removed with a stiff bristle or synthetic brush or specialist cleaner
2. Ensure the brickwork is fully dry before applying any coatings
3. It is also recommended that all mortar is fully cured before painting
4. 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

4. Extra care should be taken when painting solid brick exterior walls, and any walls that aren't damp-proofed, as loss of adhesion may occur and salts may appear

Always make a test area before the application to judge the suitability of the product. Follow the manufacturer's instructions at all times. Ensure all surfaces are sound, clean, dry and free from dirt, grease and other contamination

Please note: Darker/stronger colours may require additional coats. The drying and recoat times provided are based on applying paint in normal conditions. Drying times may be longer in cooler and/or higher humidity environments. Darker colours may take longer to dry. Allow a minimum of 14 days before applying over solvent based coatings.

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 to dry before the evening.

New Modern Construction Surfaces

1. Once the appropriate surface preparation has been completed, apply two coats by brush or roller
2. Take care not to apply too thickly in any hollows and angled sections
3. Although supplied ready for use, water may be added at a 10% ratio to assist application on sound bare surfaces.
4. Do not use Farrow & Ball Masonry & Plaster Stabilising Primer as a general primer on sound masonry surfaces

Painting OId Exterior Render with Exterior Masonry

Painting Over Exterior Wall Fillers

1. For best results always use a filler which has the same porosity and density as the surface which is being repaired
2. Fillers which have a different porosity or density may lead to visible differences in colour or tone
3. Follow the filler manufacturers application instructions and drying times
4. Apply a diluted coat (20 - 25%) of Farrow & Ball 15 Year Exterior Masonry
5. Allow a minimum of 4 hours drying time between coats

Advice for repairing Damage and Touching In

If your paintwork becomes damaged or marked you may need to repaint. To achieve the best results it is recommended applying a single coat of paint over the entire wall or walls that have the damage, using the same batch of paint you originally carried the work out with. This best practice will avoid any noticeable variation in colour or finish. If you do chose to touch-in to repair damage, the following recommendations will help you achieve the optimum finish.

1. Always aim to use the same batch of paint. If you use a different batch, although the control colour is to tight specifications, you may observe slight colour and sheen variations. If you are unable to use the same batch of paint it is recommended that you apply a single coat of a different paint batch to an entire wall as any slight variations will be much less noticeable when observing from wall to wall
2. Always use the same preparation techniques when you make any repairs you used when you originally painted the wall
3. Always use the same application tool and method as when you originally painted the wall
4. Ensure that the edges of the touched in paint are blended in to make the transition between old and new paint areas less noticeable
