Perfect Preparation & Application: Preparing Exterior Masonry
The following guidelines apply to the Exterior Masonry finish, suitable for exterior surfaces constructed of masonry, cement, stone, brick, block work, roughcast and chip
Ensure the surface is sound, clean, dry and free from dirt, grease and any other contamination.
FOR NEWLY RENDERED SURFACES:
- Newly rendered surfaces must dry out completely and are best left to weather for up to three months before sealing with any paint system.
- Once completely dry, prime any areas that remain powdery or unstable with one coat of Masonry & Plaster Stabilising Primer.
FOR STRUCTURALLY DAMAGED SURFACES, SUCH AS CRACKING OR LOOSE CEMENT:
- Repair damaged areas before applying paint. If in doubt seek professional advice.
- Patch prime any repaired or seriously degraded areas with one coat of Masonry & Plaster Stabilising Primer.
FOR UNSOUND SURFACES, SUCH AS ALKALINE, POWDERY OR POROUS SURFACES:
- Prime with one coat of Masonry & Plaster Stabilising Primer, working well into the surface.
- Allow to fully dry.
FOR FUNGAL OR ALGAL CONTAMINATED SURFACES:
- Decontaminate with an appropriate treatment or with a solution of diluted bleach and allow to dry completely.
- Scrape back unsound surfaces and brush clean before applying one coat of Masonry & Plaster Stabilising Primer.
- When using more than one tin of the same colour check that the batch numbers are the same (see the base of the tin). If not then mix the tins together before use.
- Stir paint thoroughly before use.
- Apply two coats of Exterior Masonry using a brush or roller, taking care not to apply too thickly in hollows and angled sections.
- On application of the final coat lay off the paint in a single direction.
- Exterior Masonry is touch dry in two hours and can be recoated in five hours.
- Clean brushes and rollers with warm soapy water.
