The PPG Architectural Coatings Oil Based Pigmented Sealer is an adhesion of topcoats to plaster surfaces, brickwork, masonry, timber and most wallpapers*.
Sealer Primer Undercoat
Surfaces must be clean, dry and free from all surface contamination. Treat mould with bleach and then rinse with clean water. Fill in the surface defects with suitable filler or sealant.
Age new set plaster for 8 weeks before painting. Age new concrete & cement render 4 weeks before painting to allow the alkalinity to reduce.
Touch dry in 4 hours and re-coat after 16 hours. In damp or humid conditions drying time may be lengthened.
Apply one coat (unthinned) by brush, roller or spray. Keep brushes and rollers working freely by rinsing with solvent or mineral turpentine occasionally. Provide adequate ventilation during use.
Do not paint at temperatures below 10°C or above 30°C, when humidity is high or rain is imminent (for exterior).
Up to 16m² per litre, depending on the nature of the surface. Coverage on rough and/or porous surfaces will be lower.
Mineral turpentine, keep away from drains.
Designed to work best with oil based topcoats. However, coating with water based topcoats is acceptable but leave additional curing time.
* Most wallpapers can be painted over but must be tested first. Test PPG pigmented sealer in an inconspicuous area. If the wallpaper blisters or the PPG pigmented sealer does not dry as expected, remove the wallpaper and treat the surface as paper faced plasterboard.
