SPREADING RATE: Approximately 8 – 10m² per litre (as a keying agent and bonding liquid. depending on surface porosity)
POLYMER TYPE: Modified styrene/butadiene polymer
DRYING PROPERTIES: Product is tacky within 15 minutes
PACKAGING: 1L, 5L & 20L
THINNING: No thinning is required. Product is supplied ready to use
CLEANING: All equipment should be cleaned with water before the product has dried. Dried or hardened product may be removed using lacquer thinners
APPLICATION METHOD: Loose and powdery surfaces with little strength are not suitable for Plaster lock applications. Keep out of reach of children. Prolonged heat or excessively cold conditions may damage or affect the performance of the product.
DO NOT PAINT
- IF THE TEMPERATURE IS BELOW 10° C OR ABOVE 35° C
- IF THE SURFACE IS DAMP (MOISTURE READING ABOVE 15%)
- IF IT IS RAINING OR RAIN IS FORECAST
- BEFORE 9H00 AND AFTER 16H00 IN THE WINTER
SURFACE PREPARATION: All surfaces must be clean, dry and free of oil, dirt and dust, loose particles, flaking paint or any other surface contamination.
APPLICATION: As a keying agent for plasters and cementitious products: Apply liberally to the floated off shutter concrete, plaster, wood or vinyl surface. Plaster while the surface is still tacky. Plaster lock is not suitable for keying onto bituminous or oily surfaces. As a bonding liquid in cement based compounds, mortars and adhesives: Mix Plaster lock diluted 3 times with the dry cementitious powder, in place of the water which would normally be used in the mix. As an ad-mixture: Mix 20 parts Plaster lock with 50 parts OPC to give a water resistant tough mortar.
HEALTH & SAFETY: Keep paint away from children. Never smoke, drink or eat while painting. Wear protective overalls, gloves and goggles. If accidental contact with skin should occur, wash immediately with clean water. Harmful if swallowed. Do not induce vomiting. Consult your doctor. Ensure good ventilation during application and drying. Store in a cool, dry place out of the sun.
