Substrate preparation

1. Substrates must be clean, free of oily residues, loose material, dust etc.
2. Fill large gaps or cracks with elastomeric acrylic filler PRIME FLEX.
3. Very porous and hot surfaces should be lightly dampened; aerated concrete blocks should be primed with solvent based acrylic primer ISOCRYL PRIMER DUR or waterbased acrylic primer ISOCRYL PRIMER DUR.

Mixing instructions

1. Add approximately 8 kg of water in a clean bucket and add gradually under constant stirring 20kg of WALL STUCCO.
2. Stir well until a uniform, lump-free, viscous mixture with desired workability is formed.
3. The working time of the mixture is at least 2 hours.

Application

1. Apply the mixture evenly on the substrate in two coats using a spatula.
2. The first coat 1-2 mm thick covers all cracks and defects.
3. The second coat must be applied when the first coat is fully cured (4-5 hours)
4. For a perfect smooth surface light sanding is advisable after the drying of the second coat.
5. Surfaces are ready for painting within 3 days using SWAN acrylic or emulsion paints.

REMARKS

• †Avoid application on surfaces exposed to direct sunlight or high temperatures.

• Application temperature is +5^oC – +35^oC. Treated surfaces must be protected from fast drying, frost and direct sunlight. Slight dampening is advised at high temperatures to prevent rapid water loss.
