Preparation & Application

Surface Preparation

All surfaces must be sound, clean, dry and free from any material which may impair adhesion onto the masonry. Cracks and damaged surfaces must be repaired with a suitable cement-based product or suitable crack filler. Mask around areas where material is to be applied. Masking tape must be removed before the material has dried. Absorbent surfaces should be primed with a suitable bonding agent.

Mixing

weber.cote Barrier Cement-based Decorative Waterproof Coating is a fine powder.

  • Mix with 1.4 litres of clean water by volume.
  • Loosen the powder by shaking, and mix one volume of powder with one volume of clean water to a creamy consistency. First add the water then the powder.
  • Mix only enough material that can be used in 30 minutes.

Application

Do not apply to exterior surfaces if temperatures drop below 5ºC or rise above 30ºC, in damp and wet conditions or on elevations in direct sunlight or hot substrates, or if rain is imminent. It is essential that the first coat of weber.cote Barrier Cement-based Decorative Waterproof Coating is brushed well into the surface with a soft paint brush. The second coat can be applied after the first coat has thoroughly dried (after 24hrs).

Coverage

Depending on suction, surface porosity and texture, coverage is approximately 1m2 / kg per coat.

Curing

Curing with a fine mist spray of clean water may be necessary during rapid drying conditions. In hot climates curing as above is essential for 3-5 days after application.
