About this product

Preparatory key coat for rendering

• To achieve a good key for rendering onto smooth or otherwise unsuitable but sound surfaces
• Ideal as a pre-treatment for renderings required to resist severe exposure conditions
• Suitable substrates:
  dense concrete
  brickwork
  blockwork
  masonry
  clean, sound, well adhered
  existing render (<19mm)

Features and Benefits

• Equalises suction on mixed backgrounds
• Provides excellent suction control across both high and low suction substrates
• Resists the penetration of external water to improve the weather resistance of rendering systems
• Quality controlled and factory blended to give a consistently high quality product
• Easy to apply by hawk and trowel and/or roller

Constraints

Do not apply to gypsum plaster or previously painted surfaces.

For applications where the codes of practice recommend sulphate resistance, use only the sulphate-resistant cement formulation.

Coverage

For each mm of thickness, you will require approximately 1.4 kg per m2. When trowel applied to a thickness of 2 – 3 mm, coverage is approximately 7.5 m2 per 25 kg bag.

Note: These estimates take no account of wastage and will vary according to the type of substrate. Allowance must be made for extra material required on high suction or
uneven substrates.

Delivery 2-3 working days.
