Description
AdoFloor and Wall Seal 25L Polymeric coating provides a clear, tough and water repellent protection to exterior surfaces, such as concrete, natural stone, brick and block paving. It also binds together surface particles producing a toughened self-cleaning finish and penetrates hair line cracks to provide a flexible seal.
AdoFloor and Wall Seal restricts moisture penetration to give excellent resistance to the effects of weathering and atmospheric pollution and will not yellow after prolonged exposure.
Surface Preparation
Surfaces should be sound, clean, free of cracks, and all traces of dust, paint, oil or other contaminants. Any surface moisture will hinder penetration, therefore the surface should be dry to the touch. Joints in paving should be sound, but if not they should be raked out and repointed with sand/cement mortar incorporating ADOBOND SBR.
Any cracks in concrete should be treated in a similar manner.
Application
A wide soft brush, roller or spray can be used. Best results will be obtained by the use of a spray. This should be of a low pressure airless type, without atomisation of material at the nozzle. Firstly a light mist coat should be applied followed by a heavy flood coat within 20 to 30 minutes whilst the first coat is still tacky. Generally one flood coat is sufficient. However, when surfaces are very porous, or when a glazed finish is required, a second flood coat should be applied, again whilst the surface is still tacky. Optimum performance will be obtained when the surface will absorb no further material. Treatment should not be undertaken in freezing temperatures. The treated surface should be protected from rain for at least 30 minutes following final application.
Caution
Care should be taken to ensure that AdoFloor and Wall Seal does not come into contact with surfaces which could be affected by solvents, such as paint.
Cleaning of Equipment
Immediately after use equipment should be emptied and then cleaned with white spirit.
Physical Data
Characteristics: AdoFloor and Wall Seal 25L is a low viscosity, free flowing liquid.
Curing
The surface is fully water repellent when the coating is tack-free, however the reaction of the silicone resins in AdoFloor and Wall Seal continues for up to four weeks, to create an in depth moisture barrier.
Depending upon surface absorbency, 1 litre of AdoFloor and Wall Seal will cover 6-8 m2 as a mist coat and 3-4 m2 as a flood coat.
