Hand / Machine Applied - K1 Spray can be easily hand or machine applied
Application:
ONE COAT / FINISH COAT
One coat is applied directly onto block work (please seek advice from our Technical Support Team) and must be finished to a minimum of 16mm thick to avoid 'ghosting'
The material should be applied 18mm thick in 2 passes; the first pass 6-8mm and the second pass 12-14mm. (See also under Spray Application). After setting, 2mm is scraped off for a 16mm finish
If the material is being used in a two coat application the finish coat is applied over a K Rend Base Coat to line level, using a Darby or straight edge, to a minimum thickness of 10-12mm. When straightening, hollows should be filled out immediately before a skin is formed
Care should be taken to avoid small hollows, which can make it difficult to achieve a good finish. Small areas such as quoins, reveals and bands can be left with a plastic float
Do not polish
