Washing after laying:wet the surface well with water before washing. Then use DETERDEK diluted at a ratio of 1:5 or 1:10 (1 litre of product in 5 or 10 litres of water). Apply the solution a few square metres at a time, then add, allow contact time of 5 minutes, then work with a single disc cleaner or large brush.Remove all residues using a cloth or liquid vacuum and rinse with plenty of water. Should any stubborn dirt remain, repeat the wash with more concentrated solutions.For extraordinary maintenance on outdoor surfaces with clear signs of ageing (smog, dust...):dilute 1 litre of product in 10 litres of water. Then follow the same application procedures described above.
