Installation
1) At least apply2layers or 2.7mm
2) Usage: (1layer use0.7—1mm/㎡)
0.7mm/㎡ usage is 1.2-1.3kg
1mm/㎡ usage is 1.4-1.5kg
3) 30kg liquid rubbercoating material mix with 0.9—1.2kg PU resin and 100-180gram water, applied byrubber squeegee
4) After 1 layer, itshould maintain about 10-12 hours, ensure the firstly layer are dry, then thenext process.
5）Wheninstall the firstly layer on concrete base ,we suggest 30kg liquid rubber coatmaterial mix with 180gram silica sand .(It is better to seal the sub-base moistures)
