application instruction
all surfaces to be waterproofed should be clean, sound and dry. priming of good quality, dense concrete is not necessary. for absorbent surfaces such as porous concrete a mixture of 1 part nitoproof 600 and 1 part xylene is used to seal the surface. bitumen and asphalt surfaces require priming with nitoproof 600 primer as a barrier to protect the membrane.
nitoproof 600 primer can be applied by brush or roller and allow to cure for 4-8 hours after application. do not allow primer to harden completelly before proceeding with nitoproof 600 application
