Application note
The concrete surface must be completely dry, clean, compact, with no grease or stains, if there has some obvious cracks and breaking area, it should be fixed in advance. Make sure to clean up the surface with air grinding or vacuum method prior to apply SWD8009.
This product can be applied on the temperature under -10℃. When apply on the very low temperature, put the material drums in the air-conditioning room for more than24h.
SWD recommends to agitate the coating uniformly prior to application, use up the mixed materials within 1 hour. Don’t pour the rest liquid to the original bucket.
The viscosity of product is set up in the factory, thinner shall not be random added by the applicators. Call the manufacturer for instructions to add special thinner if the viscosity changed with the application environment and humidity.
