Application Information


Surfaces should be clean, sound, dry. As well as free from oil, grease, dirt and loose particles.
Before applying Grundix DP is necessary to test the strength of the base.


Grundix DP is applied directly by brush, roller or spray machine. Grundix DP is used diluted with water in various proportions depending on the porosity of the surface. Dense surface - 1:5, porous substrates - 1:2.
Concentration and amount of Grundix DP must be such that fully absorb into the base without forming a surface layer.
Should be left to dry completely.
Depending on the specific conditions  the following works can be carried out not earlier than 3 - 6 hours after application of Grundix DP.
