Practical: Practical coverage depends on many factors such as porosity and roughness of the substrate and material losses during application

After cleaning 3486 can be applied directly to the substrate. Minimum wet film thickness 1mm. In case of repeatedly repaired spots, important or active cracks apply 3486 crosswise over the cracks or fissures.
