Lastick Band Damptect

1.Surface preparation:

The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease.

All surface imperfections, protrusions, structurally unsound and friable concrete must be removed and repaired with a suitable concrete repair mortar.

2.Priming:

Apply (solvent based primer) @ 4-6 $\text{m}^2$/L to a clean smooth and dry surface by brush, roller or spray.

Allow the primer to dry prior to the application of the band. As the viscosity of the primer is low, it easily penetrates into the concrete pores which promotes the adhesion between the band and the concrete surface. In addition to that the primer also acts as a binder for the dust which gets accumulated on the concrete surface even after cleaning.
