PRODUCT DATA

C.T.W. Damp Surface Primer Sealer is a remarkably successful moisture compatible epoxy resin priming sealing system comprising a very simple to mix and use twin-pack coating which can be applied directly to damp, or wet surfaces (standing water having been removed) for receiving subsequent coverings or coatings etc, which are unable to tolerate immediate contact with moisture. Further it offers a tough, resilient, impermeable brush/roller applied covering for protection of steelwork, walls, floors etc, from corrosive, fume and splash. With the addition of non- slip aggregates (average 15-20 g/m2) two coats gives a very efficient slip-resistant surfacing for steps, ramps and general floor areas. . It is according the European Standard EN 13813 Screed materials and floor screeds - Screed materials - Properties and Requirements

PREPARATION

Concrete substrates must be free from loose material, dust, laitence, debris and other contaminants. Any oil or grease deposits can be removed by a hot detergent wash with a suitable cleaner. Any laitance or ingrained oil and grease may require mechanical work.

MIXING

C.T.W. Damp Surface Primer Sealer is supplied in a two part system, and has a base and hardener components.
The Hardener should be added to the Base and stirred thoroughly for at least 2 minutes with a suitable slow speed drill and paddle. On slabs, puddled areas of water must not remain. On formed surfaces no running water may be evident.

APPLICATION

Apply the mixed material to the concrete surface using a brush or roller. Brush out any primer which puddles in low areas on slabs (horizontals) or runs or sags on formed surfaces (verticals) during application.
If primer is left for more than 24 hours before overcoating it will be necessary to re-prime.
