Finco (Finex Eng.): Waterproofing: Barralastic (Masterseal 540)

Coverage:  Actual coverage depends upon the method of application, the texture and porosity of the surface. Therefore material requirement is approximately 2 kg/m² for a total dry film thickness of 1 mm (± 0.1 mm) in two coatings.

Preparation: Correct substrate preparation is critical for optimum performance. Surfaces should be structurally sound, clean and free from laitance, loose particles, oil and grease, old coatings, curing compounds or any other contaminants. Remove oil or grease and wax contaminants by scrubbing with industrial grade detergent or degreasing compounds before mechanical preparation. Cement laitance, loose particles, mold release agents, curing membranes and other contaminants must be removed.

Application: Mechanical mixing is necessary. Heavy duty electric drill with a wing type paddle is recommended. Place approx. 75% of Part A of the pack in a clean bucket. Keeping the mixer running, add the Part B slowly. Mix for at least 3 minutes to get a lump-free homogeneous mix. While continuing to mix, add all of the remainder of Part A if applying on a horizontal surface, or a part of it if applying on vertical surfaces till the required consistency is obtained. Allow to stand for 2-3 minutes and remix before application.
