Vetoproof UM767

All surfaces to be applied with Vetoproof UM767 must be clean and have an open capillary system. Eliminate laitance, dirt, grease, and other loose materials using high-pressure water jetting or wet sandblasting. Defective concretes such as cracks and honeycombs have to be chased out and repaired before the application.

Priming is not usually required on good quality concrete substrates; however, for highly porous or absorbent concrete, use Vetoseal XX777-50.

Vetoproof UM767 is supplied in two pre-weighed components. Thoroughly stir the contents of the base container. Pour component B hardener into Component A container and mix well with a mechanical jiffy-type mixer operated at low speed. Scrape the side of the container to ensure the entire product has been properly mixed.

Apply Vetoproof UM767 by a brush, trowel, or a gaged spreader at a thickness of 0.5 mm. Use glass fiber scrim and joint tapes on corners and critical areas for membrane reinforcement.

Tiling over Vetoproof UM767 is possible; in such cases, spray sharp sand over Vetoproof UM767 while still wet, 24 hours later, remove all excess sand, and use a suitable tile adhesive from Saveto Tiling Systems Product Range to bond the tiles directly over the membrane.

Allow Vetoproof UM767 to cure for a minimum of 24 hours before placing the protection. Protect the membrane with a cementitious screed or protection boards where damage to the membrane is possible.

Note: Vetoproof UM767 is recommended for interior applications.

Clean all tools employed to apply Vetoproof UM767 with Vetonit Solvent XX400 before it hardens; otherwise, mechanical means are needed.
