Pitch-modified elastomeric polyurethane liquid applied waterproofing membrane
Vetoproof UM765 is a premium quality pitch extended polyurethane waterproofing membrane; the product is liquid applied that hardens through reaction with atmospheric water vapor to form a highly elastic rubbery jointless membrane that is resistant to aggressive groundwater and sewage. Vetoproof UM765 can be applied at 0.5mm on vertical application.

Theoretical Coverage: 2m²/L @ 0.5mm thickness.
Stated consumption data are for general guidance. Actual consumption depends on the nature of substrate, method of application, and wastage.
The original sealed pail of Vetoproof UM765 has a shelf life of 6 months, provided it is stored in original sealed containers clear of ground in a dry and shaded place below 35ºC.
Vetoproof UM765 usage follows the guidelines of EN BS8102:2009 and CIRIA report No. 139 and ASTM guides C1417 nad 898.
Priming is not usually required on good quality concrete substrates; however, for highly porous or absorbent concrete, use Vetoseal XX777-50.
Apply Vetoproof UM765 by brush, trowel, or a gaged spreader at a thickness of 0.5mm. Use glass fiber scrim and joint tapes on corners and critical areas for reinforcement of the membrane.
Tiling over Vetoproof UM765 is possible; in such cases, spray sharp sand over Vetoproof UM765 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 UM765 to cure for a minimum of 24 hours before placing protection. Protect the membrane with a cementitious screed or protection boards where damage to the membrane is possible.
Note: Vetoproof UM765 is not resistant to UV light.
Clean all tools employed to apply Vetoproof UM765 with Vetonit Solvent XX400 before it hardens; otherwise, mechanical means are needed.
All surfaces to be applied with Vetoproof UM765 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, etc., have to be chased out and repaired before the application.
Some people are sensitive to resins, hardeners, and solvents. Wear suitable protective clothing, gloves, and eye protection. If working in confined areas, appropriate respiratory protective equipment must be used. The use of barrier cream provides additional skin protection. In case of skin contact, rinse with plenty of clean water, then cleanse with soap and water. Do not use solvent. In case of contact with eyes, rinse immediately with plenty of clean water and seek medical advice. If swallowed, seek medical attention immediately - Do not induce vomiting.
Vetoproof UM765 is flammable, do not use near to open flames.
