Application Information
Instructions for use

Design Criteria

Vetoproof UM766 use 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 use Vetoseal XX777-50.


Vetoproof UM766 should be applied by brush, trowel or a gaged spreader at a thickness of 0.7mm. Glass fiber scrim and joint tapes can be used on corners and critical areas for reinforcement of the membrane. 

Tiling over Vetoproof UM766 is possible, in such cases sharp sand needs to be sprayed over Vetoproof UM766 while still wet, 24 hours later all excess sand is to be removed and a suitable tile adhesive from Saveto range can be used to bond the tiles directly over the membrane.


Vetoproof UM766 must be allowed to cure for a minimum of 24 hours prior to placing protection. Where damage to the membrane is possible; the membrane needs to be protected by a cementitious screed or protection boards. 

Note: Vetoproof UM766 is not resistant to UV light.


All tools employed for the application of Vetoproof UM766 can be cleaned with Vetonit Solvent XX400 before it hardens otherwise mechanical means are needed.


Surface Preparation

All surfaces where Vetoproof UM766 has to be applied must be clean and have an open capillary system. Eliminate laitance, dirt, grease and other loose materials by means of high pressure water jetting or wet sand blasting. Defective concretes such as cracks and honeycombs, etc. has to be chased out and repaired prior to the application.
