How to seal against ground moisture and increased residual moisture in cementitious substrates? WITH UZIN PE 480.

Long waiting times through moist substrates and the associated high drying costs present a problem especially with tight deadlines. The 2-component epoxy moisture barrier UZIN PE 480 is ideally suited not only for priming and reinforcing but also especially for sealing cementitious substrates without limitation to a max. residual moisture value.

The application safely seals very high moisture contents in concrete floors or cementitious screeds. Combined with the enormously quick super-fast primer UZIN PE 280, a surface is created which presents an optimal bond to the subsequent levelling compound layer.

We have developed UZIN PE 480 for substrates not able to dry to the standard-conforming permissible residual moisture but still need to be quickly ready for covering.
