Mixing instructions

Mix VALSEC REPARACIÓN with 17% clean water to obtain a smooth paste. The mix can be prepared manually or mechanically.

The working time is 30 minutes depending on the environmental conditions. When preparing the mortar, use the same amount of water and mixing time for the entire process. Do not re-mix or use any admixtures without authorisation from the manufacturer.

Substrate preparation

Substrates must fulfil the following conditions:

  • They must be strong, rough, clean and stable.
  • Do not use on water-repellent substrates or on substrates with plaster, paint or plastic coating.
  • Defective areas must be cleaned and chiselled.
  • Restore or remove rusted or damaged reinforcement.
  • In very porous concrete surfaces, dampen the substrate before application.
Instructions for application

Lay the mortar on the substrate using a trowel, filling the surface to be repaired, and compacting the product. For layers over 10 mm thick, apply in successive layers of 5 mm max. Wait until the previous layer has hardened before applying a new layer. Power trowel the surface about 40 minutes after application.
