Mixing instructions

GUNITA VALSEC is applied using a gunite spray.

The product consistency should be adjusted by testing water proportions, in both dry- and wet-gunning, in order to attain zero slump and bounce. Test the proportions before applying.

Substrate preparation

Substrates must fulfil the following conditions:

    • They must be strong, clean and stable.
    • Do not use on water-repellent substrates or on substrates with plaster, paint or plastic coating.
    • The substrate should not be excessively dry or waterlogged. In warm weather, dampen the surface before application.

The composition of GUNITA VALSEC does not attack rebar or other metallic components.

Characteristics

Dry blended gunite made from grey cement, selected aggregate and admixtures to provide very good flow without segregation, sag, permeability, low bounce and very good adhesion.
