Mixing instructions

Add 6 litres of water per bag of VALCOL JUNTA UNIVERSAL, i.e. 0.30 litres/kg. Mix by hand or with a slow electric mixer until obtaining a smooth paste. The consistency should be that of cement–based adhesive. Let stand for 5 minutes before using. Then mix again.

The working time for VALCOL JUNTA UNIVERSAL is approximately 90 minutes from preparation.

Substrate preparation

Joints between tiles should be dry and clean (i.e. without dust, surface grout, loose particles or any other material that impedes good adhesion).

It is advisable to wait 24-48 hours after laying the pavement before grouting. When grouting porous or rough ceramic tiles, protect them with a primer to avoid staining and for ease of cleaning.


Mortar made from cement, graded aggregate, resins, organic and inorganic admixtures, and pigments.

Instructions for application

Spread VALCOL JUNTA UNIVERSAL on the joint with rubber float, working diagonally and ensuring that the grout penetrates properly.

Once the grout starts to harden, when the surface sheen of VALCOL JUNTA UNIVERSAL begins to fade, remove excess grout with a wet sponge. Apply to a small area at a time, cleaning as you go. Final cleaning, with a dry or damp cloth, should be done once the grout has hardened.

Do not use the product at an ambient temperature below 5ºC or above 35ºC.
