White.

Mixing instructions

Add approximately 6.5 litres of water per bag of VALCOL YESO (C1T). Mix by hand or with a slow electric mixer to obtain a smooth paste. Let stand for 5 minutes before using. Then mix again.

VALCOL YESO (C1T) should be used within about 90 minutes of mixing.

Substrate preparation

The substrate must be flat, dry, solid, clean (without dust, surface grout, loose particles or any other material that impedes good adhesion: paint, concrete release agents, etc.).

The substrate must be level. Use a 2 metre ruler to ensure that the substrate surface is even to within 5 mm. Do not apply on gypsum substrates with surface moisture of more than 4%. On old or highly absorbent gypsum substrates, apply an initial 2mm course of VALCOL YESO.

For low-absorbency tiles, use VALCOL FLEX or VALCOL SUPERFLEX; it is advisable to apply an initial 2 mm course of VALCOL YESO on the substrate 48 hours before application. Check the product datasheets.

Tile preparation

The tile must be completely clean. Ensure that it is flat.

Characteristics

Mortar made from cement, graded aggregate and organic and inorganic admixtures which improve its workability, water retention, adhesion and anti-slumping properties on gypsum substrates.

Instructions for application

Do not exceed the product's open time. Accordingly, application is recommended in small sections, regularly checking the adhesive's stickiness and ensuring that no film forms on the surface. Re-trowel in the event of surface film formation.

Lay the tile and press firmly to flatten the grooves in the cement.

At all times respect structural, perimeter and intermediate joints as well as grout joints. At least 1.5 mm in indoor applications. Grout 24 hours after application using VALCOL JUNTA UNIVERSAL.

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