(1) Apply adhesive to both tile and substrate for large sizes and/or weights of more than 40 kg/m2.

Supply conditions

25 kg bags protected by plastic sheet.

Mixing instructions

Add approximately 7.25 litres of water per bag of VALCOL FAST (C1FTE). 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 FAST (C1FTE) 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.

Ensure compatability between adhesive and substrate. It should be applied on cement mortar substrates. If applied directly to brick, it is recommendable to apply 5 mm of screeding mortar or cement-based adhesive 48 h before tiling.

Do not apply on gypsum substrates (use VALCOL YESO instead).

For courses > 5 mm, use VALCOL CAPA GRUESA or VALCOL FLEX GRUESA, depending on the absorbency of the tile.

For low-absorbency tiles, use VALCOL CELANIC, VALCOL FLEX or VALCOL SUPERFLEX. Check the product datasheets.


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

Instructions for application

Apply in a single thin layer (on the substrate) or a double layer (on substrate and tile) with a serrated trowel.

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. The grout joints must be at least 1.5 mm in indoor applications and 5 mm in outdoor applications. Grout 3 hours after application using VALCOL FLEX ULTRA. Do not use the product at an ambient temperature below 5ºC or above 35ºC.


VALCOL FAST (C1FTE) is certified by AENOR as conforming to the obligatory quality requirements under the UNE EN 12004 standard.

VALCOL adhesive cement is produced in industrial dry mortar plants with quality assurance systems certified by AENOR in accordance with the UNE EN ISO 9001:2000 standard.

The data is based on trials performed in our control laboratory and is the result of extensive experience with the products made by the Cementos Portland Valderrivas Group. Variations in working conditions on site may lead to changes in performance.


Store in a dry place, protected from frost and direct sunlight. When stored adequately, it may be used for up to 12 months from the date of manufacture.
