Frequently Asked Questions about Cementitious Adhesives
How much mix do I need per m² ?
For a 60 × 60 cm tile with a 10 mm trowel, the average consumption is 3.5-4.5 kg of adhesive per m². The XXL format or irregular substrates increase the quantity.
Is it mandatory to prime the substrate?
Depending on the conditions, a suitable primer prevents premature drying on highly absorbent substrates (plaster, drywall) and improves adhesion on smooth surfaces such as old tile.
Can I use it in extreme temperatures?
Always work between +5 °C and +35 °C. Below or above, setting slows down or accelerates and the bond may be compromised.
When is it possible to rejoin?
Under normal conditions, 24 hours after placement.
Are Colcret adhesives suitable for underfloor heating?
Yes. The Flex and Flex Premium components are flexible and accommodate the system’s expansion.
