Is CTA Flexible suitable for a swimming pool?
Yes. It is fully waterproof and frost resistant, so it is suitable for swimming pools, wet rooms and exterior tiling, unlike the ready-mixed paste adhesives.
Can I fix porcelain with it?
Yes, it is ideal for porcelain and other low-porosity tiles, on floors and walls. The white colour also stops trowel marks grinning through light tiles.
Can I use it outside?
Yes. It is rated for interior and exterior use and resists frost once set.
Is it suitable for underfloor heating?
Yes. As a flexible C2 adhesive it copes with underfloor heating and backgrounds subject to limited movement or vibration.
How is it different from Rapid-Flex?
Both are flexible C2 adhesives. CTA Flexible is fully waterproof and frost resistant for pools and exterior work, with a regular set. Rapid-Flex is the rapid-setting option when you need light traffic in 2 to 3 hours. Choose by whether you need waterproofing or speed.
Why choose white over a grey adhesive?
White does not show through light-coloured or translucent tiles and glass mosaics, where a grey bed can grin through and spoil the finish.
Can I tile over existing tiles?
Yes, it is suitable for tile-on-tile work on a sound, clean existing tiled surface.
