I assume you are proposing to use it as an additive for brick mortar? I have no knowledge of it for this application I am afraid. **Q: Can I use this on the back of 20mm porclain garden tiles** A: Yes. It is ideal for creating a slurry with cement applied with a brush to the back of a 20 mm ceramic tile. It is a water proof when dry bridging agent. **Q: Would this product work as an exterior treatment to stabilise 100 year old flaking/weathered sandstone blocks?** A: Watered down it may work as a seal but it is intended to bond other materials not just seal one, it may also leave an unwanted sheen. I think there would be a better alternative out there. **Q: Will it bond to exterior if painted for rerendering?** A: This would depend on the paint application, however, we would advise to remove the paint prior to any render application. ## Customer Reviews ### ⭐⭐⭐⭐⭐ SBR ever build *by R***N on 24 July 2022* Great Product Excellent Customer Service Would Recommend This Company ### ⭐⭐⭐⭐⭐ Good value @ £64.40 for 25l *by A***S on 13 April 2022* I always use this to prime walls for rendering ### ⭐⭐⭐⭐⭐ Great product. *by R***S on 11 March 2019* Used about 3 tins of this before rendering my house.Also added it to the mix.
