Greetings,
I have an old brick Cattle watering tank on my land. Dimensions 4x1x1m
It was previously patched with cement, which has now blown out. I plain to knock the cement off, and re-point the bricks with lime mortar.
I’d like to use the tank as a dipping pool/garden-water storage tank, so I’m planning to seal the inside with natural Prompt cement.
Should I mix the Prompt with sand as well as water to form a good spreading render?
Any advice welcome.
Hi, thanks for getting in touch. We would suggest that you mix 1 part Prompt to 1 part Sand or 2 parts Prompt to 1 part sand to create a waterproof material. You willl need to add a cap full of tempo per mix to help slow the set. For mixing purposes start by mixing water with sand and tempo, the introduce Prompt to the mix. I hope that helps. Don’t hesitate to get in touch if we can help further.
