Question: 

I have a crack about 1cm wide down one side of my concrete swimming pool, can you tell me what product I would need to repair it please.

Answer: 

Ensure the area to repair is clean and dry. Prime the bare concrete crack with 405 Tack Primer, and then use 202 Vertical Surface Repair Mortar to make good. Once cured, this can be overcoated with most single or two-pack swimming pool paints.

questions peter howard on 18/06/2015
Question: 

My swimming pool is leaking - I think the wall behind the mosaic tiling is porous. What Sika product would you recommend?

Answer: 

All tiles and existing render should be removed and then the Sika 1 Waterproofing System should be applied. This is a 3 coat system using Sika 1 Spritz and Bonding Coat Mortar, Sika 1 Render Mortar and Sika 1 Finishing Mortar. Once applied this system can then be over tiled to bring the pool back to the desired appearance. Alternatively, if you wish to try a less disruptive solution first to see if the problem can be dealt with by using a waterproof coating you could prepare the existing tiles by thoroughly cleaning them and abrading to provide an adequate ‘key’ for the coating to adhere to and apply 2 coats of Rust-Oleum 5500 Solvent Free Epoxy @ 6m² per litre/per coat.
