Black limestone nightmare.

[redbubbaboy]

I had a black limestone patio laid last year. Had it sealed and it looked lovely. Then when it rains white marks show up all over it wherever water has sat for a while. Have stripped on sealer and tried various others but all end up the same after rain. What can i do bar taking it up and starting over. Any recommendations appreciated

Do these marks not just rinse off..? and what were they sealed with.?

Hi, no they don't rinse off, sealed with Fila waterproofer and Filawet. Thanks

Fila wet..???. is that a topical sealer..?

 

[redbubbaboy]

Yes, made by Fila an oil and waterproofing sealer.

Ok.. Now topical sealers are not normally advisable for exterior use.. it should say this on the tin/bottle... have a look and pop back.
