Steve Last Posted September 6, 2006 Share Posted September 6, 2006 I believe there is a self-levelling or similar compound formulated for existing tile floors for use when one can't lift the old ones and wants to tile over them. Does anyone know what it's called? Steve Link to comment Share on other sites More sharing options...
chris pp Posted September 6, 2006 Share Posted September 6, 2006 If your existing tiled floor is sound and reasonably level there shouldn't be any need for self levelling products, Steve. Simply give them a clean and use a good quality flexible tile adhesive (Fermaflex Pro for example) and tile directly on top.Chris Link to comment Share on other sites More sharing options...
Chancer Posted September 7, 2006 Share Posted September 7, 2006 If your old floor is not sound then for belt and braces security first clean with a neat or dilute solution of hydrochloric acid followed by a "primaire d'accrochage" and if the old surface is not reasonably level (like mine which was laid on a bed of sand) then use a "ragreage autolissant".The primaire d'accrochage is also recommended if laying tiles or ragreage on top of green concrete.A great tip for grouting is to mix it very wet, spread it around with a raclette, relax with a beer for 45 mins - 1 hour and then pour sawdust on top, finally sweep up with a fine but stiff broom. No cleaning needed and leaves the joints looking perfect. Link to comment Share on other sites More sharing options...
Steve Last Posted September 8, 2006 Author Share Posted September 8, 2006 thanks for the suggestions - the old floor is sound but 15 cm sq terracotta tiles and not 100% flat, the new tiles are 30 cm and I've found that when just put on top dry to check layout, they rattle a bit. I think the cement should take care of it, but might try something else like the "ragreage autolissant". as well. Thanks again. Link to comment Share on other sites More sharing options...
