Self levelling over ceramic tiles

[andyfr]

I need to level our 2.5 x 1.5m porch so I can lay some Karndean rigid core flooring. The tiles are uneven so I need to get the floor level, what is the best primer and self levelling compound to use for this situation?

The tiles are very well stuck down so I don't really want to take them up.

we had F Ball screed put over our uneven tiles floow in a conservatory - not sure if this will apply to your situation

But that was to put a vinyl over

Thanks, I'll have a look.

Did you use a primer on the tiles?

we had it done by a fitter special mixer for the screed - i think it may have been 1200

Stopgap 1200 | High Performance Smoothing Compound | F Ball

Stopgap 1200 is a fast-drying, high performance smoothing compound suitable for preparing internal subfloors prior to the installation of floorcoverings.

does not need primer and quite settings , so they coul do it in 1 day and then came the next day and laid the vinyl

BUT may NOT be suitable for your application

F-Ball 1200 or Arditex Ardit NA can both be laid over ceramics with no primer as long as they are clean, it’s best to lay two applications rather than trying to level with one thick application.

By the time you have done that, you would be better off laying Karndean Glue Down on high temp adhesive, far more stable than LVP.

Thanks for that. I already have a couple of packs of Karndean Palio core which is why I was thinking of using those. I have put plenty of both Karndean and Amtico glue down but I managed to get the Palio core from eBay as there is just the right amount. Why would glue down be better in this situation?

 

[crazydaze]

Glue down is better in all applications but if you already have the Palio you may as well use it.

Click LVP has an awful reputation for failure in the trade.
