Hi folks...

I have a concrete basement and wanted to tile. The concrete was old and fundamentally sound but the surface was a little beat up so I was going to level it out with self-levelling product from LevelQuik... That called for a latex primer of theirs to be put on before the compound; this product: http://www.custombuildingproducts.com/TDS/TDS-234.pdf

My issue arises when I realize that this concrete shouldn't be levelled because it slopes to a drain. So, I decide to use this resurfacing concrete: http://www.sakrete.com/uploads/downloads/Sakrete Flo-Coat Concrete Resurfacer 5-12.pdf

My questions now becomes... Can I put the new compound over the latex primed concrete floor or should I strip the primer somehow and if so, with what? All I wanted was to 'clean' up the original concrete before I tile.. but I keep shooting myself in the foot...

A concrete floor needs to be free of any paint or sealers in order to use a topping,and the primer you used has a sealer in it.

The instructions on the Sakrete product you're thinking of using says;

"DO NOT USE A BONDING AGENT."

Removing the primer won't be easy, plus if I remember you're supposed to apply the patch within 24 hours of the primer, so it should not have been used already. oppps.

I think finding another product made by the same manufacturer, (Custom Building), is the best choice. Don't have an answer right now though.

They did huh...... Well, generally we don't recommend that cuz the solvent gets soaked into the substrate and may become a bond-breaker. How are you gonna remove the film/residue from the concrete?

I just can't win with this project :censored:

Doing some research, I was going to scrape off the residue and give the surface several turns of detergent/water
