ON this thread: Floor Tiling On Concrete - Several Questions About Floor Prep and Laying - https://www.tilersforums.com/threads/floor-tiling-on-concrete-several-questions-about-floor-prep-and-laying.87417/page-2#post-931307

I asked abuit how to level a row of engineering bricks that sit 2 to 3mm below the concrete floor. They are only 4 inches wide so I wasn't going to use a SLC but because I have 1 corner with a very small area that dips I might as well do the bricks and that area with SLC.

I went for

at screwfix. This was £9.99 and the instructions say to use the Eco-T Primer which costs about £30. Is there a more generic primer that will do the job as I'm literally covering a surface area of about 0.5sqm so it seems steep to buy that primer.

I already have Benfer Prim to prime for the tile adhesive - perhaps that would work?

Thanks.

You can use primer that you have got,or SBR, or just clean and dampen area. Best practice to prime.

So I'm about to prime the small area I want to use SLC on. Presumably that'll take 30 mins or an hour to dry off. Then I want to apply the SLC. I gather that will be touch dry in a matter of hours. But it says 24 hours to fully dry.

If I pour that at say 7pm will I be OK to prime and tile over at say 10am tomorrow morning.

If I need to prime the rest of the floor area before tiling tomorrow should I prime it tonight or will it be OK an hour or two before I tile tomorrow? (Its hard to keep cats out of area and they may wee on the floor)
