ON this thread: Floor Tiling On Concrete - Several Questions About Floor Prep and Laying - https://www.tilersforums.co.uk/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 MAPEI ULTIMATE LEVELLER 1210 SELF-LEVELLING FLOOR COMPOUND 20KG 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.
