Forum Title: Grinding before self-leveling
Hi, I am new to floor work. I am going to self-level my basement concrete floor before putting Barricade subfloor tongue and groove panels and luxury vinyl on top of that. I looked at Mapei or Sika self leveler compounds and both manufacturers say to grind the floor to CSP #3 profile. I renter Husqvara PG280 single head grinder to do the job. As I can't really tell what's CSP #3 vs #4 etc I can't definitely say whether the floor has been ground to the appropriate level of roughness. My question to the knowledgeable folks here is this - how crucial is it to have cement ground exactly to the level that the manufacturer of the self leveler recommends? What can potentially happen if the floor is not sufficiently ground or not ground? I am applying self-leveler across the entire surface. THank you much in advance.

A diamond head is sufficient.

Thanks, Ernesto. But what can possible happen if the underlying slab is not sufficiently ground? Will self leveling underlay crack under foot traffic? Ernesto said: ? A diamond head is sufficient. to expand...
