Does latex plan need priming ?? - TilersForums.com

[poynton phil]

Levelled a concrete floor with latex plan, i'm putting ceramic tiles on it, the customer as bought Mapei rapid set adhesive, i dont know weather you need to
prime or not, i know there is no need to prime if using keraquick, on latex plan, but not to sure about this adhesive. Any advice is appreciated. Thanks.

I would prime the slc before fixing tiles

To be honest, I would always prime an absorbent subfloor, unless I'm specifically told/instructed not to by the manufacturer, for peace of mind, and ease of working (i.e. extra working time with the trowelled adhesive)
