Hi all,
Was looking for some advice in regards to micro-cracks appearing on the SLC on top of the Wunda rapid response system that was put down. The boards were primed twice with Mapei Eco Grip Plus before Mapei renovation screed 3240 was poured on top. The cracks appeared after 2-3 days of drying and there has been light footfall over the areas.
The subfloor is a mixture of concrete and suspended tongue and groove floorboards and plan to have 10mm porcelain tiles laid on top with either of 2 methods:
1. decoupling membrane and S1 adhesive
2. S2 adhesive only
Are the cracks anything to be worried about and which method would be best to tile on top of the floor?
