Expansion/Contraction of SLC vs. Dry Pack on Concrete

In reading another blurb, a good slurry coat was a good idea on bonding drypack to old crete. Some notions on dealing with expansion, contraction, etc.
Is it due to the fact that drypack by notion, doesn't have any latex in it..

Whereas with SLC, just the manuf. recommended primer and SLC is more than sufficient for a pour right onto concrete --- no slurry coat needed.

Slurry is used when you want to bond the drypack to a slab. ( I usually go with a polymer modified thinset mixed fairly wet). Drypack on its own won't bond too well to concrete. Unless the concrete is very rough and damp.

If you want an unbonded mortar bed go with a cleavage membrane and wire reinforcing and 1 1/4" minimum thickness.


The primer for slc also is a bonding agent and prevents the concrete from sucking the moisture out of the slc too fast.

Two very different products with different requirements.
