I have a patio around my pool that has large flat rocks on top.
Several of the rocks have worked themselves loose. What should I use
to re-attach the rocks? Someone told me to get the stuff masons use
to attach the top layer of stones in a stone wall but I didn't see
anything like that at Home Depot. Is it just regular quick-create or
is something else advisable?
Not sure about this, so listen well to others, but if rocks are attached to
concrete base, thinset mortar may work. Be sure to dampen both the rock and
the base first, then brush on a thin paste of pure portland cement powder as
a prime, then immediately trowel on enough thinset mortar (it may be called
thinset cement) to level the rock with the surrounding slabs.
Alternatively, you can prime with something that looks and smells like white
wood glue, that is used for helping patching-cement bond to old cement, and
stones. Tap home, using a rubber mallet and/or gentle mashing with your
feet. Cover stone with a damp towel to keep area moist while setting.
Personally I don't like this construction, I like dry lay.
However for a quick fix, I suggest looking in the concrete area of your
DIY store and find a tube of adhesive made for this use. It comes in one of
the tubes designed for a caulking gun. Ask if you don't see it.
