DAGS - maybe I'm not hitting the right search terms.
Shop is in the garage - and there are those expansion (?contraction?) joints
in the floor. Before I paint the floor, I'd like to try to fill the joint
with something to make the floor flatter and tools easier to roll.
Any recommendations on a product/brand name?
When I had the basement finished - the contractor applied something down
there before the carpet / pad was put down, but I never got look at what he
Here's a few links of you.
Look at the Concrete-Fix-All
I have used all of these products with great results.
I filled my expansion joints by stuffing an appropriately sized foam backer
rod into them - about 3/8" down, running the full length of the joint, then
just running a bead of caulk. It worked just fine, and was dirt cheap.
Check with your paint manufacturer. I got some epoxy paint
and I believe, I haven't checked, tells me what to do for
joint coverage. You want to make sure that whatever you're
using is compatible with the paint.
Check their website, it might help.
I didn't see any mention of how big the slots are but if you're
talking about those 1/4" crack stoppers just paint the floor first and
then fill them with your choice of something in a caulking gun. Butyl
rubber would be my choice but dont get any on ya.
The reason for painting first is that, IME, butyl rubber, latex
caulking and RTV will all eventually lose their grab if applied direct
to the concrete.
If you mean something wider than 1/4", just rip some scrap lumber to
size and lay it in. You dont need a lotta strength unless the joints
are really wide. Paint over it and you're done.
Other things that would work would be thinset, plaster of paris and
Ardex. This last is a thin, pourable, self-leveling compound for
building up floors, but it would work well in this situation.
Expensive tho, $38 for a 55# bag that will do 10 sq ft to a depth of
1/4". Google 'ardex' for more info. The company can locate dealers
