Grooves

[317 Rider]

I have been reading a lot of post on here in an attempt to gain as much knowledge before I epoxy my floor. My question is do you have to fill the grooves with some sort of fill or can you just apply the epoxy in the grooves with a brush?

Thanks

Alex

By grooves do you mean the expansion joints? If so, you can epoxy them. Though a lot of people prefer to fill it with a joint filler and level out the floor for a even surface.

Don't try to fill the expansion joints with the epoxy - just paint it with a brush.

Next time I do one: I'm going to fill the joints with an appropriate compound first -- that way the joints don't collect dirt, etc.

Those joints in some cases also act a as a water guide. Water will colest in those and drain to the correct location. Filling them up may allow for standing water.

He is talking about expansion joints. These joints provide a stress relief for the concrete and the hope is that any cracks will develop in those cuts.

What you are talking about is saw cuts to channel water, usually because the cement was poured, poorly resulting low places for water to collect. Sometimes sawing the cuts in will help drain the water away, but the reality is that if it was poured properly in the first place, there would be no need for them.
