Filling in saw lines in concrete?

[Lyaec350]

I did a search but there doesnt seem to be much similar to my situation. I'm sick of the saw cuts in my garage floor (1/8" wide and ~3/4" deep) getting filled with dust, sand, sweeping compound, etc.

What can I do to fill them in? I picked up 12 tubes of Cement Crack Sealer (normally $3.96, clearance for $0.82) will this work?

I couldn't find any weatherstripping tube stuff that was small enough to jam in to a 1/8" crack but I suppose I could check other stores. I think 12 tubes should be able to fill up those cracks pretty well.

Ok, I was hoping to avoid the mess of masking etc etc and just use a caulk gun and wipe it w/ a finger or card when done. The cracks are really narrow and shouldn't take too much material to do.

here is the best there is, its self leveling which is what you need.
No need in using the finger just a caulk gun.
Sika brand

and here is the technical data

I have given Sika links out here to use for many concrete fixes, just to let folks know I dont work for them, I have just used a ton of their products and have never been disatisfied with them.

If I try a patch and it doesnt look good can I just scrape it out like silicone or does it bond to the concrete?

 

[dumbandhappy]

well I would guess it would depend on how good the patch is, with the Sika polyurathane you might be able to get it out but it wont be easy, it really boonds well unless there is a lot of dust and dirt in the cracks when you apply it.

After you patch it with what ever you use you might want to top coat the entire area with a concrete resurfacer which may hide it all. Here is a link to what Im talking about

I used NP1 by Sonneborn in 1987 and it still looks great. It comes in caulk tubes and is available in several colors. I first saw it used on sidewalk joints. Bill

I filled mine in 20 years ago and they are still great. Just used light grey acrylic latex caulking made by Dapp. It's called Alex Plus now. Costs about $2.00 for a 300ml tube and I doubt it took more than a half dozen tubes to do my entire 2 car garage. I wash the floor occasionally with the power washer and it's never come out.

Alex Plus has a 20 year warranty, lets hope for you it last longer but it is a great product especially for $2.00 a tube.

I think what might need to be asked of the poster is do you jsut want to fill in the sawlines or do you also want to cover up the sawlines as well ? Your floor of course will still have the sawline look if you just fill in or patch with what ever product you choose.

I had 310 feet of saw cuts in my garage (2000 sq ft). The floor had been down about three years before I got around to doing an epoxy floor. I used a foam filler rod first. The filler rod was probably 3/8 inch, but it goes in a 1/8 inch saw cut using a putty knife. I then filled the saw cuts with a rustoleum crack filler. After the epoxy hardened, I sanded it smooth using a 7 inch grinder with 80 grit sandpaper. The saw cuts are invisible under the epoxy and I am very happy with the outcome.

That's EXACTLY what I'm going to do with mine this summer - thanks!

this sounds like a good idea, how flexible is the crack sealer stuff is it like epoxy (semi flexible) or does it just set up rock hard?

The rustoleum crack filler does harden like epoxy (it is epoxy). I did this last fall - so far so good, no cracks. The rustoleum crack filler was available at Menards.
