I think $500 was cheap compared to any other reasonable alternative -- looks like the same model I saw a couple of weeks ago.

If you pour with fibergalss, you will not be able to lay on it as the fibergalss whiskers will be poking up. Also it will be very rough on the cats paws.

I have fiberglass in my concrete mix and a year later, I can't find any of them on the surface. There were a very few of them there in the beginning, but they rapidly broke off and were not a problem. I guess that if you go looking for them in the corners, you might be able to find a few, but that is rare. The floor was finished with a power trowel to a vrey smooth finish and that might be what made the difference. In the apron that has a broom finish, I still can see some fibers, but they don't hurt anything. Unless he will be working on the floor nude without a creeper, I don't think that any residual fiberglass is going to be a problem. In the event that he is working on the floor nude, then I don't think the fibers are going to be the only obstacle to getting done what ever the job is, the cold and dampness is. /forums/images/graemlins/grin.gif

ouch is all I can say!

I'm wanting to have the fibers in my slab due this summer as I'm also putting in underfloor radiant heat and as such I don't awnt to CUT it. this will help keep the cracks (if any) from getting worse but may not prevent them 100%. I also will coat the floor with a good epoxy coating after a year cure. I think if you coat it too soon it will peal up, as I've seen this happen in other places, you still have to use a good roughing up on the floor using some muratic acid. but the concrete will dry fast after cleaning it. and then coating it a day or so later.

I have plastic under all my floors and they are all under cover (garage, cellar,etc) so I coated them as soon as the concrete contractor was gone. I used a concrete coating that I poured onto the surface and then rolled out with a paint roller with a long handle. I kept working the material into the floor till I had a even coating as best as I could. In some areas it is a little heavier than in others, but it isn't "pooled" in any places. I have no cracks and it has been 3 years now. I believe that the sealer has kept the moisture in for a better cure time. My problem was that if I waited, I knew that it would get dirty with things being moved in out of the garage. If I spill anything it wipes up quickly and the floor repels water well. The only time it is slippery is if there is a pile of snow on the floor. In the winter, I put down cardboard to absorb the water off the car or tractor...

Coating the fresh concrete slab floor seems like a smart idea. Any particular kind or brand that you can remember?

( Coating the fresh concrete slab floor seems like a smart idea. Any particular kind or brand that you can remember? )

Of course I can remember.... it was 3 years ago.... it is thing that happened yesterday that I have problems remembering. /forums/images/graemlins/grin.gif The product is called Drylok Concrete Protector. Here is the web page. I used a long nap roller and just kept going over the floor. If I were to do it over again, I think that I would make sure that I had better lighting than I did. The contractor finished up late and I wanted to get the sealer on before it got dark, so I started about 4 in the after noon. It was already too dark in the garage to see where it was not evenly coated, but it hasn't caused any problems. Besides, now that the garage is filled with junk, you can't see the floor anyway. /forums/images/graemlins/blush.gif

Is it actually fiberglass? Locally polypropylene fiber is used.

For all I know it could be silk thread. /forums/images/graemlins/grin.gif That is what the concrete plant telephone operator told me and being the guilable guy that I am, I just took his word for it. Now, which one is better and which one is stronger? For that matter, is fiberglass even used in concrete?
