What concrete do I use for resurfacing a interior floor?
 
I've pulled up the carpet and laminate from my dining room and kitchen, and the concrete slab underneath is uneven and has gaps about 1" in certain sections.

I want to lay down a coat of stain and epoxy over the entire floor.

So what type of concrete mix do I need to lay down onto the existing to get it leveled out and ready to apply the stain and epoxy?

Thanks all!

I am not an expert in this field, but years ago I had success using vinyl concrete patcher & then painted the floor with a low gloss latex. Others on here may have better suggestions.

You'll want to use a polymer modified cement. It's what all the decorative concrete contractors use for the type of overlays your describing. There are a bunch of manufacturers so here's a link:

i've been reading on the polymer modified cement on the decorative concrete websites...
It looks like there are 2 ways to do this.
1. use the existing slab, spray a stain on it and roll or spray an epoxy coating over it so that it makes the top strong for foot traffic.
2. they have a 1/16" thin layer of epoxy style cement... which apparently does the same thing as #1

Other then that I can't seem to find any more info on it other then finding contractors to actually come out and do it.

So, from this info i've come up with this procedure.
1. Use a Sand/Topping mix like this: http://www.lowes.com/pd_10389-286-11...uantity_sold|1
2. After a couple of days of curing, spray a stain on the top of it.
3. After a couple more days of the stain drying, spray the epoxy top coat on.

So, with this, I have a couple more questions.
1. I removed the existing floor and there was old tile directly onto the concrete slab. I chipped it all off but there is a old tar like adhesive left on the concrete. Is there a type of cleaner to remove this old adhesive? Or will pouring a bonder on it then the Sand/Topping mixture be good to go?

2. Am I suppose to be using a Trowel or a Float when putting this Sand/Topping mix on?

I'm going to guess that you have an older home. Mine has tiles over tar over concrete.
You might want to leave the tar/tiles in place, not only can they be a major pain to remove, the tiles might be asbestos.

What type of floor are you looking to put down? I'm looking at solid hard wood and I'm probably going with a floater system (2x4's pressure treated on side 16" OC) I think their called floaters or streamers, then 3/4" plywood over that.

The tar and tiles you have on there now will work as a moisture barrier.

As far as making level, you can shim up the floater system, the down side of the floater system is that you'll have higher floor height, probably 2".

If you're doing tile, a floater system should work as well, I think the difference is what is over the floaters, maybe concrete backer board.

Yes it is an older home. Well wether for not the tiles are asbostes or not... I already chipped them all up and only the tar is left. I wear a mold mask when I do all of this anyway.

I actually WANT to do a concrete stain on the whole thing instead of a tile or wood floor.

You are headed for trouble my friend.

Sand topping mix is in no way tuff enough for this purpose.

You need a polymer modified self levelling compound. You can find these on the "Mapei International" website. There are others.:)

The SLC you use must be rated for "wear surface" use.

Integraoligist 02-08-2011 11:30 PM

ok, I found this SLC at the home depot website:
http://www.homedepot.com/webapp/wcs/...82&R=100192482

It does not say anything about a wear surface... of polymers. But a couple of the reviewers have poured this and put epoxy over it with success.

It's much more expensive then a standard concrete.

Other then this I can't seem to find any other SLC anywhere local.

Is this what I should be getting?

Integraoligist 02-09-2011 03:59 PM

I also found this at Menards:
http://www.akonallc.com/residential/...erlayment.html
Still it does not say anything about polymer modified or wear surface.
Thoughts?

Bud Cline 02-09-2011 05:01 PM

The Level Quick IS NOT intended for use as a wear surface, it is an underlayment for additional floor coverings. All products have a "Data Sheet" available. If you were to look up Level Quick's Data Sheet you would find:


Quote:

LIMITATIONS

Do not use over lightweight concrete, gypsum
underlayment, OSB, particle board, hardwood floors,
parquet floors, or metal.


Do not use when the temperature is below 50 F (10 C)
or on sloped surfaces that require drainage.

Not meant for use as a wear surface.

Same deal with the Akona.

What you are wanting to do is going to require a little effort. You will have to order the proper product, it isn't something that is routinely stocked at a home center. It isn't like buying a loaf of bread. Self Levellers used for a wear surface are specialty items and taking the path of least resistance isn't going to benefit you at all.:)

Integraoligist 02-09-2011 06:18 PM

Ahh ok, I got you know.

I was able to find this online, they ship direct. It's $36.50 a bag for a 1/4" thick 25 sq. ft. It's the 5500 version.

I also called and talked with Quikrete and they have this:
http://www.quikrete.com/PDFs/SPEC_DA...Resurfacer.pdf

It says it is a wearable surface but nothing about any polymers in it.

The lady at Quikrete said this is what is used for interior flooring for staining or epoxy finishes.

Bud Cline 02-09-2011 07:19 PM

OK Slow Down.

Ordering that product on the Internet is going to break the bank. That is the correct product but my suggestion is that you find a local tile store that will order it for you. You don't have to use that brand. More readily available brands would be Mapei or Ardex and any tile store will have access to those brands.

How much square footage area are you trying to cover? Let's see what you really need.

A typical 50# bag will cover 50 square feet at 1/8" thick. If you are going to use the recommended mesh then things begin to change. It takes a minimum of 3/8" thickness to cover the mat but the mat also occupies space so there is some calculating involved.

The thing to do is have it shipped in in pallet form not UPS or FedEx one bag at a time - that would be crazy.:) You can probably move a pallet for about $45 in most cases.

I called up Lowes to see if they carry the Quikrete, they do not have it in store... and it was to late to call the place they get it from so they are suppose to call me back in the morning on wether or not they can get it.

To start off with, the little "step" of concrete that I currently have f'ing up my floor i'm going to chip away at to get it a bit lower with everything else on the floor...

I was going to grab come patch concrete to get that somewhat flat and to fill in a 4" wide by 4" deep hole that is in the floor. When I asked Quikrete about that she said to wait 5 days after I fill in those sections before putting the resurfacer on.

I'll let you know what Lowes says tomorrow and if they can't get it then i'll call a few tile places and see if what they can do. Menards is always the cheapest on everything they sell as compared to Lowes and Home Depot but the people there just dont care and are no help. So I may have to go there to see what brands they carry then look it up and call the manufacturer to see if Menards can get it.

I would rather get this stuff from one of these stores so that I can order Extra just in case, and take back what i dont use (hopefully).

Integraoligist 02-09-2011 08:09 PM

i'm going to recalculate my area tonight to get an exact sq. ft. that I need.
