Ardex V1200

RE: Ardex V1200
K15 is $31 a bag. V1200 is $20 a bag. The difference is the polymers in the K15 which allow it to dry in 16 hours instead of three days.

So when you say the difference in cost is negligible, I have to question if you are thinking from a buyer's point of view or a seller's??? When a bag only covers 2 or 3 square feet at that thickness you can quickly add $4 to $6 per square foot for the product alone.

Both products can do the same job if you work with their differing qualities.

I have added pea gravel to V1200 before also. And K15.
Suffice it to say that there is a lot more to know about levelers than mix the water, pour it out and get paid on Friday. If it was that easy anyone could do it.

RE: Ardex V1200
I just had a Koster quote come in at >$7.30 s/f and the primary reason given for the cost was for 3/8" of K15 on top. Will probably ask for a re-quote using this. Thanks.


What should K55 cost?

RE: Ardex V1200
3/8" is a lot of leveler. I usually put down 3/16". You need an 1/8" minimum for most glues.

A bag of K-15 covers about 44 sf at 3/16" or 22sf at 3/8". If you buy a bag at $31 you have $1.41 per sf cost. Figure 7 cents for primer and 30 cents for labor, some tax and profit and you have a leveling cost of under $2/sf.

Epoxy to handle 99%RH is $1.50/sf. Blast for anywhere between .50 and $1 including edge grinding. Installing epoxy and filling cracks figure .50 cents.

Right now I am quoting complete jobs for between $3.75 and $4.75/sf. Small jobs (less than 3,000sf) between $4.75 and $6.00/sf.

Please note: V1200 doesn't go as far as K15. K15 takes more water in the mix and the bags are 10% bigger. I figure my cost difference between K15 and V1200 is about 20 cents per sf. Not that big of a difference really, but over 30,000 sf it sure can be, and when you need something filled an inch it can be.

RE: Ardex V1200
I have a project where there are 30' long truck docks that have about a 12" drop. They want to level it and turn it into a room.

Any suggestions? I think they need to talk about a full blown concrete pour for that much material.

RE: Ardex V1200
A lot will depend on the intended flooring, current and future moisture levels, timeframe and the depth of their pocketbook.

Even the cheapest self-levelers will run around $1200 per yard of material. Concrete is around $100 per yard.

Gypcrete can be a bit less expensive, but usually cannot be used on grade or where any moisture may be expected.

Concrete is a great product, but if the timeline doesn't allow it to dry you'll have to mitigate it and then self level it. I've done this before and it works well.

Keep in mind you can cut the amount of self levelers you use by adding aggregate.

I usually recommend using regular weight concrete, keeping it clean, then applying an epoxy mitigation system on it and a thin self leveler to give a workable concrete floor again.

RE: Ardex V1200
I just had come down from the 'gods' that we are to stop using K15 and now only V1200. Is it really sandy? How does it feather?

RE: Ardex V1200
Sandier, Yes. Doesn't feather as good as K15, but it works. Compare the per bag cost of each and coverage rates at 1/4".

RE: Ardex V1200
It's sandy. Gritty. Neither is made to feather out, but you can feather them if you catch it right when it is beginning to set up (about 15 minutes after mixing).

I had the opportunity to pour K15 and V1200 side by side finally. Well technically one right after the other. Wink

We ran out of V1200 on a job and had some K15 on the trailer so we finished with that. The difference is quite noticeable. The K15 is creamier and finishes shiny and smooth, where the V1200 is grittier and finishes matt and porous.

The K15 goes much further per bag, and if I am stuck getting a rush order of just a few hundred bags, I'll get the K15. If I can't buy the V1200 at a discount, the K15 is worth the up-charge.

We just poured a small 4500sf job yesterday and used V1200 and were very happy with the results. We stretch the product though... Ardex recommends 1/4" and we put down 3/16". At 1/4" V1200 is a piece of cake to put down and get beautiful results.

I really love Ardex's consistency. It's the same product every day, every bag. No surprises, it just works. I don't like surprises.

RE: Ardex V1200
I had the opportunity to test a self-leveler very similar to V1200 from a newer manufacturer recently. While it was "OK", it didn't spread and finish like Ardex...simple as that. Ya get what ya pay for every time no matter what.

RE: Ardex V1200
Oh man, I had a product I installed by the semi-load. $23 a bag, spread like butter. Level as can be. Wonderful to work with. BIG company. HUGE company.

I loved it until I ended up with more than 2 semi loads of recalled product and the company bailed on me. Exclamation

You'll read about it in the news, I'm not the only one fighting them for damages.

I'm sticking with Ardex. They may not be the biggest, but they're the best.
