Back in a post from 2005, I read where Lindy was discussing the "Lexus" of new sealers, which were apparently still in R&D at the time. Any word on their availability now-any experience with these that anyone might want to share? We have been using Decosup HBright solvent based but getting concerned over the vapors. I will say that it is one good sealer though... Thanks all. Love this board!!

Polyaspartic Aliphatic Polyurea have proven themselves to be through ASTM tests, as well as application on interior flooring (industrial/commercial) and exterior decorative concrete surfaces subjected to the harsh elements of Mother Nature and vechile traffic to provide above and beyond typical alternatives in relation to wear/abrasion resistance and superoir longevity/performance.
They are usually applied using a roller; however, can also be applied using an airless sprayer (13,000 to 15,000 tip). Many concrete countertop contractors apply using HVLP equipment with a lacquer tip.
Other sought after features/benefits (being manufacturer specific to my brand; a website Sponsor; GoldenLook/Diamond Shield) are: (1) ability to cure out in temperatures as low as -30F (minus 30f), (2) 1/8 mandrel bend, allowing it to flex with substrate, (3) can be applied up to 10 mils in one coat without outgasing/pinhead bubbles (most sealers must be applied in thin/uniform coats of not more than 1-2 mils; failure to do so bringing about pinhead bubbles and various other defects), (5) ability to remain glass/water clear indoors or outdoors, (6) quick dry, 2 hours to recoat, recommend 2 coats, 4 hours return to service, no need to ever apply sacrificial coats of wax to protect or prolong life of sealer, (7) meets sanitary surfacing criteria of USDA/FDA, (8) non-hazardous classification, saving on freight charges as well as being more applicator friendly, (9) available in high gloss and satin finishes, (10) brings out color vibrancy on various decorative concrete surfaces, (11) etc/etc.
If you would like detailed information, technical data/specifications, complete application guidelines, etc. please drop me a private message or send me an email forlynn@texasinternet.com or lynn@goldenlook.com and I will promptly put it in your hands.

Not sure about the polyaspartic Lindy was referring to but the one I use has almost no odor at all. Very easy to use indoors.

Applied on indoor surfaces as frequently as exterior. Is VOC compliant and shipped as non-hazardous material (class 55). VOC's are 2.8 lb/gal (this being combined resin and cure content). As with any sealer (with exception of water based/solvent free formulations) ventilation is recommended/necessary during application/cure out; however, this sealer (Diamond Shield) dry's rapidly (average 2 hours 1st coat, 2 hours 2nd coat, 4 hours return to service). When dry low order ceases to be emitted. Note: odor is substantially less than any solvent based acrylic or aliphatic moisture cured urethane, with these types of sealers also being considered toxic, comtamitive, flammable, and hazardous to use and ship.

Here is a link to some information on DecoShine, a rollable polyurea sealer we manufacture.

I called Decosup about this product and about sealer last week. Each time I get a guy on the phone that sounds like he just woke up. I asked him about the Decoshine product and after every question he would put the phone down and then take 2 or 3 minutes to get back to me. I asked if you could put down 10mil coats and he did not know. He said it was watery like a solvent sealer? After the 4th question and waiting 4 minutes I just hung up the phone. I thought the price of this stuff had gone down but he quoted me 200$ for the.
What are prices for the 2 gallon kits from other suppliers? I bought from flex-mar 1 1/2 years ago I think it was 260$ for 2 gallon kit.

Just as you pay more for Lexus than a Ford, the value of one is longer lasting than the other. Polyaspartic Aliphatic Polyureas (PAP) have proven their superior physical properties for over 5 years now.
Price is relevant to longevity/performance. Average price for high performance, commercial/industrial, custom formulations of PAP's is about $135 to $140 per gallon (1-1 mix ratio, packaged in 2 gallon units). This works out to be approximately $.80 to $.85 per sq.ft. (based on a two coat application). Typical coverage: 1st coat = 225-250 per sq.ft per gallon.; 2nd coat = 350-400 sq.ft. per gallon.
There is no need to apply sacrificial coats of wax on a PAP sealer (this saves time, money, and loss of use when doing so). It is an unfortunate fact that residential or commercial property owners start out keeping their floor waxed to extend the life of the sealer; however, this is sort of like a new car in that for the first year the owner waxes it frequently, but after the new wears off they procrastinate to the point that they don't do so at all anymore then complain about the results of their routine cleaning/maintenance failure.
With the cost of gas being highway robbery, the number of trips to a job cuts into profit margins. Since each of 2 coats of PAP dries within about 2 hours, with return to service in 4 hours (along with no need to come back and wax the sealed sure), you can complete the sealing of surface in 1 day and return it to the service of the property owner in record time.
The above are but a few of the reasons that an investment in a PAP sealer on surfaces pays for itself ... you make less trips to the job, customer has higher/longer performing sealer, return to service is rapid, no need to ever wax, and the physcial properties associated with PAP's far exceed those of all other sealers.

tshampoe, you spoke with the janitor, he sometimes answers the phone after hours and plays jokes on people, no, not really, I apologize for this but being a new product not all of our office people can give technical advise, if you still need info feel free to call me directly.

if a polyurea has no odor, the fumes won't kill you but the pot life will. you'll have 15 to 20 minutes to spread it out before it starts gelling up.
most if not all polyureas would not be considered "rollable". unless you want to mix one gallon at a time. even the ones with a lot of solvent added in still only give you a half hour.
they are good durable sealers. but no fumes or vapors is not one of the benefits. the primary advantages are durability, high build in a single application, and uv resistance.
but you really need a crew to apply them. one guy to mix, one to spread with a squeegee, and one guy to backroll.
if you want a rollable sealer, stick with acrylics or water-based epoxies and urethanes.

Traditional polyurea's are tough to roll and have short pot life. But not poly-aspartic. I have used a half dozen different ones and the pot-life averages about an hour and rolls out like a dream

I want to hear more about a polyaspartic with an hour pot life!!! I have never heard of that.

you haven't heard of it because it doesn't exist.
bayer is the primary supplier of polyaspartics resin and hardener to decorative concrete product manufacturers. they've done a lot of research and development on this.
last i checked they had systems set up with 3 different pot lives: 10 minutes, 20 minutes, and 30 minutes. if you go any longer than that you've got to add a lot of solvent and it affects the integrity of the sealer technology.
high film build in a single application means using primarily resin technology and little solvent and having the material set up before it can level out too much.
if you want a longer pot life, that's fine, but you've got to use a different product and build the coating in thinner applications.

If you want a real polyaspartic, thats not water thin, not full of solvents, check this out.
We have all the tech support you could want, 30 years combined epoxy use, 15 years spray poly experience, and tons and tons of polyaspartic jobs complete with zero callbacks or complaints.
There are so many solvent loaded polyaspartics, that are water thin its insane. I have seen so called 'apliphatic' polys, that yellow and fade within a year. There are good products, and bad products, find the differance.

By the way, we have a 2 hour cure 75% thats awesome, there is one solvent to cut it back, which does not register as a harmful VOC. The 75 is VOC compliant for use in California, and our 100% poly has zero VOC's.
After all the companys i have researched, or used, nobody has these qualities.... i dont know why. Check it out.

We have been using Polyaspartics for a while now as well. Benefits: low odor and very durable. Downfalls: very short pot-life and working time... you have got to be on your A game with everyone on quad shots before trying it on a large floor. One thing I haven't been able to figure out yet is if there is anyway to get it in a satin finish. Every product I have seen or used has only been in high gloss (liquid clear). Anyone heard of this stuff being available in satin?
