EPOXY STRIPER

IS THERE ANY SUCH STRIPER MADE TO STRIPE THE TWO PART EPOXY THAT THEY USE ON CONCRETE HIGHWAYS? I'M TALKING ABOU T EPOXY THAT IS MIXED AFTER IT COMES FROM THE TIPS, A TWO GUN TWOPUMP UNIT?

The "epoxy you are talking about is most likely Polyurea. Equipment made to spray it is very complex (check MRL's web site). The material has to be heated, it is mixed at the gun and the hoses going to the gun are also heated. This equipment requires a compressor, large generator and as such is not practicable to be on a portable line spraying unit.

This is the smallest one I've ever seen:

Thank's for the info! It's what i figured but wanted to ask just incase. any good advise on what i could use that would spray through my airless that will get the job done, i hate to pass this one up.?! riley where are you located?

There people on PLP who have successfully sprayed epoxy ( two component ) thru a walk behind. You should be able to search, as for specifics I haven't seen much on it here. I would be well aware of the variables involved with the product and not push the limits of pot life, otherwise I think it can be sprayed relatively easy. I seriously doubt you could get approval to hand mix and spray for a city, state (gov't) spec job using the product the way you would have to with a walk behind, just my two cents though.

riley, who makes the striper in the pic. may be interested in one?

That's a Mark-Rite unit.

Becareful mixing epoxy, as was stated it needs to be heated, to assure the proper mixture of catalist to color. If it is not your line may come out white and then when it dries it will be gray or even black. That is why the equipment is so expensive. Also the small machine that was posted will be low production, when you run out of product and have to add more there is a considerable time to heat the new product. Just what I know.

When we do epoxy floors we have never had to heat up the mix. All we did was put the 55 gallon drums on there side and open the spouts and start mixing. -Dean

The epoxy used for striping is very different than the stuff you would use on a floor. The resin is very viscous and in order to get it to mix properly you would have to heat it to the point where the pot life would be too short to risk running it through a single-pump striper. My experience is with Poly-Carb's epoxy so YMMV with other brands.

What about UV inhibitors? The striping product must have them as part of the mix?

I've done epoxy long line stiping for about 6 years, part of that time with MRL. Riley you are right in that the floor epoxy is in no way the same as the epoxy used in striping. One of the main things that needs to be done with it is put it down with the right mixture. Its put down at 2500 psi also to help with the mixture. The heat helps with getting the right viscosity and to help it cure faster. The cost of the equipment would make most shy away from it. As i believe a full size truck from Mark Rite is around the 500,000 dollar range. I'm not sure what the smaller unit goes for, but im pretty sure it isn't to cheap. Last time i was up at Mark Rite they were still tweaking it also. There aren't many of them around either and i know the owner or Mark Rite has put a lot of money into getting them going. Which in turn would make the few units that are out there that much more expensive. I guess in short i wouldn't bid a epoxy job unless you have someone that know the material to run it. The cost of replacing it if put down wrong well make an easy money job into a big headache.

Thanks yon. i gave up on the job anyway.
