acetone cottage cheese

Imagine every Striper told the pavers they work for... "Ya, we will get to it in 30 days" I think the world would actually come to an end...

I use Chlorinated Rubber, and have noticed that my whitest and brightest lines sprayed over fresh asphalt happen when I initially stripe a new line with a light film buildup, followed with a medium to heavy second coat of paint. The light initial coat of paint drys quick enough not to react with the asphalt oils and acts as a barrier to the heavier and longer dwelling or slower drying second coat of paint. Of coarse, this is all good if you were bidding 2 coats of paint, otherwise you have invested the time to stripe everything a second time without getting paid for your labor. As far as paint materials is concerned, 1 heavy coat of paint might be the same amount of material as 2 lighter coats, but the results might be catastrophically different? On the other hand, sometimes the asphalt oils are just going to be to aboundent, fresh, and very soluble, and you are going to get some brown discoloration if you are " REQUESTED TO STRIPE FRESH ASPHALT".

Man O' Man is that a familiar issue! I see 2 coats required on new pavement by the architects often, I bid one coat (because I know all too well from experience that 2 coats will likely cause "curling" on the edges) and then demand the architect signs off on 2 coats, with all kinds of notations that if we do 2 coats the edges will curl and damage the surface. Invariably the architect will refuse to sign, I hand the job to someone else (who unfortunately gives them 2 coats, who they later complain did a bad job....which of course, they didn't). 6 weeks later I'll typically get a call from the very same architect asking for assistance with his specs for future projects (and 6 times out of 10, an architect who insists that we paint his projects from that point forward).

Years ago we had a contract to stripe an airport runway. (small town, it amazes me how many tiny towns have paved runways) The contractor had just finished "fog sealing" the new asphalt and called us in immediately to stripe it. The inspector complained that we were putting the paint down too thin, so we go back over a few areas with more paint and start applying it thicker to the rest. Two weeks later, we start getting phone calls that the paint ruined the surface. Sure enough, it looks like an alligator's back out there. 8"x8" is about the largest size of paint that did not crack. Not only that, but it was like saucers out there, the lips of the cracks picked up over 1/4 inch from the original surface. After a lot of debate that didn't really go anywhere, our company, the prime contractor, and the airport agreed to have a mediator come in and assess the situation. Well, this "impartial" mediator was from an asphalt company, so we were pretty well screwed. This asphalt expert decided it was the paint's fault (surprise surprise) and that we put the paint down too thick. Just as you would expect the inspector promptly forgot any conversation about the paint being too thin. We had to come in and repaint every square inch at our cost. I am very leary of freshly sealed asphalt to this day. Solvent or latex based.

I'm using a air machine, the line gun sprays a great line with acetone but the hand gun which has about 15ft of hose, comes out looking like cottage cheese, i'm guessing that the condensation in the air supply line is mixing with paint. any ideas?

Yes, you got water mixed into the paint. Wash out with thinner and should be fine.

I use a strip of carpet. Absorbs the paint and can be reused many times. Just roll it up and put it away until you need it again. It also works well for an edge against a curb.

We use carpet too.Scraps are free from local carpet store. We use it to stage, set gun height and use it to remove paint from stencils.Just stomp them upside down and keep spraying.
