2 ? Paint and lifting arrows.

I have been reading all the topics on the types of paints and what some of you pro's use. I rarely paint any lot over 100 stalls. The type of paint that I have been using is SW setfast TM226 white and set fast TM2161 lead free yellow, latex. I live in Western PA. I was thinking and am hoping to get some expert opinions on this. I was going to use SW hot line for all my jobs, unless otherwise directed differently by the client. For the lot sizes that I do what would someone recommend as a set type of paint to use. Second ? I painted some arrows for a local trucking Co. Cleaned surface with a degreaser, but entire arrow lifted. What can I use to clean the concrete better to get adhesion. Had lots of oil and diesel fuel an this location, or should i use a oil base paint for these arrows.

I need to submit an estimate for a helipad at our local hospital, just not real sure how to figure it out. It includes a 1 foot wide stripe around a 54 foot perimeter. Also a cross, 30 ft by 30 ft. and 10 feet wide. And a 10 foot by 7 foot letter "H". Any suggestions will be much appreciated. It looks to me like there will be quite a bit of masking involved. If this isn't enough information, I can scan the blueprint. THANKS!

The few I've done all are basically the same. But, all have been a tad different. However, all were beaded. I think if you would convert everything to a "square foot" basis it would be easier to price. Come up with a cost per square foot and stick to it. .75 to a dollar a square foot would be my range. Make sure you get your "small job minimum" in case all you have is just the "H".

My thoughts are, you are going to need to pressure wash with hot water (and maybe even a little detergent). Then, use an alkyd paint. Should solve the problem.

Replacing parts and tuning up three graco line striper's. I can order the suction hose through a graco dealer, they are not cheap! We went to; two industrial hose suppliers and they do not stock this special hose. It has a liner on the inside so paint will not dry on the inside. Any ideas on where I can purchase this hose in larger lengths and hopefully cheaper.

So, how does the "special" liner keep the paint from drying? Sounds like propaganda. A hose is ahose. No special liner in the Speeflos. Hmmmmm......

It's got a Teflon liner. I found out when I cut the leaking end off one and tried to force it back onto the tube, The inner lining separated and blocked the suction. had to bite the bullet and buy a new one.

I have bought and used other hose successfully, get chemical compatible hose and within the last couple weeks I put Goodyear 3/4" ID fuel hose on a Graco gm3500. The better chemical hose was approx 4.5 per foot and the fuel hose was 11.60 for 10'.

Ross is right! The Goodyear Fuel hose should do just fine. It's inner liner is probably nitril which is resistant to fuels. It may however, break down when exposed to straight Naptha or Methyl Ethyl Keytone (MEK) but mineral spirits should not harm it. As for the inner liner on a Graco hose being Teflon, it is probably for chemical reisstance reasons rather than paint adhesion (although that might be a plus). Lets see, the last time I cleaned or needed to clean my suction hose was - - - NEVER

I was told by my repair place that the hose are hydraulic hose you can buy. The liner prevents the paint from sticking. And yes titans have them same type of hose. Jim

Do you have to paint the inside of the circle white? The Last one i did we had to paint the inside of the circle white (2 coats) and then the "H" had to be red if i remember right. I would add on a few bucks if you have to use any colors you do not normally use. But Stripes idea about Sq. Ft. does make it easier. And what ever you do TAPE OUT THE "H"!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Yes, all have been white backgrounds. You might want to suggest to your customer to use something different other than just traffic marking paint i.e. industrial enamel or at least a concrete sealer over alkyd to allow easier clean-up from those "messy" loads and unloads. You'll need to evaluate drying time if you use industrial enamel ... considerably longer. The last time I did one, the pilot came out and moved the helo over the fence and landed it on the grass..... pretty cool. Make sure you have all the superfluous materials battened down! Anything less than the weight of a concrete block will get blown away!. I use straight edges instead of tape on the "H". Whatever is easier for you is the best way.

I might try two approaches on your arrow; scarifier (grinder) and hot water pressure wash with degresser allowed to soak. Chorinated Rubber should be a good paint for this area once clean

You defo need a chemical compatable hose, just last week I replaced a suction hose with another thick rubber sort of hose and I had left the machine on thinners over night just to give it a good clean out, which I've done loads of times, the next day I came to clean the machine and the inner part of the tube had crumbled and broken down, I had to clean out all the rubber bits out of the machine, I went to a hydraulic hose fitting company and they looked up the right hose for me against the paints and thinners I used.

Thanks for the input. It's all helpful. The hose is still in good shape. I want to replace the hoses because of the sponginess where it connects to the bottom of the pump. We may be pushing our luck on a tear or blowout.

Shows to go ya how much I don't know. However, I've been using plain old hydraulic hoses on my white machine (high side) for years. I'd be for cutting off the defective part of the suction if you hve enough hose to allow. Not much chance of a blow out if it is on the suction side.

Hank, If you have enough hose length just cut off an inch or two and reattach. "Hose is NOT hose", The lined hose choice is to eliminate the reasons Wendy had a failure. Poorly selected hose can soften, dry out, collapse, swell, crack, degrade, and disintigrate just to name a few. The liner is not Teflon due to the extremely high cost of Teflon and the chemical resistance of Teflon would be overkill. Line hose has been used in the striping industry long most of us every striped our first lot. All air spray hose has been and is still lined hose. Airless hose is nylon lined. Rubber hose as Wendy found out may look the same on the outside, but it is whats on the inside that counts. Randy is right that the Goodyear hose offers some chemical resistance and I use it in the roofing industry when I need 1.5", 2", and 3" siphon hoses.

Cormac, thanks for the info., between our suppliers for parts and this message board I can find out some of the real reasons for the issues we have to deal with in this industry. Off the beaten track; you mentioned that you are involved in the roofing business. I've been thinking about getting into the application of the protective roof coatings. A paint like material that protects flat roofs, as much as 10 years. We are in and out of industrial parks all the time, the buildings are large and hundreds of them with flat roofs. It can't be much different than coating a parking lot? Is this the type of roofing you do?

Hank, are you considering just the application of a top coat? That is fairly easy, especially if it is an acrylic or elastomeric . A top coat is just for reflectance (white or aluminum) and really is not the waterproofing aspect of the roof . A white roof takes on a lot less heat than a black one. Spraying roof coatings can be similar in appearance to sealcoat application in terms of pole guns, ball valves, overlap, and wide patterns. Pumps are completely different as some coatings require 15 GPM at 1000 PSI while other coatings require 3 GPM at 6000 PSI. 300 to 500 feet of hose is the norm. The real expertise in roofing lies underneath the top coat
