I am using an angle grinder to sand down my trailer. I am using a 40M pad. (i have no idea what that means) but it's working. Is this what you guys do? I have never sanded a trailer, especially with an angle grinder. Just want to make sure I do it correctly. What are the do's and don'ts?

Do you have access to a sand blaster, or a place where you could rent one?

I guess I could rent one but that's just more money that I have to spend. What are the advantages? Does it do a better job or is it just faster?

from my experiences, its just easier. You can get in all the little spots. Its like painting with a spray can, instead of a brush.

I have repainted and touched up my trailers several times.
I would just clean & lightly sand all the angle iron, square or round tubes, and any other larger surface areas. You really cannot sand effectively any of the expanded metal surfaces without a sand blaster but that ok, just clean the surfaces of dirt and grime(maybe a power washer but not necessary). Then I would use semi-gloss enamel spray paint cans or borrow a sprayer and have at it. Ideally you would want to sandblast that trailer for a perfect prep job before painting, but this is not a porsche with a perfect paint job and clear coat. I have done this several times and the results are very good.

Also, I assume you are taking about an open trailer.

Yes it is an open trailer. I was just at my local trailer dealer buying some parts for my trailer brakes. He said that an angle grinder with a 40 or 80 pad would be fine to sand with. I just need to prime it asap, seeing how it's exposing bare metal right now. For the hard to reach areas I will just hand sand I guess. Thanks for the responses, you've been very helpful

Here are some work-in-progess pictures. Just got done sanding. Getting ready to prime it.

Primed and ready to paint (the front half)
I didn't wash the trailer before priming it because I didn't want to introduce any water to the exposed metal. Is it ok to lightly power wash it now that it's primed? I'd like to have it as clean as possible before painting, which may not take place for a day or two and it's sitting outside.

thats sweet bro. Im painting the black one tommorrow. I powerwashed mine with my extremly high pressure bit. Its an 11hp engine on that sucker, and that with the high pressure bit took the paint right off. So tommarow im going to prime it twice and put like 3 coats of black paint on it. Then ill do the bearings because if yours needs em, most likely mine does too.

Just curious, how long did it take you to sand/grind yoiur trailer completely? How many hours?

Expert Lawns
03-27-2005, 11:48 AM
mark and troy......get a room (or forum). Mark is right, the snow down here is gone. sun has been out for 3 days and its been in the upper 40s lower 50s. Very nice weather to knock the cobwebs off the equipment.

burnandreturn, it took me about 2 hours to sand the entire trailer. This, however, does not include the tailgate. I am waiting to get some spot welding done, then I will sand and paint it. I will be putting 3 coats of high gloss fire engine red on it. Then stripe it with some reflective tape

and it only took about 1/2 hour to prime it

What has worked for me is wet sand blast the trailer. I pay a guy $100 and he does it all plus pressure wash the wood floor. I take all the light off and he does it. Then spray it with a prep coat, then primer twice then use commercial truck coating for semi - trucks. It doesn't chip or scratch that easy. about every 3 years I would re do the trailer. Also you should re pack the wheel bearings every 10 to 12 thousand miles. You can also buy special bearings that have a bulls eye and it forces any grease back into the bearing as you drive they are pretty neat.

I would get a ''tack rag'' and go over it with that and not have any moisture on the trailer before I painted it

I would not power wash the primer. What brand and type of primer did you use? Check the label on the primer. Many times there is a window of time to recoat. If you wait too long you must sand the primer or there will be a loss of adhesion of your top coat, it will flake off quite easily. Due to the nature of your business you need the best paint job you can get if you want the finish to stand up to the constant washing and abuse equipment trailers go through. I have attached a couple of photo's of the type of equipment we refinish. All oilfield equipment.

If the primer is fully cured I do not think a lite power washing would hurt but be sure to dry it off- towels & the backpack blower would work. In a couple days when your ready to paint it, go over it to remove dust that has settled on it with tack cloth, towels, etc. If possible, I would wait for a warm day to paint. Also, any airborne particles will settle on the paint if you do so outside. (small bits of dust and such)

What is the safest way to clean your brushes? Simple question, but I HATE doing it, just wondering if you guys had any better methods. Thanks

I just got back from painting mine. I primed it twice and put 3 coats of high gloss black on it. It made a world of difference. now tommorrow when im working, I wont look like a sleeze ball :cool2: payup

Hey Mark, did your first coat look like crap? I just did my first coat and I can see a lot of brush marks. Also, the red paint and brown primer is making the trailer look a nasty brownish orange. Hopefully this will go away after the 2nd or 3rd coat

Here's another update. You can see what I've sanded, primed and painted and what hasn't been touched yet. I've finished the outside. Now I have to powerwash the inside rails and paint them, then power wash the floor and treat it. Tailgate will be last since it still needs some welding done.

This is 2 coats of primer and 2 coats of fire engine red

I kinda wish I sprayed it. Thats how I painted my other trailers and they had a better finish. I'm not about to sand this down and start over. Maybe next year

I always like to brush the paint on, seemed to get a thicker coat of paint on it , the thing I didnt like about spraying a trailer was it looked better, but the paint was usually thin and would get knocked off easier

thats reassuring since i'm putting 3 coats on it. this trailer better be indestructable

Hey Expert, how long have you had this trailer? Did you buy it new and had to repaint it two or three years later? Just wondering how long it takes for a trailer to look like that being all rusted and all. Mine is new last year and I went around it before I put it away for the winter and touch up the dents and scratches. Up here in the northeast we to get alot of snow and rust :angry: O'well . It looks great what you have done so far. Thanks for putting up the picks and keeping us up dated on the looks of the trailer. :D

Hey Expert I forgot to ask ya if you had a "plate" for that trailer jack? If it's just that pole I would think it would go down deep on hot payment and or grass! Just my two cents. Again looks like great work in progress.

NH Boy, I bought it used about a month ago and have yet to use it. My last trailer lasted 4 years and I saw almost no rust at all. That trailer never saw the snow and salt, I kept it stored inside. That makes a huge difference. The trailer jack you commented on is only the pole, I haven't bought the wheel for it yet. The ground isn't even close to getting hot enough for it to penetrate through, but believe me, I have seen it happen and thank god I know better. Thanks for the compliments on my trailer. All I need now is some different tires and she'll be ready for summer.

Mark, did you treat the floor with anything? I don't remember it being that color or in that good of shape, but maybe I didn't pay close enough attention.

Hey premier, when you said you primed it twice and sprayed three times did you use "spray paint" or an air compressor paint? Just wondering for my own trailer.

Mark, what are the chains for on the rear gate? Looks like something to do with the pins to hold it up. As you know, I need a few of those for mine. Just wondering what works best. Trailer looks great by the way

RedWingsDet
04-01-2005, 11:42 PM
chains are so if I drop the pins, I dont have to worry about loosing them. The chain is attached to the pin and the angle iron. And thanks for the compliment. It only took 1-2 hours to prep and paint.
