Please Advise Me on Exterior Paint That'll Survive the NM Sun

Ματθιας · Aug 31, 2020

With the summer winding down, I'll looking to paint a shed before it gets too cold. Before I start dropping money on paint, I thought I'd ask what you all think would be best for my particular application.

It's a Tuff Shed - so it's not really wood, but some sort of "wood-like" material - it's like pressed paper if I were to describe it -. Fiberboard? It's about 20 years old.

I don't know anything about paint. I'm wondering what kind and brand would stand up the best? Would it be an all in one paint and primer? Primer, then paint? The biggest issue is going to be the almost constant year round Sun and low humidity.

I'm going to be painting it an almost a paper bag color brown with a lighter tan - Khaki color for the trim if that make a difference.

Any advice would be be greatly appreciated, thanks!

Take some up close cell phone photos and go to your local Sherwin Williams or other paint store and ask what they recommend.

I've used whatever cheapo latex. Call the local hardware store or talk to your neighbors or the guys at work.

Friend of mine is a painter. Owns his own company. He only uses Sherwin Williams.

Similar climate here. My shed is painted with Sherwin Williams most expensive outdoor latex. I forget the name, but it was their top of the line. It is holding up well after about 12 years of our bright sunlight and mostly clear skies.

Do not buy cheap paint. You will regret it.

Sherwin Williams is some of the best. You don't need their top of the line most likely.

If the paint that is on there now is good, paint right over it. If you have other issues like lots of bare spots, then prime.

45 years in the paint business, Sherwin Williams is a ripoff. They make their money off of retail sales. Contractors can buy the same products from them often at half the price. Find a paint manufacturer near where you live cause that's where they test their products. Avoid paint and primer type paint, it's had a corner cut in it somehow. Use a top quality 100% acrylic primer where needed and a 100% acrylic finish coat unless a rep from the manufacturer you deal with tells you otherwise.

The last time I had my house painted they used Dunn Edwards paint. Best paint I've ever had on a house. Its been 7 or 8 years that it was painted and it still looks great.

I had Sherwin Williams Duration used on my home many years ago over an oil based primer. I am not in NM but it has held up very well. At least 10 years old with no sign of cracking, peeling or fading. Duration(R) Exterior Acrylic Coating - Sherwin-Williams

Oil based paints seem to last longer and are more durable.

Ye, contractors buy their paint at a discount from Sherwin Williams. That should come as no surprise to anyone. Check their ads for sales, ask their advice and take it. Don't be afraid to ask the store manager for a discount if you are buying more than a few gallons of paint. We use their paints exclusively on homes we remodel. Dont' buy cheap, it's expensive in the long run.

You're welcome. If it works on truck beds why not for a shed???

I am a fan of Benjamin Moore Paint its expensive even with a discount...

I have used Sherwin Williams and it is a good paint also. We used to paint our shop floors with polyurethane porch paint was good stuff in the day.

Paint formulas keep changing to meet newer regulations. What was a good product is no longer made now...

For the OP, surface prep is EVERYTHING! The surface must be clean and not chalky. The surface must have some grip for the paint to adhere to, sanded?

Next is if the material can transfer moisture to the surface. This can cause adhesion issues and blister or peel the paint.

Id ask at a paint store, if possible bring a sample of the material. Id also ask about proper surface preparation, pressure wash, sand, prime? Perhaps, etch, sealer, prime?

Good luck with your project. Time spent in figuring it out now will make the job so much better in the end.

Maybe in the 1950s when they used lead pigments and mercury as the mildewcide but not today. Oil based paints are far more brittle, don't expand and contract like waterborne. Paint manufacturers are putting all of their research in latex products. The only reason one uses oil anymore would be over an existing oil finish, on ferrous metal or where an extremely smooth, glossy finish is desired like a door or trim.

The yearly paint debate!

All the major brands are GOOD or even GREAT.
Any of them will probably last longer than the average member on this forum will

Prep is more important
Look up the "best exterior paint" I do not think any of them agree on #1.

Not particularly relative to your situation but ... On Long Island, we had a big old wood framed picture window on our southern exposure. It took a beating and didn't hold paint.
Hubby's friend was a pro painter and told us to use oil-based Benjamin Moore and add a product called Penetrol to it. 22 years later, we sold the house and that painted window still looked like the day we painted it.

Best advice I was ever given was to use an oil based primer on the exterior. Oil based primer prevents the migration of moisture through it therefore a latex topcoat is fine over it. If a latex primer is used the movement of moisture will cause the failure of an oil topcoat and to a lesser degree a latex topcoat.

For the best UV resistance, you can't beat 2 part (polyester urethane) paints. Great stuff, but not "homeowner friendly"

Maybe on old or weathered wood, oil primer penetrates due to the slower drying time, definitely not on new work, 100% acrylic latex primers breathe allowing whatever moisture is left to escape. Put oil primer on wood that hasn't completely cured and the moisture will cause it to pop.

Similar to Imron, spec. sheet shows a limited number of substrates this product works on. Definitely not house paint.
