Topic tags/keywords: spray latex finishing paint hvlp thinning spray gun question

Hi, just getting into spraying and my first little project is a bathroom vanity. I had a little time on my hands so instead of brushing the latex paint finish I figured I would spray it just for more spraying practice.

Here is my question: I use Benjamin Moore paint which is expensive and thicker then most latexes. So in order to spray I have to thin the paint by 30%. So I’m thinking that the expensive paint I’m buying is becoming a lesser quality of paint due to the thinning process, should I just buy a cheaper Paint that is not as thick? It would save me some money.

Just thought I would ask for your advice.

Let me know.

Thanks
Joe

If ypu want to stick with benjamin moore then go with there advance line (it’s not latex by the way), and don’t thin much more than 10%. If that is already what you tried and your spray system isn’t up to spraying it at that viscosity and you don’t want to upgrade spray systems there are other coating options, but cheap latex isn’t one of them.

Solvent based coatings can be thinned much more than waterborne, but come with a voc penalty as well as needing to be done in a spray booth or outside.

I read somewhere that diluting more than 20% you irreversablychange the chemical property of the paint. In my experience even staying in the allowed 20% the latex paint looses its shine and becomes too dull.

Jar944 is right on there money.

Last year I sprayed my new kitchen cabinets. I used Sherwin Williams Arylic Alkyd (similar to BM Advance). It’s thinner than most latex I’ve used, so I didn’t have to thin it very much.

The cabinets look fantastic.

Never tried it myself but you might want to look into using Floetrol. I think it is suppose to help make spraying latex work better without actually thinning the paint. You might also want to pose this question to the guys at Benjamin Moore to see what they recommend.

If you’re having to thin thirty percent, you need to upgrade your sprayer. I see four stage true HVLP systems pop up on craigslist from time to time for a good price (around $400.00).

I have a CapSprayer 4 stage and it’s proven itself worth its weight over and again.

I have an old Titan 440 airless sprayer. It takes about a 1/4 gallon to load up and then a lot to clean. I don’t think it is worth it for a small job. I use it for spraying jobs of at least 5 gallons. I have been contemplating a small short hose and a fine finish tip. I just don’t know if it will work or not for small jobs.

plus thinning can lighten up the shade of the color.

I have not sprayed yet, but brushed some cabinet doors with high quality trim and door paint. Thinned with flo-trol per the specs on the bottle. Got a great finish that doesn’t look brushed. I would totally recommend using it for thinning latex paints over simply adding water.

What are you guys using to spray your latex and acrylic based paints? I have used an airless sprayer for a long time but I hate it for a variety of reasons. Mainly because the amount of materials it waist and the difficulty in clean up.

With that being said, I would love to have a 4 or 5 stage turbine system, but can’t afford $1,000 or more for a quality unit. There is a Greco HVLP 9.0 available locally for $500 but I am hesitant to buy it used due to not knowing its longitivity and Parts availability.

My air compressor is a 21 gallon 1.8HP and isn’t up to snuff for a cup gun or paint pot. This is why I am looking into a QualSpray LVLP gun. Just haven’t been fully convinced this is the right way to go.

I think you can spend a serious amount of money on a spraying set up, but I don’t think the quality increases linearly with the cost. For example, for my cabinet project I mentioned above, I used a Wagner Control Spray Max. It gets a lot of negative comments just based on the name, but it has exceeded my expectations. It’s around $100.

I’ve sprayed water-based stain and finish and it looks great. I sprayed the cabinets with acrylic alkyd paint and they look great.

I do believe I could get even better results by investing in a more expensive system like the Earlex 5500 or a Fuji system, and maybe I will someday, but this meets my needs right now.

Here are a couple pics of my cabinets:

I definitely would never use a cheap paint.

You don’t say what, if any, spraying equipment you have, but The drawback to spraying latex as you know you have either invest in a turbine sprayer designed for it BUT, it is possible to spray latex paint through a gravity fed HVLP sprayer, you just have to thin it a lot. I’ve seen windshield wiper fluid used as the thinner instead of water.

FWIW, I am by far no expert at spraying, but I just finished a project using SW oil based Pro Classic satin & I REALLY like it. The finished coat is exceptional.

Unless you have an aversion oil based paint (or your state has banned them), I think its something to consider. Plus, the sprayer set up is super inexpensive. With just a little thinning, I used a $9 HF sprayer and it worked just fine.

Downside is you need a respirator, exhaust fan, clean up involves min spirits, longer drying time, which may be too involved for you, but to me, it was worth it.

I use an Earlex 6900 HVLP sprayer for all my needs. I spray latex paint just fine with it and an old friend gave me a tip that has worked well. I use winter windshield washer fluid to thin the latex paint about 10%, it makes it flow and lay down very well and is very cheap. The color of the fluid doesn’t seem to effect the paint color in any way, I usually use the blue colored stuff from Wamart and I have had excellent results using this method.
