Hi everyone! Ingrid has asked me to post the following questions for her. I'm not sure on all the details, but this is the message she left me... They would like to paint on a old concrete wall that has been sandblasted. They are going to prime with an alkyd resistant primer. She is wondering if they should use acrylic latex or lettering enamal. Your response is appreciated....I will pass on the info to her. Thanks!

Both acrylic latex and alkyd enamel will work just fine! It all depends on what she finds easiest to use. Personally, I preffer lettering enamel, simply because it covers better.

I would strongly suggest that they prime with a good acrylic and then paint the wall with the same brand good quality acrylic. Acrylic paint sticks to concrete very well and also has the ability to breathe- something that enamels don't. THis is important on concrete.

I agree with Dan. While latex doesn't quite cover as well, it dries fast enough to recoat several times over the same day. Also, I've never had a failure with latex on concrete walls. With oil base paints, I've had several failures even though I did everything right.
I was talking to Gary Anderson at the Letterhead meet in Evansville, Indiana this past weekend.
I asked him why my acrylic latex job failed after 5 years when everyone else seems to get 10 to 12 years out of it.
Gary asked me how many coats I put on. I said 1 coat. He said, that's why. Try 2 or 3 coats next time. I said....well duh! How could I over look something so obvious as that? -------
Now the other side of the coin.
Pat King was also at the meet. Pat pretty much has no use for acrylic latex. So I asked him how do you get your oil base paint to last so long?
Pat said, "Its what you put in the paint that makes it last longer"....Try adding Spar Varnish and then only thin with turpentine, never use mineral spirits. That's his trick.
So there you have it. Two ways that will work, both different, both can achieve long lasting results.
There is probably less learning curve with acrylic latex. But be sure you use 100% acrylic protection latex, not the cheap stuff.
Benjamine Moore, or Porter or similar brand.
