Cinder Block

Joewho

I'm looking at an ext. cinderblock wall. Very dry conditions, no scale, moisture or any other problems. It's naked wall, what would you guys do to seal and paint it. This is not a high dollar job and chances are the top coat will be paint, not block filler.

Does paint go over filler? Can filler be used as a primer/base coat?

Local supplier suggest using a solid color stain (Cabot) as a primer then paint as usual, spray on and backroll/brush

SW loxon is what I use...haven't seen to many others that can hang

you can just use it as a primer and then topcoat with anything if you choose

On smooth CMU use sprayed/backrolled blockfiller, then 1 or 2 coats acrylic topcoats. On fluted or cut-faced CMU use solid hide concrete stain with a exylene base. I applied H&C to fluted CMU about 10 years ago to a parts store that lasted 6-7 years with out showing the grey of the CMU.

Brushslingers

Agree.

Thanks for the replies guys. I have a better idea now. Let's see what the owner wants to do.

They want loxon and a discount on labor.

GPI

I am wondering why nobody asked how old or new the block was?

Block and mortar has a certain Ph and alkalinity. Different products for different situations and age of block.

We're in the desert GPI. Where you might see fences in Ohio, is all cinderblock walls here. Streets, backyards, everything. The block is in excellent condition, I'm guessing 10 yrs old. No decay, cracks or any mortor loss at all.
Very clean, no prep except washing and the HO did that today. Small job.

Ive always just used a good quality masonry paint and the biggest brush I could find.Slop it on and rebrush to stop the runs.I even dab it to get into the holes.The first coat I thin with bit of water.Too thick and it won't run into the voids.You want it sloppy.I even wet the wall first,especially on a hot desert day.

Richard

well the paint is good, what's up with the labor thing?

I always give an estimate to homeowners based on what the right steps to take are when painting a project and give them the option of removing the quality. Also, it is a good idea to have some sort of form if you get the job due to them cutting corners specifying they chose to not take the proper steps and that you will not offer a warranty on the project that way you have documentation and ofcoarse with their signiture. If they do not sign you do not do the job!!!

If it's block that's never been painted, prime it with a latex block filler, that is why they make it.

Block filler is way less expensive and fills much better than a finish coat. Then use the finish coat of choice.

Loxon- can't beat it. Goes on anything and everything. We did 40,000 sq feet of a brown with one coat on new block. Looks great. We went over new metal doors and frames and have zero complaints

I figured as much, just wanted to check.

The Customer ownes some income properties. He is very involved and the work is not going to go the way I want it to. I have to stand firm just to make sure they don't mess up their own job.

Wouldn't do this work, but i'm starvin, they know it, so you can guess the rest.
