Definitely the correct process for the job shown here. I once painted a 2’ high cinder block interior garage wall. The garage was being done nicely for the homeowners new corvette (epoxy flooring, custom tool cabinets, LED lighting, etc. ). Because it was a relatively small area unaffected by rain or sun I used spray paint on all the mortar and then rolled the wall using a high nap roller. 2 coats and done.
So cinder block (CMU) is what we call a "paint eater"... the porous and rough nature of the substrate makes using a bonding primer unnecessary (practically speaking). Type latex paint can cover at 300-400 s.f. per gallon. But this is at 1.5 mils thick (dry) and it takes two coats AND this is for non-porous substrates... I would plan on 1 gallon per 70 s.f. We spray and back roll the first coat then apply a generous second coat. Applying thicker coats (more than the manufacturer recommends) is generally not a good idea... but with cinder block it just drinks up the paint and really doesn't have any consequences to applying heavier than normal. Let me know if this helps or if you have any further quesitons.
Big Noob Amateur here. I have a cinder block older home that has been painted..... What options do I have if I want to prep for paint or even amateur stucco application ? Thanks
If it already painted then a good pressure wash with a good day to dry (if winter, make it two). You can then paint directly from there. If you have "problem areas" a good bonding primer will help. Be advised... WATER IS THE ENEMY. Fences are notorious for having future failures due to the opposite side, top, or bottom soaking up water and destroying the CMU from the inside out. If you want to stucco contacting a good stucco guy is your best bet. But also be advised... The stucco WILL CRACK and you will need regular maintenance. Stucco is rigid and fences can move. You'll see this especially near the areas between panels. Hope this helped.
Can you list the equipment that was used from the sprayer to the air tank that was used to complete the job ? because I have a project that I’m working on in my restaurant with my wife , and I want to spray paint cinder block wall and follow it up with a back Roll just as you guys have done
@@rolandorod7811 Most of our projects (exterior home repaints) use a 517 to 619 tip size. We don't purchase larger tips for these projects but you could go higher.
Great question... The customer on this job did not want to pay the extra cost if it would make the cinderblock completely smooth. Block filler is good... but it's not that good! Thanks for the question and the feedback.
You said only the inside of the blocks are going to be painted but not sealed concrete blocks take on water so if you paint one side and not seal both sides and paint both sides aren't efflorescence going to be a problem making paint peel and bubble. Im watching this and dealing with this problem as i watch your video. I think when water hits the concrete it has a chemical reaction thus pushing the salts through the paint causing a flaky bubble appearance .
Yes. This is a problem. The issue is the most typically the "other side" of the fence is not my owned by our customer. It's owned by their neighbor. And the neighbor can do whatever they want. They could, if they were spiteful, hook up a sprinkler to soak the wall day and night... This is the difficulty with these types of barriers. Does that make sense?
so I have this exact wall ( Rancho Mirage, CA) I am planning to paint. our neighbors have a hedge on their side which does get watering everyday. We have drilled paths the mortar on the bottom cinderblocks to allow of water to 'escape', but still water comes through a little on the first block or 2. Is there an additional primer, or step I can take before painting our side that will help with possible future peeling/bubbling? @@mikericker3434
This is q question that could fill a book... cinderblock does does not have the issues other substrates have so traditional priming is normally not required. As far as Block Fill.... Sure... it's a great idea. For us it comes down to the budget of the customer.
Sorry I repeated the question. I forgot I commented before. I have painted a lot of block and never Not used blockfiller. I do understand your reply,thanks.
The only time we have EVER seen this is if you have a "view fence" in your back yard. This is the square tub steel fence normally on the back part of the fence if you live up against a golf course or some type of open desert. Due to this, other looking "in" could see the color of your fence and it may be regulated. Hope this helps.
@@mikerickeraz Thank you for the reply. My wife and I are emailing our HOA just to be sure it’s OK to paint our interior brick wall. If the HOA gives us the OK we will definitely be getting a estimate with your company. And we do not have that steel fence thing you’re describing .Thank you for your time.
