It would be good to get information about negative side waterproofing e.g. DryLok, Xypex, Penetron (plus the various other solutions to block and mitigate moisture).
Painted our cylinder block foundation (former house) 25+ years ago. No issues at all. Did it to our current house and still don't note any issues. I don't agree with having a hard rule against paint. There are always exceptions. Also, the "pros", at the paint store say don't use paint with a sheen. We did and it looks fantastic, and holds up to the elements- snow, rain, weed wacking (not an element ;-)). Love "This Old House"!!!!
Great video. Could you make a whitewash with white portland, but with some mortar dye added to make a colored whitewash? Or would they dye run out in the weather?
I have a question. Ok so I'm hearing that you shouldn't paint brick because it won't breathe. But what about this sealant, does that stop it from breathing / trap in moisture? Thanks!
Nah it’s definitely a contradiction. I wouldn’t seal or paint any masonry besides underground and you typically tar seal that. I always felt like if you just seal any typical brick wall, if moisture were to ever get behind the brickwork it creates a barrier preventing any of it to ever escape from the front of the wall which is where brickwork is going to dry out from the sun, air and wind, etc.
We have a very old church building and have some moisture issue. We have decided to uncover the bricks to allow them to breath. Could we apply a product that allow us to see the bricks and allows the bricks to breath. They are re very porous and ten to crumble.
Should I seal the inside stones/bricks in a crawlspace/basement? Particularly if they are underground and I have no good way to get to and seal the outside part of those bricks?
It depends. They make a Siloxane based formula which will chemically react with the brick and remains breathable. Stay away from the latex/acrylic ones IMO they don't breath and are not advertised to breath like the siloxane version.
How about undoing the damage the previous home owner did? painted the field stone basement. Yes, it leaks when it rain. and how about removing the paint on the bricks (on top of the fieldstone) as the are 125 years old and I think they need to be repointed. (I would ask someone first about that)
@PTOWN6000 No, I have not. Would truly appreciate the guidance. Would like to keep and seal brick as it is. However, if paint has the same effect, then that will open options to new and different update. Appreciate your thiughts.
You didn't even discuss the products! Shame on you. What is the stain that goes on concrete block? Water based? Solvent? You can't stain it after the sealant. You never mentioned this. Disappointing video.
Oh wow!! Let’s all throw you a parade. Before we do, why don’t you tell all your friends and family this exciting news?!! Oh wait, how excited are you to get your trophy and plaque? I think they will ship it to you soon. Go ahead, tell us all how excited you are!
Do you win anything for being first? Does This Old House send you a plane ticket so you can fly out to meet them? Or do you get to have your own dilapidated property featured on the show so they can fix it up for you?
Lime washed my 2000 SF house 3 yrs ago. A couple bags of plasterer's lime for less than $40. Great look. Couldn't be happier with results.
You did it yourself by hand in SF?

Just had MJM Masonry rebuild and seal my chimney and couldn't be happier
I just repair my cinder block chimney… I’m thinking of doing this
Any chance you can have Mark make a video about parging (masonry coating) a CMU block wall?

Did you use primer or just threw paint right on? Doing my own job
I’m so happy this video exist thank you
Surprised no mention of mineral silicate coatings. Oldest coating for brick and masonry in the world and still used today. Vapor permeable coating
Just say Lime Wash. It also repels bugs
@@loloholmes2793 Lime wash also works, but that's a different product than the one i am discussing.
@@JDCrae and this is why i read the comments. thanks im gonna look this up
Great information 👍

1:23 I think the black tape is covering the brand "BEHR"
So am I hearing correctly that Mark recommends NOT sealing a brick walkway, porch, deck etc?
When they say seal, do they mean waterproof, or just sealing the look?
I believe it means moisture barrier
I have a question. Ok so I'm hearing that you shouldn't paint brick because it won't breathe. But what about this sealant, does that stop it from breathing / trap in moisture? Thanks!
He literally said in the video that it does not
@@MandoFettOG I'll watch it again, but I didn't hear him say those words or clarify the difference.

@davidalearmonth did you ever get a good answer to this? I like the look of just a sealer on my brick, but don't want to risk sealing it up too much.
@@Church-X No, I don't think I ever heard back.

I want to remove old thick chipping paint from brick what materials or tools should I use to leave the brick to its natural state.?
So if I stain my outside cinder blocks should I seal it afterwards
Good idea. Trap the moisture inside the building.
So the sealer (on an older house) goes on BEFORE the stain( if you’re changing the color) ? THX for this video and info!
So should I exactly sealer cinder blocks before staining?
Thoughts on staining a red brick patio to change the color? I really do not like the red brick look
I'm about to buy a painted brick house. Should i attempt to strip it or just leave it?
Don't buy the house lol have it sand blasted painted brick looks like 💩 after awhile flakes and peels
Won't chip or peel if you use good paint
guess depends how the paint looks
Is it painted or stained?
Does this sealer leave a smooth finish on brick?
Does the color top stain need a primer on concrete block?
Does Drylock prevent brick and concrete from breathing?
It depends. They make a Siloxane based formula which will chemically react with the brick and remains breathable. Stay away from the latex/acrylic ones IMO they don't breath and are not advertised to breath like the siloxane version.
What if you already painted your bricks can you remove the paint to put the sealer
Lol

Allegedly there are companies with laser cleaners that can remove paint by burning it off without damaging the base material.
what is the product?
Would the sealer not have the same effect as paint? Sealing prevents the brick and mortar breathing.... no?
Did you get an answer to this somewhere? I like the look of just adding a sealant.
@PTOWN6000 No, I have not. Would truly appreciate the guidance. Would like to keep and seal brick as it is. However, if paint has the same effect, then that will open options to new and different update. Appreciate your thiughts.
Paint traps moister behind it. And the sealant repels the moisture
I want to stain brick ... Do I use concrete stain ?
Wouldn't stone suck-in foundation sealer become slippery and crumble? Did Inca Masons use sealers on their stone foundations??
A whole lotta of wood ash.
Masonry paint supposedly allows brick to breathe unlike latex or oil.
sure clean 600 is acid.. I have used it for years
👍🤙🤘
Paint the outside brick? That’ll look hideous! He neeyto talk more about the clear one
He who cannot be flapped

I for one am genuinely happy for you Steven. :)

@@johnlebzelter4208 the fact that you’re that raging over a 9 year old enjoying a show and being happy says a lot about you 😂😂
Very environmentally friendly...
Danger poison, LOL. :)
You can add a additive to sealer for a non-slip on flat surfaces!! Rhino 🦏 grip is just one of those
