There's a question about what kind of sealer to use on stamped concrete.
There's questions about penetrating concrete sealers.
There's a question asking if you can tint or color a concrete sealer. And another question about what's the best concrete sealer to use on an exposed aggregate concrete driveway.
There's also a question about why does a concrete sealer blister.

Followed your advice using Foundation armor. Resealed my decorative concrete patio this year using AR500 and it looks great. Thanks for the help Mike .

@larsonhomeinspection9932 3 года назад

Hi Mike, great videos. I would love if you did a video on concrete curing. Water curing, sealers, etc. I think it's so critical but rarely done properly.

@TheFinalOutpost 3 года назад

Hey Mike, I have a question: I recently had a stamped concrete patio done back in July; I've noticed that in some of the areas with higher foot traffic, that the sealer//wet look is wearing down already. Does friction typically wear down acrylic, solvent based sealers this quickly? Thanks

@transmitterguy478 5 лет назад

Interesting stuff!

@dangerkin1 4 года назад

Mike I power wash typical concrete driveways and patios all the time that get some mold. We are thinking of now also offering to seal them for people. Do you recommend the Foundation Armor 5000 or the Radon seal? Or is penetrating seal the way to go here? I guess your best all around seal recommendation for driveways and patios. Some patios are stamped. Thanks for all the videos.

@tinadogmom8586 4 года назад

Hello Mike, when I originally bought my house 3 years ago it had a great seal that was non slip and keeps concrete cool to touch, it appears slight wet look and does have stain...do you know what the best product to get this back is? I'd say my dec is probably over 1000 sq ft?. Thank you for your videos :)

Hi Mike, We poured a patio last fall and sealed it with a good solvent based sealer. Just in the past week we are seeing small brownish red spots. I tried scrubbing them with dawn and rinsing but it did not touch them. I then tried a household cleaner and bleach and then hitting them with a power washer but still nothing. I am starting to think they are below the sealer as I can still see the sheen of the sealer when it is dry. What do you think Thanks

@DrLem 2 года назад

Mike! Thank you for your videos, so much! Question: can we apply Thompson Water Seal to green concrete to help retain water for curing? Yesterday we poured 1200sqft of 2" "rat slab" in our [soon to be] crawlspace, floor joists are not in yet. A friend gave us 10 gals of TWS and I had thought to spray that on. Google research is all over the place on this being a good idea. Side note, I had your narrative in my head the whole time I was building screeds and pouring 8.75 yds of mud. Thank you!

Question: How does a penetrating sealer (ex. Siloxane) affect adhesion? I'm thinking in relation to floor paint or epoxy for a garrage type situation. Is it a good idea to lessen moisture soak from below, or a bad mistake in terms of getting good adhesion later? This presumes good pre-treatment of course, not just slapping it down.

curious if anyone had places on the floor that the sealant didn't fully absorb into which then turns into a sticky spot/trap for insects. despite endless power-washing before i put down the sealant, some sports were stained bad and these are the spots that i'm now left w/ a sticky mess at.

@jesse4589 2 года назад

Anyone have experience with L&M aquapel? I sealed some of my concrete driveway with this yesterday. The side walk it dried essentially clear. The driveway has a brownish tint. The driveway had 24 hours to dry after pressure washing, the sidewalk had 36. Could that be it? It all came from the same 5 gallon bucket of sealer and same sprayer. My first thought was I didn’t clean the broom I used for the puddles out well enough. But I used the same push broom on both surfaces. The concrete just looks “dirty”. I might try to lightly pressure wash it in a week or so and hope for the best.

@annettecompton9088 2 года назад

Hi Mike, thanks for putting out this content. I put a solvent based clear acrylic sealer on our recently poured porch (45 days ago). There are roller marks from the first coat and we are going to need a 2nd coat. Is there a way to get rid of those roller marks on the 2nd coat?

@dustyniederriter7543 2 года назад

Do not add another layer until the roller marks are dealt with. By adding another layer will only make it harder. My experience is that Xylenol is the way to go dump some out and work it in with a roller to activate the sealer that left the marks. When done I would acid wash, neutralize, dry and spray sealer during the cool Time of day. Never in hot sun. I’m guessing the roller marks happened due to being sealed in the hot sun and or on a windy. It was drying faster than whom ever was running the roller. For best results use a sprayer. Chances are you will be still Left with a sub par job. The best finish in the world can look like dirt if the sealer is not applied correctly. Good luck my friend.

@leonardcunje7540 4 года назад

The sealer isn't really going to smooth out the pavers. You can apply the sealant anytime after the pavers go down as long as it's all dry.

@beeisbad 3 года назад

Hi Mike... QUESTION: If I put a high solvent high gloss concrete sealer in my basement... are the high VOC (carcinogen and other toxic materials) fumes STILL considered to be dangerous AFTER the floor dries? Or is it ONLY dangerous while applying and not dry yet? And if the answer is "Yes" these type of VOC sealers are still dangerous for indoor purposes even AFTER the floor dries... do you know of any "High-Gloss" water-based sealers that you would recommend for indoors/basements? Thanks again!

@MikeDayConcrete 3 года назад

The solvent sealer will not be dangerous after it dries, but the fumes will linger for days and it's fumes are flammable so we don't recommend in a basement. Here's the water based one you can use that's high gloss: amzn.to/2YJtsjb

@johndoddato2662 4 года назад

Mike, I have a garage floor that is 12 years old. The concrete was power troweled and is very smooth. I want to clean and seal the floor with a clear sealer. My problem is the previous owner had oil leaks on the floor. The floor also has hot tire marks. I have tried to clean off these stains and nothing works. There may have been a sealer applied at some point on the concrete because I can see some areas that appear shinny. I tried some denatured alcohol to see if it might be a water base sealer and it did not change the area I applied it on. Will muriatic acid clean up the concrete enough for sealing. I know I won't get it looking like new but would like to get the floor sealed and prevent anymore stains. What is your thoughts on prepping the floor and the type of sealer I should use? I have thought about grinding but really don't want to go to that much work to just clean and seal the concrete. Thanks, John

@MikeDayConcrete 4 года назад

I try applying some Xylene solvent to the sealer. Pour a little on a small area first to see what it does. It'll re-emulsify the sealer and should let the moisture escape. You either got the sealer on too thick or sealed over some damp concrete. If the xylene seems to work, just spray some on the entire area, may need to do it twice. You could even spray some on the sealer and back roll lightly with a 9" roller to spread it and work it around. It usually takes care of the whiting of the sealer.

@SteveP-vm1uc 4 года назад

I have a question that I don't think was covered. (No pun intended). I live in the Tampa Bay area and my driveways are 31 years old. I don't think they have ever been sealed. At least not in the ten years I've been here. Our North driveway runs against the neighbors grass and he waters a few times per week. Much of the water ends up covering a large stretch of our driveway and that entire area is full of mold. I have pressure washed it each year and it really doesn't take long for it to come back. Monday I have a pro coming to pressure wash all the flat surfaces. Both driveways and all of our sidewalks. (Corner lot with a wrap around back drive to the shop and out to the side street). I'd like to seal the driveway after he does his work. If this was your property, how would you handle sealing the driveways to best keep the mold at bay? Remember, the neighbor water it about 2 times per week!! I have about 3000SF of concrete driveway total.

@MikeDayConcrete 4 года назад

I would use RadonSeal deep penetrating concrete sealer: www.radonseal.com/radonseal-mitigation.htm If it gets wet a lot and is in the shade, it may still develop some mold, but it will wash off much easier.
