Mike should I seal my NEW contreteo concreate bathroom sink before I install it? If I seal it I want a matt finish. What is the best sealer to use?

[@TheFinalOutpost]

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

[@joeyting341]

Hello Mike, I have 2 questions.. 1.) During the colder weather around 30 degrees what concrete sealer can withstand the cold. 2.) I poured the concrete around in the 40-50 degrees but I wet the garage floor concrete to cure it a little too much now there are black spots. What measures can I take to resolve this. Thank you Mike.

What sealer should I put in my basement, I plan to lay under layment and install vinyl flooring after. Thanks in Advance!

[@TheStigma]

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.

[@PebbleBeachCorolla]

Besides foundation armor, what are 2 good choices for water based penetrating sealers. Do any of them rate the % solids in a gallon?

[@robertalvarez7059]

Will the bubbling occur right away after sealing?

[@dangerkin1]

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.

[@graysonquenelle]

If you power wash the patio, then roll on the decorative sealer is that good enough?

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]

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

Hi I’ve just had a new patio laid and to save money I’ve sealed my own and from comments I’ve had from people I’ve got moisture under it as it’s dried white milky consistency is there anything you can recommend to remove it please I’m devastated? X

[@MikeDayConcrete]

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.

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]

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.

[@johndoddato2662]

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

HOW OFTEN DO YOU SEAL CONCRETE?

[@SteveP-vm1uc]

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.

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.

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”.
