very helpful - thanks. You should be a teacher the way that you explain things step by step and clearly!
thank you
Great post! I’ve been hunting around for an option to seal my homes foundation b 4 applying paint then putting back the sand fill that I had 2 remove to get to the foundation slab and exterior wall. So far the best if about 30 posts on TH-cam.
Thanks!
Great video I have been looking for this type of nformative easy to understand content for a while now much appreciated.
still gobbling up the series man, awesome format / presentation
I need to find something that will keep water in and keep water out. Allowing me to regulate the water levels without the intrusion of ground water. Will either one of these products work?
really enjoying your videos and how informative/educational they are. keep it up!
Thank you
Excellent video !
I was searching for such a information !!
Thxs !!!😊
I was looking at a new house to buy. Basement leaks. I went to a job site where they were pouring new foundations. 😑. No exterior sealant.
What about under the floor and exterior seem between the walls and floor
Can you please suggest the existing walls probably for the basement where the exterior walls are filled with soil, if seepage occurs at that region that is already built ?
Thank you for this. I bought a 1940 home that has a concrete block back wall that is completely bare- and had a couple cracks. How would you recommend sealing the cracks? Thanks again.
Can we do plaster after coating or brushing the water resist coat chemical processes that you did sir
what tinner is best for liquid rubber?
Can I use this inside of my basement on the cinder block wall in the crawlspace?
The gray stuff can be
@@D.I.Y._All-in-One thank you
Thanks a lot man! Exellent info and great skills!!!
How long did you wait from the block wall being constructed? I've heard 28 days is what's needed.
Great video! I need to hire a contractor to get a room addition built but I am not sure if it will be cheaper to get a block or poured foundation. I have been told is more labor intensive and more expensive to get blocks, but then someone else told me the opposite. Not being in the trade I am not sure
hi you mentioned that the thickness of the black product you like to apply is 60 millimetres thick??? that's 6 cm??? do you mean 6 millimetres ? Thanks informative video
a “mil” is 0.001 inches, a thousandth of an inch. so 60 mils is about 1.5mm. for comparison, the plastic sheeting sold in hardware stores is only 6 mils thick
thank you for clarifying @@RegretWhisperer
I've got a 2ft retaining wall in our front yard that will be holding back some dirt, would this be overkill? The other side of the wall may be tiled in the future so I worry that the moisture from the soil on the other side may leach through and ruin the tile after some time. Cheaper solutions.
Can this be used inside a boiler room in a house....? I need to fix beneath the outside brick steps which is above the boiler room. The steps are over the boiler.
Very helpful video thank you
Will this work to seal the inside of my basement?
Can these products be used on exterior brick walls?
Do you have any experience with wood foundations? Or suggestions on where to look for advice with sealing a wood foundation
So the wall doesn’t need to breath. I hear some walls need to get air
How long should we wait for the concrete grout between the blocks to dry before applying the black duck sealant?
This is my exact question ???
I would think fully cured but that’s over 30 days. I see everyone filling back of retaining walls a lot sooner. I’m thinking water proof the back side so I can finish the back and it can still dry through front ? Anyone out there ?
Thank you!!!!
Can I use this product on my garage floors to prevent water penetration on the cracks?
No, a garage floor epoxy would be better for that.
Doesn't it need to breath though?
Nice! Waterproofings are very interesting. There are many different ways to get them done. Just completed mine.
After this video, feel free to take a look.
Thanks for sharing.
I’d there anything like a product I can paint on concrete block to seal it
Where can i buy this?? Im in upstate New York
I want to do this. Excellent video
Is this good for besement floors?
No, this is designed more for the exterior.
@@D.I.Y._All-in-One can it be applied on a basement interior concrete wall which has water infiltration
I saw you mentioned about HENRY brand ..sold at Lowe's
Is it also like Rubber?
If. I put duck coatinng just for the interior and not extior will that cause issues?
Yes. Your blocks will deteriorate.
How thick is one mil?
With just a layer of paint, you will get water leakage after a couple of years. No matter how good the paint is, just the paint alone is not enough, as the wall cracks over time.
I am a licensed building contractor. That wall needs to be parged. Portland cement, lime mortar mix.
Is it too much to add French drains around it as well?
That's what I did
There is no such thing as overkill when it comes to foundation waterproofing. Cheaper to go above and beyond than dig everything back up and start over again.
@@forced_youtube_handle 100% agree!! I over killed mine.
What do you suggest for chipping concrete driveway. I had a patio and driveway poured about 6 years ago and in the process of drying it cracked. And now I'm getting chipping in the driveway. This is in the Midwest. Thanks!
Wait, won't this trap humidity in as well?
The biggest concern is to stop moisture coming in.
2:10 60mil? What's your mil. Hopefully that's not millimetre or you didn't mean sixty?
Typically "mil" is used as a measurement in thickness in thousandths of an inch. 60mil is 0.060 inches.
Oh thanks @@frederf3227
I'm metric schooled.. hence my bias.. 😀
Did you have to parge it first? I’m getting ready to build my 1st house on a basement. Is this an alternative to parging?
Parge, seal, prime and paint.
Spraying gets thicker layer
So the black one is for Walls that don't look as nice?
The black is more for below grade use.
SO is your basement dry?????
Yes, of course
@@D.I.Y._All-in-One Good to hear!
Nice
Never backfill until the floor joists are on
60 Mil? Where I am, that would mean 6 cm. What do you mean? 60 thou, ie 60 thousandths of an inch?
I know it's been a while but a mil is different than a millimeter. One mil is 0.0254 mm
@@matthewbloomfield ok. Over here, we would call that 60 thou (short for "thousandths")
Do you know 60 mil thick is 6 cm thick,
mil does not stand for millimeters.
@@D.I.Y._All-in-One Good morning, what does it mean sir?
Why not a airless gun?
Make?
Sure the wall is dry and has been dry for forty eight hours before doing anything
Have to say, do you honestly mean 60mm thick
Mil is a different measurement than millimeter/mm. Mil thickness is a common measurement in manufacturing. A "mil" is a unit of thickness equal to one thousandth of an inch (. 001 inch). To convert mil to inches, take mil and divide by 1000. Example: 2 mil/1000 = .002 inches.
@@D.I.Y._All-in-One Many thanks, sorry about that, another senior moment for me.
How about spraying the first layer, then brush the next 2?
What is 60 mil thick?? Certainly not 60 mm...
60 mil, thick, and applying to layers that thick that would be really thick over a quarter inch. There’s no way he’s putting that much on with those brushes . Me personally if I was to do this I would prefer to spray it and just spray two layers or three or four.
@@me5768 I found in the meanwhile that by mil they mean 1/1000 of an inch. So one foil would be 0,06" or about 1.5 mm thick. What confused me is, that in Ireland "mil" is a short for millimeter.
Liquid rubber and simple guard are foolproof
What product are you actually using for the demo? It is not the duck coating you referenced in your intro.
Can you do this on the inside lol
Henry makes a white product that is good on the inside, it’s for sale at Lowe’s and you can apply with a paint roller.
60 mils thick? That's over 2" my friend did you mean 6 mil?
mil is a different measurement than millimeter/mm
Cool
You sound EXACTLY like ETA prime.
That's funny. I have a retro gaming channel as well

No footer tile or rock ?
Nice :-)
Nice. T H A N K S
How to Waterproof Your Block Foundation (EASY)
60mm thick? Assume that is supposed to be 6mm thick
60 Mil equals 1.5 mm
@@D.I.Y._All-in-One right, thank you for the clarity. Great videos, have really enjoyed watching them all and learning something!
In my metric world "mils" typically is millimetre when talking linear and millilitre as per volume.
WHY DOES IT SAY DRY SEAL ON BUCKET IF ITS DUCK COAT!?!?!?!?!?!?!?!?!?!?
