MasonrySaver Heavy Duty Water Repellent
MasonrySaver® (Also known as “Defy”) All-Purpose Heavy Duty Water Repellent is a modified siloxane-based product designed to penetrate most masonry and concrete pores deeply. Unlike acrylics, silicones, and other waterproofing sealers that remain on the surface and trap water vapors, this masonry waterproofing product allows deep penetration of its active ingredient of up to 1/4 inch or more. This proprietary blend of silanes and siloxanes creates a “SaltShield™” barrier on concrete surfaces for more excellent resistance to the deteriorating effects of road salts and de-icing chemicals. This 100% breathable concrete waterproofing product is an excellent choice for horizontal and vertical above-grade surfaces.
Concrete Sealer Ingredients: Blend of Silanes and Siloxanes
Concrete Sealer Type: Invisible Water Repellent. It does not change the appearance.
My MasonrySaver Heavy Duty Water Repellent Scores (1-10)
Ease of Application: 10
Using a plastic pump sprayer, I applied the MasonrySaver Heavy Duty Water Repellent to a 1000 sq. foot driveway. The sealer goes on milky white and dries clear in about 20 minutes. It took less than 30 minutes to seal the entire driveway.
Water Repellency: 8
I waited a day after the application and then did a water test. The water did bead up well and did not penetrate into the concrete.
Cost per foot: 8 (see note)
The MasonrySaver Heavy Duty is reasonably priced at $249.99 per 5-gallon pail. We used 10 gallons of the sealer for our 1000 sq. foot driveway. This came out to $.14 per foot.
Note: Mistake on Calculation. I used 7 gallons for a cost of $.35 per foot.
Durability/Spalling After 2 Years: 9
After two years, the MasonrySaver Heavy Duty sealer performed well on the beading water test. The concrete did not pit or spall.
Warranty: 8
MasonrySaver Heavy Duty Water Repellent comes with a 7-year warranty that states: “All-Purpose Heavy-Duty Water Repellent will exhibit a water repellent effect for seven years from the date of application if applied according to label instructions and if minimum application requirements are met.”
Overall Score MasonrySaver Heavy Duty Water Repellent: 8.7
I really like this sealer. It is easy to apply, has a durable warranty, and beads water well. The cost is also more than fair.
It is the top choice for sealing and waterproofing any existing concrete brick surfaces.

How long before you can drive on it after you seal with masonry saver heavy duty water repellent?
2-3 hours after it dries.
Do you know how many times stored, unused, MASONRYSAVER HEAVY DUTY WATER REPELLENT can be frozen and, still be usable?
Never can be frozen.
We have a large, elevated concrete decorative deck. 2 coats of an acrylic copolymer sealer was applied last year, however the deck continues to leak. What would you recommend for the best waterproofing gloss sealer to be applied a this point?
Sorry, but no gloss sealer will 100% seal out water.
We’re looking to seal an indoor cement floor for an art studio. We used an industrial cement grinder, then applied two coats of decorative cement stain. We’re looking for a roll-on sealer with high gloss that richens the color. We’re not pros. What do you suggest?
You need more of a clear coat top coat like this: https://www.restore-a-garage.com/restore-a-garage-epoxy/restore-a-garage-clear-top-coat/flypage.tpl.html
Can we use a top coat without a previous coating, or is this to use over epoxy? Epoxy would be great, but I’ve heard horror stories about applying it as a non-pro.
You can use a top coat over your stain.
You could use a Clear epoxy.
Do you suggest a cleaner/ detergent for cleaning concrete with / prior to power wash ?
That would depend if you need to remove any stains or just dirt. Cleaners are specific to the stain(s) being removed. If just dirt, then pressure wash with water only.
15 year old concrete driveway and interlocking concrete brick retaining wall will be power washed and sealed . Which product? How long after washing can they be sealed ?
The Masonry Saver or SuperSeal-M would work very well. 48 hours after prep to dry before sealing.
Would this work for 100 yea old brick and mortar?
Yes.
Is it ok to apply a second coat of Masonry Saver heavy duty water repellent one day after first coat?
We would not do it. More is not better and you could creat issues.
OK — THANK YOU
Yesterday, I sealed the concrete in my new 30′ X 40′ garage using Masonry Saver Heavy Duty water repellent. I waited the recommended 30 days after the concrete was poured before doing so to allow for time to cure. My question is, is it OK to give it a second coat?
I purchased 10 gallons but only used 5 gallons. Would like to use up the remaining by giving it a second coat, but did not know if this is wise or recommended.
will the sealer work on the brick mortar also?
It should.
I have a mixed stone retaining wall…what product would you recommend as a water sealant?
Super Seal-M or the Masonry Saver Heavy Duty.
Hi I need a product that will work on brick that’s been painted. Any suggestions?
It is not possible to add a sealer over a painted surface.
What other waterproofing options are there? Perhaps a liquid rubber or something? I probably need to rebuild my wall but need a temporary solution for waterproofing even if it’s ugly.
None that we know of will work over paint beside another paint.
Want to do the new garage floor once it’s poured. Can deep penetrating sealer be followed up with epoxy coat? Plan to color the existing floor later and want them to look the same.
You cannot apply a sealer before an epoxy. It will repel the epoxy and it would peel.
I have a brick veneer home and am adding on to it with brick veneer coming off a outside wall 90* two questions. I would like to leave the current outside wall as an interior wall in the new room, so I want to seal this wall. Also, i would like to seal the remaining outside wall so that we have no moisture migrating into the new room. will using this sealer work both places? Also, what prep do i need to do to the existing brick before applying sealer, just spray with bleach and wash off?
You would want the Masonry Saver Brick Water Repellent for this. Just pressure wash to clean. Do not use bleach.
Can this product be applied with a roller? And if so, are there any specific instructions to do so?
Thank you!
Spray it on with a pump sprayer.
Our home is almost six yeasts old. We now know how so many sacks of concrete was returned when brick layers finished.
The mortar has very little concrete mixed in which is resulting in water leakage.
Can you please help us in which product to use. To fill in cracks waterproof
Thank you for your time and help
You can seal the bricks but you cannot fix the mortar problems with a sealer. No sealer will work to fill in cracks.
I d like to limewash my kitchen splashback, including behind my cooktop. Would MasonrySaver heavy duty be the right product? I want to be able to wash the wall as often as need be. Also, I don’t want the colour of the limewash to change when I add a sealer.
None of the products we review can be used indoors and we do not have any experience with what you are trying to do. We only work outside.
try Simple Green or Lime Away. They sell at Home Depot or Lowes or grocery stores.
Those are cleaners, not sealers, and will not work for what she wants to do.
Can you stain the exterior concrete patio first, then use this sealer on top?
It is not possible to apply a penetrating sealer like the Masonry Saver over a stained concrete surface. You would need a filming decorative sealer.
I live in Minnesota and my two stall garage floor is in horrific shape. It is 400 sqf and I am going to try to grind it back to life. Will 3 gallons (Defy) be enough for fresh concrete, or should I just go for 5, and can I just reapply any extra at a later date? Thank you for your time.
3 gallons should be enough for this.
How many coats?
Typically just one coat is needed.
Which sealer do you recommend for outdoor/patio new travertine pavers?. Looking to keep original travertine color, hence not wet neither dark, thanks
The Masonry Saver Heavy Duty would work well.
Does the temperature need to be above a certain number to use this product. Just poured a new floor for a detached garage and it’s Winter right now. Our temps have ranged from 30s-60s lately. Average could go down in the 20s at night and only 30s in the day.
50+ degrees.
