The MasonrySaver Heavy Duty Water Repellent is one of our top sealers for waterproofing concrete based on performance and price. If you have any questions or have used the MasonrySaver Heavy Duty Water Repellent product, please ask below in our Q&A area. We are here to help!
MasonrySaver® (Also known as “Defy”) All-Purpose Heavy Duty Water Repellent is a modified siloxane-based product designed to penetrate deeply into most masonry and concrete pores. 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 greater resistance to the deteriorating effects of road salts and de-icing chemicals. This 100% breathable concrete waterproofing product is a great choice for both 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.
MasonrySaver Heavy Duty Water Repellent Scores (1-10)
Ease of Application: 10
– We applied the MasonrySaver Heavy Duty Water Repellent to a 1000 sq. foot driveway using a plastic pump sprayer. The sealer goes on milky white and dried clear in about 20 minutes. It took less than 30 minutes to seal the entire driveway.
Water Repellency: 8
– We 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 very reasonably priced at $219.99 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. We actually used 7 gallons for a cost of $.30 per foot.
Durability/Spalling After 2 Years: 9
– After 2 years the MasonrySaver Heavy Duty sealer still performed well with the beading water test. There was no pitting or spalling of the concrete.
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
– We really like this sealer. It is easy to apply, durable warranty, and beads water well. Cost is more than fair as well.
Top choice for sealing and waterproofing any existing concrete surfaces.

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.
I am looking to stop water from coming inside a brick home and want a dealer to stop it at ground level will your product stop it?I have used Thomson’s but no luck.
Sealer
A sealer cannot prevent water from seeping up through a floor. Sealers are for preventing water from soaking into a surface, not out.
I have just had a new home built. I am looking for a product that I can use to seal the garage floor with that will not allow oil and grease to be absorbed into the new floor. The concrete was finished in a very smooth finish.
The Masonry Saver Heavy Duty would work well for this.
Live in Georgia near Savannah, so no snow. Want a product to protect concrete and inlayed brick every 20 feet from staining from pine straw. If it lays on the drive more than a day, I have brown marks. Once removed, the sun fades the marks or I can remove with power washer. Do I need a acrylic coating or a penetrating siloxane or a combination of both.
A sealer will not stop the straw staining. You will still have to wash it off. It will help it though from penetrating deep in and will make the cleaning easier. Try the Masonry Saver Heavy Duty Water Repellent.
I would like a Brick edged pond with the water coming up to half the height of the Brick. Would your product be successful in stopping the water being soaked up by the Brick and the level falling as a result? Thank you.
Sorry but no, a sealer will not work in a scenario that has constant water like a fountain to 100% seal our water. It will help but not stop 100%.
Then what would you use?
I have a colored and stamped drive that I’d like to seal without changing the appearance. Sounds like this penetrating sealer would work but I saw a reply in the list that said no, is that correct?
A clear penetrating sealer does not work well for stamped concrete. That is typically a decorative sealer and that means it will enhance the appearance. https://www.concretesealerreview.com/best-stamped-concrete-sealer/
what is the concentration of silanes/siloxans in the product? Is it available in 1 gal containers? How much does it cost? Where can it be purchased in MA?
You would have to ask the manufacturer directly for help with the % of content. It does come in gallons and you can buy online.
I have a concrete patio and in-ground pool apron that is at least 30 years old. The aggregate is visible and the surface is somewhat rough. Would like to seal/protect and make it easier to clean with a long lasting product. What do you recommend?
State=Rhode Island
Exterior
Horizontal
No visible change necessary
This product would work.
I want a non darkening matte sealer for outdoor concrete pavers that gives me protection from staining – is this the best option?
Thanks
Yes, this would work very well.
Will this seal against rust stains.
It would help so the rust stain could not soak in deeply.
Can this be used over a stained garage floor?
Not over a stained floor.
I need to apply a brick sealant to the exterior brick siding of my house – from the first layer of brick that sits on the slab foundation and going up about 14 inches or so – to prevent water seepage through the brick to the sheetrock, insulation, etc from occasional hurricane flood waters that come from the tidal creek behind our house and sits against the brick siding for hours to several days until the rivers recede. Is Masonry Saver Vertical Brick Water Repellant the right product to seal and waterproof the brick siding or is there another product… Read more »
I do not believe any sealer will stop flood waters. It will stop rain, but not flood water sitting against it for numerous hours.
We have a stamped concrete driveway porch sidewalks that has been seal almost yearly Will this sealer work and help restore the color
No, this product does not enhance the appearance. You would need a wet look sealer. Post a picture of the current condition.
In researching Masonry Saver Brick Water Repellent, I see the words “Chimney” or “Vertical” in the name as well. Are these actually three different formulas for different applications? We have (likely) water intrusion from vertical brick work on the side of our house. Storms that blow in from that direction seem to intrude into the attic via those bricks.
There are not different versions. The MS Brick Water Repellent is for any brick vertical surface.
I have a finished/grouted pool deck of travertine and love but it has lost its gloss. I did a sealer about a year ago and I looked nice but didn’t hold up maybe a few months. I did put it in light as I am very afraid of turning it milky over time. So I am looking for a product that won’t do that and give a sheen
Try Super Seal 25.
Can the Defy MasonrySaver Heavy Duty Water Repellent be applied over a concrete pool deck that is already coated with acrylic paint and texture?
No.
Is there a difference between the Heavy Duty Masonry Saver and what looks like the same product but has the Defy label on it.
Same. They renamed if from Defy to Masonry Saver.
Can I apply this over previously sealed stamped concrete?
No.
I live in Florida…how is it on cement pavers around my salt water pool…. also any issues doing my driveway also made of cement pavers
This will seal and protect pavers with no issues and works very well as long as you are looking for a sealer that does not change or alter the appearance.
I live in Florida with lot’s of sun, rain and mold. How does your product hold up in this environment?
It is not our product but it does work very well in Florida.
Please give your opinion on Lifeguard Waterproofing Sealant for use on cultured stone.
Never heard of it or used it.
Is this sealer good for brick walls as well?
You would want the Masonry Saver Vertical Brick Water Repellent for brick walls.
Can u buy this product at lowes or home depot
No.
I live in San Francisco California. I want to seal cracks in exterior concrete wall of house and stairs to
prevent water penetration in cracks with no change in appearance. What is the best sealant to use?
A concrete water repellent will not “seal” large cracks. It will seal the concrete so it prevents the water from going through the concrete. It also will not change the appearance.
Can this product be used indoors to seal concrete floor, does is give off frumes
Yes it can. Low odor water-based formula.
We have a 18 year old driveway that has cracks and in some places is worn down to a surface of visible rock. Power washing removed a fine too layer. What do you suggest for repairing and protecting?
We live in Alabama and the driveway gets at least 6 hours of sun.
I remember that when poured this concrete a had a fiber added to the concrete and when finished it had a smooth surface.
Thanks for your help.
Hello, you cannot repair this. You can seal so it does not get worse. The Heavy Duty Water Repellent will work.
Can I use this on my paver driveway to help protect from stains from the occasional old car or motorcycle? I don’t want the “wet look” or for it to be slippery.
Yes, it works to protect from oil stains. Does not give a wet look.
How many gallons of Masonry Saver (Defy) are needed to do 600 square feet of concrete pavers around a pool deck? The product information states that one gallon will cover approximately 75-150 square feet, and two coats are required. I imagine the second coat would could more square footage. Please advise.
Heavy Duty Water Repellent or Paver Sealer from Masonry Saver?
Paver Sealer
Ok, wanted to make sure as this review is about the Heavy Duty. You will need about 6-8 gallons for the two coats of the Masonry Saver Paver Sealer.
I want to seal the concrete under a fountain. Will this product work if it is under water all the time? Does this product come in colors?
No and no. Sorry.
Does this product make the surface slippery? Is it a matte finish? Do you recommend for newly poured stampcrete that it cure for 28-30 days before applying?
This is a penetrating sealer. Does not have a gloss os is slippery. Will not work though for decorative stamped concrete.
Why would it not work on stamped concrete? I have colored stamped concrete. Is this typical for sealers in general?
Sealers for stamped concrete needs to be decorative, not penetrating.
Can this product to be shipped to California? Thank you.
I belive so.
Last year I used the Behr premium sealer, but several areas of my brick and mortar exterior walls need a sealer again. I want to use the Defy product. Do you recommend I just use the Defy on the areas that need a New application, or can I use it everyone and apply over the remains Behr sealer? Will Defy work when applying over another sealer?
Sorry but you will need to ask Defy on this one. The chemical makeup of the two may not be compatible.
We had a large, 20 foot, modern patio poured with voids for border shrubs and raised portions for gardens and a fire pit. It was acid stained a very light grey. It was beautiful. Then our contractor sealed it with, …?…, and now it is several shades darker, reflective, much hotter in sun, slightly glossy and I hate it. It completely changed the look I was going for. He clearly should have used something like this MasonrySaver. Is there anything we can do? Would it be difficult or safe to remove somehow? If so would it also remove the stain?… Read more »
It is normal for acid stain sales to enhance the color. As for removing, without knowing what brand and type of sealer that was used, it is impossible to say how to remove it. Need to find that out.
We have a 900-sq ft concrete balcony, poured over galvanized sheathing. It's exposed to Chicago weather. (1) Will this product protect from water seeping through the concrete? (2) Will this product yield a surface with good enough traction for foot traffic? One answer below said the treated surface "should not" be slippery. Sounds doubtful.
This is a penetrating sealer so it does not create a film that would cause it to be slippery. Yes it does help the protect from water seeping through.
