MasonrySaver Heavy Duty Water Repellent

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 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 resistances 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. Does not change 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 then 30 minutes to seal the entire driveway.

Water Repellency: 8

– We waited a day after application 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 $139.99 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 of $.20 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 state: “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 then fair as well.

Top choice for sealing and water proofing any existing concrete surfaces.

    You used 10 gallons for your 1000 sq ft test. Price was $140 per 5-gallon pail. How could you conclude that cost was 14 cents per foot?? Are you sure that the cost category warrants a rating of 9 ? Please help me to understand. Thanks.

    • Concrete Sealer Help says:

      Hoytbon, looks like bad math on the sq. footage. I will check the project notes and make sure.

      • Ken says:

        16 weeks ago and you still have not replied to his inquiry of the cost you stated. I find that to be a bit of a letdown in response to people who are interested in the review of products you have tested. Are you going to answer or not? How much did you use and at what cost per square foot? I would like to know because I am in the process of doing my driveway and as a consumer would like good, solid information from a site such as this.

  2. Jen says:

    Is it ok to use this over an existing sealant….and what do I add to make this skid proof since I am using around a pool.

    Thank you

    • Concrete Sealer Help says:

      Jen, I am not sure. For this product to work it needs to be able to penetrate. It the old sealer does not allow this then it will not work correctly.

  3. Charleen says:

    I do not see any info as to whether or not this sealant will bubble up (and off) on concrete due to hot tires from cars pulling into a garage and parking. What can you tell us about 'hot tire' and this product? Thanks!

  4. Steve says:

    I'm looking for a sealant to apply to brick coping around a pool. Bricks are around 11 years old, with cracking in some limited areas. So, while I understand there's no silver bullet, looking to apply something heavy duty. Would you consider MasonrySaver a good option? Thanks

  5. Mr. Chance says:

    I have stamped concrete and need to reseal after 8 years of not resealing. I am in tree hugging California. I am going to Arizona shortly and want to buy the best sealer and I will add the grit. It original was a laquer base. If it would be better when I go to Arizona I will buy it there. I just need to know what is a longer lasting than the garbage we can buy in California? Thanks for your help.

    • Concrete Sealer Help says:

      Mr Chance, I am not sure on the VOC laws being different in AZ from CA. I would look at the SuperSeal VOC. It can be shipped to CA.

  6. Diver_Medic_Tech says:

    I am getting ready to coat a 3600 sq. ft. garage/shop. I am looking for a product that will mainly help keep grease and oil from penetrating the concrete and causing lasting stains. Will this do the trick?

  7. Stanley says:

    Will the use of the product leave the driveway slippery?

  8. Sam says:

    After the 7 years, do I just reapply the same product, or do I need to use some sort of remover first?

  9. FRANK ARCARO says:


    • Concrete Sealer Help says:

      Frank, You could use the Masonry Saver for the block sealing. You can order this online or call manufacturer for help with this.

  10. Bob says:

    In addition to oil stain protection I would like a sealer that provides enhances the look of pavers such as those that give a wet look. Will Masonry Saver do this?

    • Concrete Sealer Help says:

      No this will not enhance the color.

      • Slav says:

        Is there some other product that could be used in combination with this one to enhance the look? I applied this one last night, and you can't tell that anything's been done. I wonder if it's too late to do anything else.

        • Concrete Sealer Help says:

          Too late now. Enhancing sealer would have to go on first.

          • Rich Z says:

            hi, Enhancing sealer? Same penetrating qualities? Details please?

          • Concrete Sealer Help says:

            Details as in? This product does not change the appearance not should you use an enhancing sealer for your surface and conditions.

          • Erik says:

            You mean an enhancing sealer would go on one day before the masonry saver and a 2nd day the masonry saver could go on after that? If so which enhancing saver would you suggest? Thank you

          • Concrete Sealer Help says:

            You cannot add an enhancing sealer then use the Masonry Saver over top of it. It will not soak in.

  11. Joe says:

    Is this good for a brick chimney or would recommend another product? The house is waterfront, if that makes a difference?

  12. Judy says:

    Is this product recommended for use on roof tiles to seal against moisture? I am trying to eliminate mold build -up on my roof. If not can you recommend another product?

  13. Carmen says:

    Can you paint over the sealer to enhance a look?

  14. Masonry NY says:

    Are these guys from NY, i need help on masonry in New York.

  15. John H. says:

    I am looking for the best stain blocking sealer for my regular poured concrete driveway. I have a lot of trees that drop leaves and tassels on my driveway and if left alone will stain the concrete black. I used a pressure washer to remove all of the black stain and now I want to seal the concrete to prevent the stain from coming back. What's the best sealer to use?

    • Concrete Sealer Help says:

      Sealers cannot stop mold or black stains from coming back. They can make it so it is easier to clean down the road. This product would help with that.

  16. Rich says:

    Looking for a great sealant now that i can paint or coat over 2-3 yrs in future. My conditions::: Northern Michigan, untravelled , 90 day cured concrete ,1800 sq ft recenty acid etched trowel finished floor and brushed approach slabs. Building is 1.6 miles into the woods on dirt road… Hot Tire issue probably a non issue here. Radon seal gets some high ratings. Any suggestions welcome. Thx rz

    • Concrete Sealer Help says:

      This product will work for this.

      • Rich Z says:

        thank you, Is this product any better than the many sealers out there at about the same price? Have no desire for shine, but a color enhancer or whatever uniform grey look I could get with a surface penetrating / strengthening sealer is very desirable. Not interested in the epoxy process.

  17. Montana Bob says:

    1. What State do you live in?
    Western Montana (warmer than Eastern Montana less snow).

    2. Interior or Exterior concrete surface?
    Exterior (majority under a carport, balance is exterior exposed to weather

    3. Vertical or Horizontal application?

    4. Change or enhance appearance (gloss or wet look) or no change of appearance?
    Wet Look

    5. Type of surface:
    New concrete driveway (3,500 pound mix, 6″ thick slab, epoxy-doweled to existing garage floor and re-bar reinforced and brushed surface)

    6. Purpose:
    To prevent spalling, salt, de-icer and rain damage.

    ***Of particular importance is that the surface is protected against staining by oil, gasoline and diesel fuel.***

    Thanks for your help!

    Montana Bob

    • Concrete Sealer Help says:

      Wet look sealers will not work for regular poured concrete. They are for decorative surfaces. This product above will work for you and will protect form staining, oil, etc.

  18. Pep says:

    Can you use this Sealer on a vertical exterior brick wall to stop water penetration to other side of the brick and stop the run down of the water on the "inside" side of the brick?

  19. Mr. Baker says:

    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.

    • Concrete Sealer Help says:

      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.

  20. Misty says:

    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? I wanted the patio protected but with NO change to the color or look, no sheen. What can we do?
    Any help is appreciated!

    • Concrete Sealer Help says:

      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.

  21. Mike says:

    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?

    • Concrete Sealer Help says:

      Sorry but you will need to ask Defy on this one. The chemical makeup of the two may not be compatible.

  22. Miya says:

    Can this product to be shipped to California? Thank you.

  23. Sheila says:

    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?

    • Concrete Sealer Help says:

      This is a penetrating sealer. Does not have a gloss os is slippery. Will not work though for decorative stamped concrete.
