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 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.

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?

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.

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.

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.

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.

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?

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.

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.

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.
