RAIN GUARD PRO CR-0360 Micro-Seal Concentrate Makes 5 Gallons - Clear Natural Finish - All Purpose Deep Penetrating Water Repellent Protection for Wood, Concrete and Masonry Surfaces - Pro Approved

Ive been in the masonry trade and have been in business for approx 30 years . Majority of my work is restoration,repair,preservation,preventive maintenance with a little twist of new... In other words honoring and preserving masonry. With that being said, i can't express enough on the importance of keeping all exterior masonry surfaces " WEATHER SEALED ".. it's a MUST not an option,the harsh weather of elements , the beating sun of summer and harsh freeze and thaw of winter takes its toll ... There are so many proven benefits of sealer protection thats it's a " no brainer " period... I have done extensive repair projects to old and newer masonry in which it could have been avoided had the existing masonry would of been treated with a siloxane / silane blend sealer such as ( micro-seal )..All raw masonry new or old needs sealed.. It really is the final step in completing a masonry project.. I have kept track of projects not to mention field tested sealer applications at my shop location.. Guess what ?? They are still repelling water 10 plus years later, still resisting water absorption.. concrete block,brick,natural stone, thin artificial stone veneer, stucco mortar parging and concrete surfaces..Now keep in mind prior to a sealing treatment the existing masonry needs to be in stable condition and any repairs need to be addressed accordingly using a proper method etc.. Many problem issues i have been seeing lately is with thin stone veneer.. Which its use for exterior of homes is on the rise , although thin stone has its advantages in the building industry it is very problematic .. they absorb alot of moisture therefore tend to pop off or debond during the winter freeze thaw cycles etc.. not to mention excessive water wicking into interior wall systems creating a whole other havoc with rott and mold etc..Man made thin stone can also fade due to uv rays and yes it does.. keeping it sealed helps prevent that problem.. Now onto older masonry, what can sealer do to help ?? ANSWER = preserve it.. remember brick are very absorbent as well. You can still have a brick home in excellent condition and still wick water into the home.. repeated rain can and will do this due to not having enough time to evaporate or simply " dry out ", not to mention there may not be any weep holes for drainage of excessive moisture or lets not forget interior airspace between wallsystem and masonry that build up condensation .. Now by sealing you prevent the exterior water intrusion.. Excessive condensation can be remedied by the installing of venting where needed etc..Now im sorry for the long rant but as you can see im a huge advocate for saving and protecting masonry. Be proactive and keep it sealed, i can guarantee you that if you ignore it, you will incur future costly repairs that could of been avoided !!Yours in masonry , Bryan J Mabius ( mabius masonry ) my profile: custom mason with over 30 plus years in the trade, trade industry rep,guest vocational masonry instructor,structural bridge inspector , consultant

After days of researching options, I recently tried Rain Guard Pro on my outdoor concrete surfaces, and I'm thoroughly impressed with the results.The application was straightforward, and it dried quickly, leaving a clear finish that was almost imperceptible when dry. The last thing I wanted was discoloration on my driveway and sidewalk, and was pleased with the great results with Rain Guard Pro.The formula is quite thin and sprayed super well in my general yard sprayer. I’ve tried both this concentrated version as well as the ready-to-go version and they are identical. This formula is so much more convenient for storage and ends up being quite a bit less expensive as well.The following day I sprayed the newly sealed driveway with water and the beading effect was immediate, which assured me of its waterproofing capabilities. After getting wet, my spray lines were somewhat visible, but that’s not much of a concern for me (see attacehd photos).I’m optimistic that this sealer, with two spray applications going in opposite directions, will last and protect my driveway drop freezing moisture and salt this winter. I will update the review once the season passes and I have more long-term results.

I have a 450 sqft paver patio that I used this on. I think the product is fine. The issue I have is that it does not cover as far as they say it will. I bought 600 sqft worth of product that barely went 450 sqft. If you follow that application instructions, you will need double the amount stated on the product.

I did my new pole barn floor with this. And wow. If you've ever rain-x'd your windshield and seen the rain literally bead up and fly off without even using wipers, that's what your concrete is like after applying this. Absolutely awesome. It is ridiculously quick and easy to apply and it works exactly like it's supposed to. I think the only reason this isn't the go to product is its pricey. But honestly you get what you pay for. And it lasting 10 years and it won't wear off or need prep work to touch up in 10 years is worth it.My barn is 30x50 (1500) sq ft. It's a smooth hard trowel finish. I did one heavy coat and it did pretty much the entire 1500 sq ft. I say pretty much because on section I went back to do the second coat and realized it was impossible. The first coat (less than an hour before) was all it needed. It literally beaded up and wouldn't absorb any more. I had one tiny patch left at the end and had I not tried a second coat 5 gallons would've done the entire 1500 sq ft. I bought two 5 gallons though. So of course I did the sidewalk at my mother in laws and it was a rough brushed finish. Used a little more product but a half hour later dumped a bowl of water on it and they were amazed it just beaded up and ran off. The concrete was bone dry.Love this stuff gonna put it on my paver stones, wood shed floor, probably my trailer deck too. Gotcha some

I bought the 5 gallon tub of the product for $149.00.After I bought it I realized I could have bought 5, one gallon cans of CONCENTRATE for19.00 a piece. There by getting the same 5 gallons of the product for $100.00rather than $149.99 for the big tub.Usually its better to buy the larger tub but in this case IGot ripped off for $50.00 more in my opinion.Buy the concentrate not the big tub.
