Rain Guard Wood Sealer Concentrate | Makes 2 Gallon | Protects Wood from Water Damage, Rotting, and Stains | Water Based Silane/Siloxane | Eco-Friendly | VOC-Free | Natural Finish

I bought this to repair a leak in my roof (double-layer of composition shingles). This little bottle fixed my roof leak....plugged the hole that was most likely several loose nails not connecting fully with tar paper underlayment. I highly recommend this product to seal virtually anything. I diluted it per the instructions and sprayed on with garden pressurized sprayer two coats applied 40 min apart in dry weather about 45°f. I had tried 2 other liquid rubber waterproofing sealers, which doesn't work. I never write reviews. This is authentic and meant to help the next handy homeowner save some major $.

While you can spray this stuff on, I went ahead and carefully brushed it on our chickens 4' x4' x 5' ish cedar coop. It works, as we have had atmospheric rivers off and on recently, no cracks or leaks, water beads off even after several months of rain. Still have a bit left in the container for next year.

Easy to mix, good instructions. Said it was for interior use . Had door open, fan going but didn't realize it had a lot of fumes (have no sense of smell so couldn't smell it). After first day, when I stopped and went in house, felt sick, lungs hurt, sore throat. Hopefully it didn't do permanently damage. Had there been a warning on it, would have followed it, but since it is for interior and no warning, had fan and open door as I did for painting. It did pool in places but worked it out. Results look ok.

My tool shed had some water leakedge and the floor took forever to dry up now after putting down the sealer 2 times it holds any spills above the floor easy to clean up

I believe this product will do what it is designed to do. Unfortunately, the spray bottle that is provided to dispense the solution is deeply flawed. I purchased two spray bottles of the Rainguard water sealer and both spray bottles are defective. The spray option only semi-works correctly when the bottle is held in a horizontal position to the surface you are trying to cover providing less than optimal coverage. If you dip the spray bottle even slightly the spray pattern falters and the liquid drips aggressively out of the spray handle. I eventually gave up on the spray and used the stream option and a brush to distribute the solution. This didn't stop the leaking from the handle, yet allowed me to concentrate more solution and work it into the grain of the plywood. Pro: - Appears to offer the advertised sealing and protection--according to the product instructions it will take 7 days to fully cure Cons: - The provided spray bottles are a detriment to properly applying the wood sealer - Spray bottle usage is frustrating and inhibits proper application directly contributing to the lower satisfaction rating Bottom-line: With extra effort, I was able to cover the intended wood surfaces. The product is expensive enough a better quality spray bottle should have been provided. I've saved a spray bottle and will contact the manufacturer to see if they are interested in getting to the root cause of the problem. I will update my review in a couple of weeks as to the performance of the sealer and resolution if any from the manufacturer concerning the spray bottles. Update: I tried contacting the manufacturer directly and through Amazon with no luck. So customer service is one star. I have had a wet winter giving me ample opportunity to observe this product in action. Rain Guard works most of the time yet can fail when the wood is heavily saturated from prolonged rain. I rate the product 4 stars. So my recommendations is to skip the spray bottle and you should be satisfied with the products results. Overall, I will leave my rating at 3 stars primarily for lack of manufacturer interest in improving their spray bottles.

I used this product to treat Douglas fir plant shelves that get wetted at least once a day. After a year, water still beads up on the tops. I also used this on cedar fencing and have seen no sign of termites, unlike my neighbors, literally all of whose fences are turning to sawdust. I didn't want to repeat their mistake since termites never stop in our mild climate (coastal southern California). I treated all of my wood with borate and then used this sealant to prevent the solution from leaching out. The fact that it waterproofed the wood was a huge bonus. The treated wood sun-bleached normally and doesn't look any different than untreated wood. This product and the small effort to apply it should more than pay for itself by extending my fence's lifespan, and I plan to do a maintenance re-coat in a couple of years. All in all, it's been well worth it.

I ordered two 32 oz bottles of RAIN GUARD WOOD SEALER for my dock and deck. I have used RAIN GUARD CONCRETE SEALER and have been pleased with the product. my order arrived it in two different containers, one was the regular black bottler with 32 0z in it. The second was a white bottle shape differently but with the same label showing 32 oz. I have a 1 gallon sprayer marked for 16 oz to mix the product. the first bottle had 32 oz as advertised the second one was 4 oz short, 16 and 12 oz per gallon. as a result i was 100 sq ft short on my sealing job and will need t order another bottle. Are all of the new bottles going to be under filled? Update I contacted Rain Guard Water Sealers, explained the problem of short volume to Nicholas Parker Customer Support and he was very heplful. he had RAINGUARD Mmail a replacement 32 oz bottle of RAINGUARD WOOD SEALER to me. arrived in three days. Thanks Nicholas. New rating 5 STARS in customer service.

After a rainy season, wood on fence looks good!
