Questions & Answers

Q:Is the spray non-toxic

Answer This Question

A:  My guess is that when allowed to completely dry before your poultry is allowed inside or near the coop there would be no problem. For a definitive answer check the manufacturers website for the warning labels for the product.

A:  I’m pretty sure it is not non toxic, but would the chickens peck off bits of wood and swallow them? Maybe they would. Can you just put it on the outside where they wouldn’t get to it?

      A:  It depends on the surface. The product is meant to seal and protect. If it’s been on a while I’m sure it will. But if it’s fresh the paint may not adhere

      by|Jun 8, 2021

      A:  I have not but I see no reason why you can't.I actually used it over paint as a water seal on a deck.

        A:  I would select pressure treated wood for the garden and leave this product alone.

        by|Apr 23, 2021

        A:  This is from the SDS (safety data sheet) page 7.You should contact the manufacture for this type of information. Best to be safe. There are no data available on the mixture itself. Acrylate components of the mixture have irritating properties. Prolonged or repeated contact with skin or mucous membrane may result in irritation symptoms, such as redness, blistering, dermatitis etc. May cause allergic skin reactions with repeated exposure. The inhalation of airborne droplets or aerosols may cause irritation of the respiratory tract. Ingestion may cause nausea, weakness and central nervous system effects. If splashed in the eyes, the liquid may cause irritation and reversible damage. This takes into account, where known, delayed and immediate effects and also chronic effects of components from short-term and long-term exposure by oral, inhalation and dermal routes of exposure and eye contact.

        Perfect results
        I applied the product by brush ( 3" polyester/nylon) one coat. It rained overnight. Photo will show perfect results with the beading of water. Great product. Extremely easy to apply. I had a drop sheet down over composite decking and still got a few small drops on the floor. Clean up was simply a wipe with a rag. No staining of deck boards.

          Worked great
          It repels water like advertised. I used a spray gun to apply it onto a raised garden. I was worried because it went on milky white, then dried clear.

            Fantastic product!
            I bought this to use on my recently completed fence, which stretches hundreds of feet around my property. I read all of the instructions here online for this product very carefully and then followed them and the results were excellent. I made sure the temperature outside was right, I had sprayed down my fence boards first, I stirred the waterguard thoroughly, I used an electric paint sprayer to evenly distribute it up and down all the fence boards on both sides of my new fence, and it absorbed well and has been keeping the water off my boards. If I keep a sprinkler right on the boards they do start to absorb some water after half an hour of watering, but if it just occasionally hits the fence then it repels the water well. A couple of notes: I used nearly half the amount of product that was recommended. I had bought two of the large tubs and only dipped into the second one. Oh well. I'll keep it and use it next summer, as the product recommends reapplication every year. It took about three hours to do my fence with the one tub, mostly on the "low" speed of the sprayer, with someone to help me keep refilling the small paint sprayer container. Very happy with the product, ease of use, and the price point and would recommend.

              I put this on the untreated plywood siding I bought. It did not work at all. When it rained the plywood panel siding got damaged. That's over $200 in lumber that's ruined because of putting trust in this faulty product.

                Our 31 year old deck is 725 square feet and so this was a big project! We had used other products before but wanted a clear seal this time. We were extremely happy with the ease of application and how quickly it dried! The deck looks fresh and clean. We’re glad we chose this product!

                GREAT product
                I used this product on both the old wood and new wood after replacing some deck boards on on my deck. The old boards are over 20 years old and they were previously painted. Removed the old paint from the old boards. So far its been wearing well and it is doing it’s job on both the old and new wood. Then i used it on a new picnic table and benches that i made to replace some old outdoor patio furniture. I don’t normally write reviews but this product has performed impressively. You have ti letnit dry before it gets rained on. But as long as you give it dry time, it performs.

                  Hi there. We're sorry to hear this. We do not recommend applying two coats of this product as this will likely result in product failure, especially in areas with high moisture and little or no direct sunlight.

                    Totally Useless as Waterproofing Agent
                    I would, of course, give this product a zero rating if possible. After much time, effort, and expense I finally finished my pool pump enclosure in redwood. Being an exterior structure, I wanted to seal the wood and make it as waterproof as possible. Home Depot no longer stocks Thompsons so I chose Olympic Waterguard Clear Sealer. Application was easy, since I used my spray gun. Over the course of one week, I applied three more light coats. Much to my dismay, the overall appearance took on an orange cast. Any school kid can tell you red combined with yellow make orange! Not the effect I was after. Next came the water test. After everything was completely dry......I waited another week. I then sprayed a light mist on the project with my garden hose. Sure enough, the water beaded. Fantastic. I then let the water sit for 15 minutes, took a terry towel, and wiped down the project. Again dismay. The water had soaked into the wood!

                    We are sorry to hear that you are disappointed in the performance of our product. We do not recommend more than one coat of application with Olympic Waterguard. To properly adhere and cure, Waterguard must be properly applied in one even, thin coat. Please give us a call at 1-800-426-6306 so we can help provide potential solutions. OlympicPaint

                      Easy to apply. Easy clean up. Changed the hue of the redwood just a bit but not in a bad way. Put some water on the sealed wood and beaded up as advertised. Not greasy or oily like other products I've used in the past. I would recommend this product.
