Is this safe to use on a surface that will get extremely hot like a chininea?

Is this safe to use on a surface that will get extremely hot like a chininea?
Asked by: BayBay
Hello. The surfaces that our products are applied to should not experience temperatures past 110 degrees Fahrenheit. Our Clear Multi-Surface Waterproofer product is fine for use on the outside of traditional house chimneys, but may work on the outside of the chiminea. Regards, Thompson’s WaterSeal Customer Support

How best to apply waterproof? Over or under a primer?

I would like to spray waterproof onto new plywood underlayment to protect against moisture in an entrance. Should I spray it directly on the wood and then apply primer to adhere self stick vinyl tiles or prime first and then spray the underlayment?
Asked by: 242
It depends whether you want to protect the surface or the primer. It seems like you plan to paint over the primer since that's what a primer is for. In this case, you should make the waterproofer the last coat.

12 oz. Clear Multi-Surface Waterproofer is rated 4.8 out of 5 by 10.
Rated 5 out of 5 by from Very Nice These cans are perfect for the smaller projects and the hard to reach areas. They work perfect and are just what you need for those planters, underside of railings and steps. I've used them during construction to get the pieces that are going to be the hardest to get later. These will not disappoint for sure. Get them and you will see. Happy waterproofing.

Rated 5 out of 5 by from Great waterproofer and easiest possible application This 12 oz. Clear Multi-Surface Waterproofer works great. I've used it in the past on a wooden swing which required annual application because it was weather-exposed year round. I also applied it to some leather workboots--but be aware it may change (darken) the color. Dries clear. I don't see how it could be easier to apply a waterproofer than aerosol spray.

Rated 5 out of 5 by from Convenient Spray New way to apply an old classic water sealer. This seems like the old school clear liquid waterproofer in an easy to use spray can. This is really good for small projects. A can will cover about a 4'x8' area fairly well. With the convenience you pay the price. I can see doing a dog house or bird house with this product because of the prep and cleanup time saved. I sprayed the concrete area where my garage door vinyl seal contacts the floor and let it dry a couple hours before closing the door. The next day I directed the garden hose at the seal to simulate a hard rain with wind and it helped repel the water really well. I will repeat this treatment every couple months because it's quick and easy.

Rated 5 out of 5 by from Spray Waterproofer I needed to waterproof my front brick steps I just finished repairing with mortar. I tried other sealers but for some reason they didn't fully seal the steps and that's why I had to repair them. I waited for a time, when there would be no rain, at least for a few days. The steps were swept and dry. What I really like about this product is that I could spray it on which was much faster than using a brush on sealer. It has poured and rained several times and so far the steps still look good.

Rated 4 out of 5 by from REALLY GOOD WATERPROOFER NOW IN A SPRAY CAN Thompson's makes really good products that I have used in the past and this clear multi- surface water proofer is no exception. The ability to spray on a water proofer to several different surfaces is easy, quick and hassle free. I applied it to a gray cement statue that I put under a tree in front yard. The water beads off of it and even dirt and debris slide off. I am hoping this helps the statue last longer before it becomes brittle, etc.

Rated 5 out of 5 by from SOMETHING THAT REALLY DOES WATERPROOF TERRA COTTA! Finally something to REALLY waterproof terra cotta and it's a 1/3 of the Walmart price and a 1/2 of any Internet price!

Rated 5 out of 5 by from love I used this on a bunch of different surfaces on my back deck to see how this would do. I have used Thompsons products before so I didn't think it would be an issue. It wasn't. Applied easily, sprays on evenly, great coverage and a little spray goes a long way. I don't think you can go wrong with any of the Thompsons water proofing products, they just work and work well.
