Hello, I need to waterproof 3 1/2 inch thick 4 feet by 1.5 feet MDF boards. They will be installed inside under a big stone. Can I use this product? I am worried because you specifically say it cannot be used indoors. Thank you

Asked by: Ramz444

Thank you for your question, we apologize for the delayed response. No, unfortunately all of the Thompson's Waterseal Products are for exterior applications only. Regards, Linda @ Thompson's Waterseal Customer Support

I purchased a Yardistry Pavilion several months. In checking with Yardistry, they recommend Thompson's water based sealant. After reviewing your reviews, I don't see very many happy customers. Is this the right product for this product?

I want to seal my concrete bird bath.  Is this product non toxic and safe for this application? Thanks

This product is a water based sealer and will work for sealing the bird bath. It must given drying time as per label before being put back into use.

I've got a slate tile covered deck.would this product work for natural slate

Asked by: Slate guy

Hello. Bare slate is an approved surface. Do a wipe down within 5-10 minutes of application to remove any excess product that does not absorb. Regards, Thompson’s WaterSeal Customer Support

I have a insulated garage. I just want to be extra sure that no moisture go from outside brick wall to the inside of wall. Would it work for this purpose?

Asked by: GarageGod

Hello. You can use our product on the outside of the brick wall, provided it has no existing coating/product on it. Our product should seal the outside surface against any moisture or water. It will not seal any water from the inside wall though. Regards, Thompson’s WaterSeal Customer Support

Thompson's WaterSealer Waterproofer - Multi-Surface - Clear - 3.78-L is rated 2.8 out of 5 by 68.

Rated 3 out of 5 by ecolen55 from Has the formula changed? I had some 5 or maybe 10 year old Thompson water seal. I put it on with my old Thomspon sprayer and it worked great. However, I swear the sealer was clear. Purchase a new can of sealer and it was milky and was very difficult to spary on my fence. The application was very blotchy. It look terrible but as it dried the apperance improved. Still have some sticky areas and wasted a lot of sealer because of how it sprayed.. I still recommend Thompson's water sealer because I have used it over 30 years with no problem. Makes me wonder if its my sprayer or if its the product. I may have to do the fence again to ensure proper coverage with a new sprayer and product.

Rated 5 out of 5 by MKro from Very Effective on Older Concrete Pavers I was looking for a product to bring some life and colour back to an older patio made of concrete pavers. I had tried other products with limited success. Thompson's Multi-Surface did the trick. It is cheap and very effective. It improved the colour while sealing it. To prepare all I did was used a pressure washer. I tried to roll it on with limited success so quickly discovered that spraying it with a pump sprayer worked best. I did find it useful to use a paint roller to even out the spray. Two coats were necessary. There are also good videos on Youtube to show you how to apply.the product. I have also found that the product may go a little milky if rained upon early after the application but this will disappear

Rated 1 out of 5 by Jennyd from Very disappointed We power washed and cleaned our deck and it looked brand new. We waited a day to be sure it was dry and applied this clear seal and I am so disappointed. This was 3 days of work and it looks horrible!! I have used this product for 30 years and have always loved the way it brightened and refreshed our deck. How do we fix this?

Rated 5 out of 5 by Stevi from Finally waterproofed Due to many years of illness, sealing of our deck never got done. Just found someone to complete the process after a good pressure cleaning. This poor abused 10 year old deck is now looking like it was just built and sealed. Am so happy with how Thompson's performed.

Rated 1 out of 5 by Thomas from Thompson Needs to Develop a New Formula My experience is the same as the other recent reviews, i.e. leaves the concrete sticky and blotchy. Used two gallons with a garden sprayer as recommended on the can. When I ran out and had to go purchase another gallon, the nearest store didn’t carry Thompson’s. Purchased Olympic and it worked perfectly. That is the only part of my concrete that looks good. So, it appears that it is possible to develop a formula that works, even with the VOC restrictions. This is not an acceptable product.

Rated 4 out of 5 by Berney12 from Good waterproof coverage I bought this product 2 years ago. I have used it on the wood plank floor to my trailer. It has been great protection for the wood in my trailer.

Rated 1 out of 5 by Treavor from Garbage Don't waste your money. No longer clear. A white pastey mix that plugs the sprayer and is way lighter finish than the same jug I bought 2 years ago. Doesn't apply very easily and will require a second coat. Totally not impressed! What a waste of time and money!!!

Rated 1 out of 5 by TomN from Tackiness I applied this product according to the instructions. my surface was acid stained concrete which is 7 years old. I applied the sealer with a roller and the temperature was approximately 85 degrees. After over 48 hours the sealer was tacky, so much so that you could not walk on the surface. Pressure washing twice with a detergent had a minimum effect. Only after two more cleanings with a degreaser was I able to walk on the surface with still some tacky spots which needed attention. I have used other water based concrete sealers before which have all had very fast drying times and did not remain tacky even after several applications within the same day. Always used Thompson's products in the past and I thought I would revisit the product line. I am sorry I did.

Does Thompson's Water Seal really work?

Thompson's WaterSeal has clearly not been a consumer favorite with deck stains or sealers. Mainly as it does not offer any UV protection and it grays in a few months. The Transparent and Semi-Transparent versions are prone to premature peeling and wearing after about 1 year.

How long does Thompson clear water seal last?

Water Seal can only be used on bare and uncoated brick, stone or concrete. How long will Water Seal last? If applied correctly, Water Seal will last up to 4 years.

Do you need 2 coats of Thompson's Water Seal?

One coat is enough, but if more color is desired, a second coat can be applied within two hours before the first coat has dried. With Thompson's® WaterSeal® Waterproofing Stains, you can clean your tools with soap and water.

Does Thompsons Water Seal penetrate?

Thompson's® WaterSeal® Waterproofers and Exterior Stains penetrate the wood so that even after the beading is gone, the waterproofing protection lasts.
