Could this product be used instead of paint on a concrete basement floor to keep away dust? How many liters for an 1879 sq ft home?
Yes it can be used on basement floor depending on concrete, porous yes smooth may make it slippery. and you would need 8 cans with a bit left over.

Hello, can this product be used inside of a small greenhouse (4x10) to help seal wall and roof trusses? If not, is there another recommended product?
hello I have a garden water fountain made of some sort of cement and has a beige paint, unfortunately during the summer it gets very dirty with algea and hard to clean, can i use your product to coat it so the algue will not stick directly on the surface?
It's good for the house stone floors? Hot location.
Est-ce que l'on peut-être poser sur de la pierre?
When dried the product is matte or wet look?
I have bought composite decking boards and railings but I heard that they discolour with time does your water seal can be used on this material and does it offer a UV protection
For this can (3.78l) what square footage can be covered roughly by spray application thanks

Use with confidence
We have a 14 year old PT deck, which was badly weathered and had significant organic matter covering most of the surface. After pressure washing, I applied one coat of Thompson’s Multi-Surface Water proofer, and our deck now looks brand new.

Thomsons multi purpose water sealant
About a month ago, I applied clear multi purpose wood sealant on my wooden fence and rail Within a month of application wood looked beaten and faded/ greyish. Any suggestions on what I should do and when? The wood I used to make the fence and rail is Basra Locus. This was done in March 2024 .Attractive wood grains. I live in the Caribbean temperature very hot. I am very disappointed

Garbage!
Long couple days pressure washing our concrete driveway which made it look incredible only to use this crappy sealer that made it look horrible! Wish I would have seen these reviews first. So now we are stuck with this stained driveway and to top it off it rained today and it doesn’t even bead water. It is a complete garbage product and I will never purchase it again, lesson learned!

Perfect for backyard deck and the concrete walkway
I use this for my backyard deck and the concrete walkway. This works perfect for my needs as I have two different surfaces to process.

Don't use it on concrete pavers
I wish that I had read these reviews before buying this product. It has destroyed my patio. I've spent the last 2 weekends trying to clean it with mineral spirits and a pressure washer, per their suggestion, and it is still a mess.

Fantastic product
I purchased product a few weeks ago to seal a picnic table. Thompson is a product I’ve relied on to protect my outside items

This is absolutely the worst product on the market
This is absolutely the worst product on the market for concrete! This is the first time I have used a Thompson's product and will never use any of their products again, for any reason. I finished power washing our front entry sidewalk and a large portion of our driveway, to prepare for sealing. I applied the remainder of a GOOD sealer I had on hand to the majority of the front entry sidewalk. The building supply company where I bought the GOOD sealer was not open, so I decided to try Thompson's Multi-Surface, because it states on the can that it dries clear.
This product DOES NOT dry clear and has ruined our driveway! I should have read all of the complaints and reviewed the pictures before buying. With so many complaints and customer losses of hundreds to thousands of dollars, I'm surprised that a class action lawsuit has not been filed against Thompson"s. Something worth considering. I would like a refund, so I can then take that money to buy something to remove the horrible Thompson's product from my driveway.
