Is Thompson's water seal a latex product ?

Asked by: Ed
No, It's properties act similar to paint in protection but is formulated to enter into the pores of wood and concrete to create a barrier against water.

5 gal. Clear Multi-Surface Waterproofer is rated 3.1 out of 5 by 140.
Rated 1 out of 5 by from VERY disappointed We had recently built a new deck after having our pool put in. We purchased 2 of the 5 gallons of Thampson's WaterSeal clear multi-surface waterproofer. Less than 4 months after following the directions & applying two coats as directed as well..... the deck looks awful. It looks old & it has a lot of mold in several places. Each week it seems to have so much more. This is the first time we have ever used this produce and it's the first time we have ever had one of our decks to look this bad. Honestly, our new deck looks so much older than our 15 year old deck. I just hope our deck can get back half of it's original beauty...... I can't even explain how heartbreaking & disappointed it is to have spent the money & time on our deck & it look the way it does. Just want others to know before making the same mistake.

Due to lack of maintence in past years, it is beat up and in poor condition. In spite of this, the rejuvenating effect is instant and obvious after appling Thompson's clear multi-surface warerproofeer.

Rated 5 out of 5 by from Excellant Protection I have used Thompson's WaterSeal for many years to protect the masonry work on my property. During winter months, moisture can penetrate masonry and freeze. The freezing can crack and split the outside finish as it expands. Applying Thompson's WaterSeal before the anticipated first freeze of the season prevents damage due to freezing. It also protects staining due to water runoff during rains and dew. Thompson's WaterSeal is the best sealer I have found that works for a full season with guaranteed results. Due to the uneven rough surface I am protecting, I apply the sealer with an industrial sprayer. The sealer dries clear and does not change the appearance of the masonry.

Rated 5 out of 5 by from Shield against elements Thompson's has been around for years. I have used it on all of my outside deck and concrete projects. It is easy to apply with a paint roller, brush, or sprayer. For best results on established decking or concrete I recommend pressure washing to clean out the dirty pores and spots of your project. This opens up the pores to receive Thompson's for a better and longer lasting seal against weather elements. Just follow the directions on its application because you don't want to use too much where it puddles because it starts to repel itself when it starts to cure.

Actually It is lumpy, I still have half and I can bring it back to show you I am disappointed. In it maybe a bad batch or sat to long but even after shaking it and stirring it is lumpy.
