Liquid Rubber Multipurpose Primer - Use on Concrete and Wood, Water-Based Non-Toxic and Fast Drying, Easy to Apply, 1 Gallon

This is the most unique primer I've ever used as it is water thin and goes on like a poly as opposed to thick like paint. Have no idea it's effectiveness, but grabbed the wood well. We will see as time passes.

Excellent primer! Dries kinda clear so you’re not sure it’s going to work. Used along with their deck paint to redo the front porch on my 100 year old house. Stripped old paint best I could and sanded. Applied two coats of this then 4 coats of the final paint. Been one year and looks as good as day one. Pricey but you get what you pay for. If you have a demanding application consider using this primer.

Stuff goes on great and works well. Awesome customer service

This primer is thin like water and is clear so it leaves a shine on the deck. Should soak into the wood better.

I used this product when rebuilding the roof on my 1992 Coleman pop-up camper. I used the product to prime and seal the exterior wood of the camper roof. I researched this product before using it. I called liquid rubber and they very nicely answered my questions. They explained that this primer product is much like an epoxy sealer primer. It is very user-friendly and you do not have to mix two components. It really binds to the wood and makes the final topcoat of the liquid rubber RV roof coating really grab. You should not expect this primer to really color, or change the appearance of the wood, a whole lot. It is merely a bonding agent to be used between the wooden substrate and the topcoat. It goes on kind of milky/watery, and then dries clear over the wood.

This shouldn't even be sold.It does not work like they said.All the other products did, but not this stuff. No matter what you do this stuff beads up, it doesn't do much of anything.It's a definite waste of money.

I bought this primer and also the sealer I looked for quite some time before I made a purchase and I absolutely need the right choice this stuff is great not only did I see all my RV just as with precaution routine maintenance I also sealed my dad's pole building where the screws go in and also our pole building where the screws go in he did have a leak in his we did have a leaking ours and there are no more leaks it is worth every penny use this primer and the sealer and it comes out beautiful very satisfied

Excellent for step one concrete ponds.
