Liquid RubberMulti-Purpose Primer - Use on Concrete and Wood, Water-Based Non-Toxic and Fast Drying, Easy to Apply, 1 Quart

Great product must use if you need a good sealant !!!

There seems to be some reviews here for the liquid rubber, when this is supposed to be about the PRIMER you put down before the liquid rubber. This primer is the bonding agent between the liquid rubber and the material you’re applying it to you. Do not skip this step.This review is for the PRIMER: I ordered a gallon (128 ounces), for my project(267 square feet) and I ended up only using about 1/3 of it. This product reminds me of non-fat milk, and is just as runny (but dries clear). This is NOT thick! My project was to refinish a balcony area that already had some sort of product very similar to the liquid rubber. I used a pressure washer one day, then a few days later I used a blower to make sure there wasn’t any dust. I live near the Seattle area and did this project in early September.I used blue painters tape to mask off all surrounding areas. I used a level on its side and a pencil to draw lines on the posts because I wanted to make sure the bottom one inch of the posts were sealed as well (I recommend taking off the blue painters tape within 12 hours of applying the liquid rubber. I took mine off after around 4 hours because it was already dry). I used a regular paint brush to edge in everywhere as thick as I could, which is pretty hard with this being so runny. I applied 2 coats, the second one hour after the first because it dried pretty quick in 70 degree direct sunlight. Then I used a 3/8 nap roller to apply two coats over the rest of the area. This product does not really have an odor. I was able to rinse out the brush for use again. I applied this in the morning because I wanted to apply the liquid rubber the same day. The instructions say to apply the liquid rubber within 24 hours of using the primer, and before the night if dew is forecasted overnight. I would recommend doing this project during the summer time. See my review for the liquid rubber.

Primed my leaking waterfall for a rubberized coating, waterfall doesn’t leak anymore.

Very easy to use and gives great looking results. Surface must be clean but you don't have to use Liquid Rubber's etching solution as there are many etching solutions available that do the same thing for much less. It just has to be a concrete etching solution. It's important to understand that you are applying the material in multiple coats to reach a final thickness. When you determine the square footage then check the specs to see how much material to buy, that amount is what you need to reach the final thickness required. Just put it on until you run out. Put it on as thick as you can with a roller and that's it.You need the weather to cooperate - you cannot have any overnight dew or mist etc. while applying the product and the manufacturer states that you should not apply in direct sun. Almost impossible conditions to meet. I got lucky and had no overnight moisture but had to apply in some direct sun but had no problems. I cannot speak for longevity of this product as I just applied a month ago.

Don't waste tour money on this expensive product. We have put 2 barrels of this product on 2ce and the surface still leaks. Cracks on the surface. Now we are going to have to totally rip up and reseal the deck the deck.

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.

If you are using this product line for your project, you are going to need it, the rubber product needs this for a genuine connection, the advantage to using it, is it does make it water resistant and sealers the wood plug you get better yelled out of the color rubber product.

I don't usually write reviews but I have found this primer very easy to use - very easy to apply, low odor and easy cleanup. I was even more impressed with the level of customer service I received when I had to report that the package had been damaged in shipping. Somewhere along it's journey the "Handle With Care" warning on the packaging had been ignored. I was quickly able to get through to customer service and after confirming the state of my shipment immediately started processing a replacement. I can't say enough good things about this experience and look forward to continuing to use Liquid Rubber products when possible.
