Which concrete sealant and/or stain should be used on a basement floor?
There are a number of products advertised for basement floors. I don't have
any water problems.
2 part EPOXYCoatings
spray/roll on contrete sealers
I have yet to figure out what is best.
That depends on what you are going to do with the basement floor when
it's done. The epoxy coatings are very tough and durable, they are
typically used on applications like garage floors, because they stand
up to oil, gas, tire traffic, etc. the best. And they are the most
Concrete stains vary from products that actually react with the
concrete to ones that are more like paint, ie similar to solid stains
used on exterior siding. They are suited to moderate wear
Concrete sealers are generally clear coats designed to seal the
surface and protect it from weather, keep dust down, allow water to
run off, etc.
And to add to your choices, you can also use a floor/deck paint, which
is what I used on mine. I wanted color and the basement is only used
for storage. For that type of application, either paint or the stain
are easier, cheaper, and work fine.
from my investiagations, all sealers, paints, and such can fill small cracks
and pores in the cement that allow radon to escape. thus, sealing your
basement with any concrete sealer should reduce radon levels. I looked into
some of the radon sealers and they are so expensive. I have yet to see a
major organization endorse any of them. As far as I can tell, they are
simply overpriced concrete sealers.
I eventually want to finish the basement, but that is probably a couple
years away. So, I want a coating that looks nice, makes the area more
livable now, and will reduce humidity entering the house from below.
Sealing a surface before painting is not necessary. Paint will seal
the surface. A sealer is used in place of painting, and the paint
manufacturers will not recommend any paint to be put over a sealer.
Some concrete sealers protect from the surface down, not the ground up
so you need to get the right sealer. UGL makes a product (Concrete
Protector or Masonry Treatment) that does this and you can paint over
it with a latex paint if you like. Plastic sheeting can be used on a
basement floor as a moisture barrier if you plan on installing a vinyl
or wood floor.
I want to eventually finish the basement so I went with UGL's masonry
treatment. I called their 800 number and spoke with one of their
technicians. This product operates as a vapor barrier and prevents moisture
from getting through, which is what you need if you put down carpeting,
wood, or vinyl flooring. The technician said that one coat is enough and
that I can use any latex paint on top of it.
The 2 part epoxies appear to allow vapor to pass through. That's how they
avoid peeling. That's fine if you don't plan on later putting some other
type of flooring in. If you do, you need to install a layer of plastic to
act as a vapor barrier. I do eventually want to apply a 2 part epoxy to my
I applied the masonry treatment to about half of my basement floor over the
weekend. It has a milky white appearance when applied, but dries with a
clear, gloss finish. I used a sprayer to apply it.
A worker at home depot recommended the Jasco product to use as a vapor
barrier on a basement floor. however, when I called jasco they said to NOT
use their product on a basement floor and recommended the UGL masonry
treatment. Jasco said their product would not act as a vapor barrier.
