One common question that both DIYer’s and contractors alike ask is:
“How much sealer should I apply?”
The porosity of your pavers is critical to the answer. Think of this as the
“sponge factor.” The more porous the paver, the more liquid or sealer
it will absorb. The first step in figuring out how much sealer you need is
determining the porosity of the paver from the start of your project.
Generally, the densest surfaces don’t accept much liquid. On the other
hand, very porous surfaces will quickly soak up water. Is the surface you
want to seal DENSE or POROUS?
Try to drip a few water droplets on the surface.
• If your surface is more dense (water droplets are absorbed for longer than
5 seconds), you will be at the higher end of the coverage rate.
• If your surface is more porous (water droplets are absorbed within seconds),
you will be at the lower end of the coverage rate.
Denser surfaces (previously sealed surfaces) may only need one coat of
sealer. If the water doesn’t absorb, then more sealer won’t soak in. More
is not better. We always recommend performing a test area with the
selected sealer to know how much is needed on your project, and that
you’re happy with your result.
