Beautiful textures and colors. Many choices for sealer finish gloss level - from none to high gloss
Your Choices for Sealing
This surface is usually low absorption. Water base penetrating sealers have a difficult time penetrating down. Solvent base penetrating sealers may require being sprayed to achieve a smooth finish.
Our suggestions to test are:- Penetrating petroleum solvent formulas with acrylic solids. These can be sprayed to finish nicely, but solids level might need to be adjusted if manufacturer allows dilution.
- Water based film forming that can flow out and self-level.

Some questions you may not be thinking to ask right now that could become important:
. Was it sealed in the past? Does that matter?
. Will a new sealer be compatible with whatever was used before?
. What sealer will give the visual results you want?
. Will you also be able to have a sealer solve problem(s)? ( Answer: yes. Just know which to pick.)

How to select a sealer
A sealer can do far more than just bead water and look pretty! To see what that is click here.
Important: If your project has had any sealer applied in the past, it must be evaluated differently. To see why, Click here!
Sealer "solids" levels?
A porous surface will require more gallons (more money) of a lower solids sealer than using a higher solids level sealer. That, plus different surfaces have different requirements. It is only a matter of which is best for your needs.
The more porous the surface, the more solids will be required to achieve the desired effects of gloss, strengthening, stopping efflorescence, etc.
The more porous the surface, generally the greater the need for the sealer to create a stronger surface.
An old sealer below the surface, even after stripping, will lower the absorption and porosity to some degree. Sometimes it is uneven below the surface and can create an uneven coloring effect with a color enhancing sealer applied later. Another reason to test first.
Do not believe yet that you have the type of surfacing you were told:
Colors fading?
Renew a glossy finish
Re: "penetrating sealers": do not apply thin layer upon thin layer. Apply a sufficient quantity to insure below surface penetration & bonding. A layer of sealer on top of another layer of sealer can result in poor bonding between layers and that can cause separation peeling that looks grayish.
Concerned about Doing It Yourself or what your contractor says?
If you are concerned about doing it yourself - consider that the satisfaction of a project is directly related to YOUR knowledge of what needs to be done and how. Who actually does the work is less important.
