I have a some questions concerning your GBS Penetrating concrete sealer. I want to use it on a basement floor that has some areas that were ground down to make it level. It also has some areas the were patched with a concrete patch. Do I need to etch the concrete where it was ground and patched? Also how long can it be stored? I want to order it now when it will not get cold during shipping, but I plan to apply it on my basement floor later this winter. I can store it so it will not get cold and the basement room will be heated as well. Thanks , Julie SAMPLE - Green Building Supply, Penetrating Concrete Sealer Concrete & Masonry Sealers

This product has a 2 year shelf life.Provided the concrete has already been patched and has no other sealers on it then you should be good to go. You do NOT want to do any patching after the concrete sealer has been applied as the sealer can influence patching ability to stick.The main requirement is that the concrete is unsealed, clean, dry, neutral pH and porous. You can test the porosity yourself by sprinkling water on top of your concrete. Does the water soak in? Or does it bead on the surface? If it beads you will need an etcher for those surfaces. We sell one of those. Green Building Supply MicroEtch. We've also got samples if you want to test for a good bond as well.
