Sealer for Existing Concrete Sidewalks/Pavements

Sealer for Existing Concrete Sidewalks/Pavements

Sealer for Existing Concrete Sidewalks/Pavements

I propose to clean the surface of some concrete sidewalks/pavements using a Torbo Wet Sand Blasting System. The existing surface is dirty due to oil stains, bubble gum, ferrous oxide stains etc.
What type of sealer product can I use to seal the concrete surface when cleaned? The sealer should be colorless and the surface finish shall not be slippery for obvious reasons. The sealer will be exposed to the very agressive climate in the Middle East i.e. high humidity and temperature with high uV exposure.
I would appreciate any ideas you guys might have.

There is a product called AST D45 which is used for sealing marble tiles and garage driveways etc. it is a waterbased PU acrylic.  it is very long lasting in UV climate and very hard wearing. surface grip with any coating product will depend on existing prifile, but this system is only 30 Microns dry and soaks into poruos surfaces.
Send me you postal address and I will send you some data I hapen to be going out to UAE on 17th from Uk, so will post locally.

There are many industrial grade penetrating sealer products that can work well for you.  You'd want something with little or no film build and pentrating epoxies are my favourite.  The acrylic and polyurethane types tend to be a little less durable than 100% solids epoxy sealers, but this will be something it is difficult to get consensus on.
All sealers tend to darken the appearance slightly, which is good for telling where the sealer has been applied.
Happy sealing!

If UV is an issue then I wouldn't use epoxy... UV can break down epoxy material.
