Water based penetrating sealer for natural stones.

MB-24 Barrier is a formidable water based penetrating stone care granite sealer for all porous natural stone, concrete, terrazzo, terra cotta, saltillo, slate, and grout. MB-24 Barrier will provide excellent hydrophobic and oleophobic protection, stain resistance, and easier stain clean up. Safe to use on food prep surfaces.

Directions for use:

Read the safety data sheet completely before use.

Make sure surface is dry and free from soils, waxes, sealers, and/or coatings.

Liberally apply an even coat on the surface being treated using a lambswool applicator, paint brush, low pressure sprayer, or spray bottle.

Allow the sealer to soak into the stone's surface for up to 30 minutes, while moving the sealer around to avoid drying on the surface during dwell time. Stone surfaces will have different rates of porosity. If the sealer absorbs into the surface in under 10 minutes, multiple applications will be needed. Repeat the process until the sealer stays wet on the surface for more than 15 minutes. 
DO NOT ALLOW EXCESS SEALER TO DRY ON THE SURFACE. After the sealer has remained wet on the surface for approximately 20 minutes, you must remove all sealer and residue from the surface with a dry cloth or towel.

Should any residue be left or dried on the surface, you may be able to remove it by applying a light coat of sealer to the affected area and buff it off using a clean cloth. 

We recommend that you complete the first application of the entire surface in manageable sections, so the sealer does not dry on the surface. For countertops, we recommend working 7 to 8 linear foot sections. For floors, 50 to 100 square foot sections. Complete one section and then overlap the following section using steps 3-5 until the entire surface has been sealed. At this point, all excess sealer and residue should have been removed from the first application. Perform a second application, if needed. 

All stone surfaces are different, maximum stain protection is after sealer has fully cured. This takes 24 to 36 hours. 

When properly applied and cared for, MB-24 Barrier will protect for 3 to 5 years.

Coverage: 150 sq ft to 250 sq ft per quart.
