MB Stone Care MB-24 Barrier Impregnating Sealer

MB-24 Barrier Impregnating Sealer for Stone, Tile & Grout

MB-24 “Barrier” is a water-based Professional grade fluorochemical impregnating sealer that is extremely user friendly for homeowner and pro alike. Easy to apply to small or large areas; floors, counter-tops and any surface that requires sealing.

MB-24 provides a durable, non-film forming, transparent, protective barrier against oil and water on porous surfaces such as marble , limestone, travertine, granite, slate, unglazed tile, grout, terracotta, concrete and brick. Barrier provides excellent oil and water repellency, stain resistance, and easy stain cleanup.

A formidable water based penetrating sealer for all porous natural stone, concrete, terrazzo, terracotta, saltillo, slate and grout. MB-24 Barrier will provide excellent hydrophobic and oleophobic protection, stain resistance and easier stain cleanup.

Instructions for Use MB-24 Impregnating Sealer

For Countertops

1. Check surface for porosity(see test instructions in flooring application).
2. Mask off and protect any surfaces not intended to be treated.
3. Liberally apply an even coat on surface being treated. Seal surface in manageable sections so there is less possibility of leaving any residues behind. On counter tops we like to work a 6-7 foot linear section at a time.
4. Allow sealer to penetrate the surface for 5–15 minutes; denser material may require more time for sealer to penetrate. During this time make sure the surface area you are working on stays wet by moving product around to dry areas if that happens.
5. Thoroughly wipe the entire surface with a clean dry cloth to completely remove all excess sealer from surface.
6. DO NOT ALLOW EXCESS SEALER TO DRY ON THE SURFACE. Tip-Good quality paper towels work best on counter tops for removing sealer residue.
7. Apply second coat as needed for porous ,absorbent surfaces 1 hour after first coat, following directions in steps 3 through 6.
8. If sealer was not completely wiped off and a residue appears, reapply a thin coat to that area, let sit for a minute or two and then using paper towels buff off all residue. Wipe again thoroughly with clean, dry towels. Surface may be used in 6–8 hours once all residues if any have been removed.
9. A full cure is achieved after 24–72 hours. Do the water test after 24 hours and see if the surface exhibits any porosity-If it does you can repeat the process until no more absorption occurs.
10. Clean tools used during application with water.

For Floors

Test surface for porosity. Place a small amount of water and allow to sit on surface for 10-15 minutes. Then wipe away water and see if a darker mark is left. This will indicate the surface is porous and requires sealing. You can gauge how porous by the amount of water taken in and how long it takes to dry out.

1. Cover and or protect any surfaces that is not meant to be treated.
2. Liberally apply an even coat with a paint pad, paintbrush, paint roller or finishing mop. Seal surface in manageable sections so there is less possibility of leaving any residues behind. We like to work 50 sq. ft. to 100 sq. ft. areas at a time. Make sure when you apply the next area you overlap the previous one.
3. Allow sealer to penetrate the surface for 5–15 minutes; denser material may require more time for sealer to penetrate. During this time, make sure the surface area you are working in stays wet by moving product around to dry areas if that happens.
4. Thoroughly wipe the entire surface with a clean dry cloth to completely remove all excess sealer from the surface. DO NOT ALLOW EXCESS SEALER TO DRY ON THE SURFACE. Tip-Use paper towels, rags and or a buffing machine with carpet bonnets to remove the excess.
5. A second coat may be needed for porous, absorbent surfaces and should be applied one hour after initial application as directed in steps 2 through 4.
6. If sealer was not completely wiped off and a residue appears, wipe entire surface with a towel dampened with sealer. Use a white nylon pad to loosen residue and follow with a clean, white absorbent towel to remove.
7. Do not walk on surface for at least 4–6 hours. Full cure is achieved in 24–72 hours.

What Is The Difference Between Topical And Impregnating Sealers?

Topical and impregnating sealers are both used to protect surfaces, particularly in flooring and masonry, but they serve different purposes and have distinct characteristics.

Topical Sealers

• Application: These sealers are applied on the surface and create a protective layer that sits on top of the material.
• Function: They provide a barrier against stains, moisture, and wear, enhancing the surface’s appearance by adding gloss or color.
• Common Uses: Often used on concrete, stone, and tile surfaces where a shiny finish is desired.
• Maintenance: Requires periodic reapplication as they can wear down over time, especially in high-traffic areas.

Impregnating Sealers

• Application: These sealers penetrate into the pores of the material, providing protection from within.
• Function: They are designed to repel water and oil, reducing the risk of stains without altering the surface appearance significantly.
• Common Uses: Commonly used on porous materials like natural stone, brick, and grout.
• Maintenance: Generally longer-lasting than topical sealers and may not require frequent reapplication, although they do need to be reapplied eventually.
