Siloxa-Tek 8500 Ready to Use – 1 Gallon Penetrating Concrete Sealer, Water and Salt Repellent. Clear, Water-Based DOT Approved Silane/Siloxane for Concrete, Brick, Masonry & Pavers
- Siloxa-Tek 8500 is a water-based, silane/siloxane engineered to reduce water and moisture intrusion. Will not change the aesthetics, leaving your concrete, pavers, brick and stone with its original natural appearance. This low VOC formula is 100% breathable and non film forming (meaning it will never peel flake or delaminate).
- Siloxa-Tek 8500 is D.O.T (Department of Transportation) approved and resists surface damage caused by chlorides and deicing salts. It mitigates cracking, spalling and pitting and protects against surface degradation from freeze thaw damage.
- Siloxa-Tek 8500 is a supercharged penetrating sealer with 6x higher actives than any other water based concrete sealer on the market for long lasting protection that actually last. Resists wind driven rain.
- Siloxa-Tek 8500 is a commercial grade, impregnating sealer for commercial and residential applications. Its high actives formula is UV stable and will not break down from direct sunlight. There is no change to the surface profile ensuring a non slick surface. Siloxa-Tek 8500 is the next generation of impregnating sealers with smaller active particles for even deeper penetration for unrivaled protection.
- Excellent water beading effect, easy application with sprayer, roller or brush. Use on driveways, garages, basements, patios, pool decks. Covers up to 250 square feet per gallon per coat. If installed by certified applicator vertical applications can last up to 10 years before reapplication is required.
Product Details:
- Excellent waterproofing – Penetrates deep within the concrete chemically reacting within the pores and capillaries creating a long-lasting hydrophobic surface that beads water
- 100% breathable – Non-film forming. Allows moisture within the concrete to escape without adverse effects to the sealer. Does not trap moisture
- Provides ease of maintenance
- Protects against chloride ion penetration – Forms an effective chloride screen dramatically reducing chloride ion ingress preventing deicing salt / chloride damage
- Reduces moisture intrusion – Resists wind-driven rain, prevents freeze-thaw damage, spalling, pitting and cracking.
- Resists organic growth – Resists lichen, and efflorescence
- Department of Transportation approved – Meets and exceeds DOT specifications
- Improves durability – Prevents capillary uptake of water and the aggressive substances dissolved in it
- Resists freeze thaw and thermal cycling damage
- Natural flat finish – Does not change surface appearance, UV stable will not breakdown with light exposure
- Can be applied to cured, honed and polished concrete – Ideal for horizontal surfaces exposed to pedestrian and vehicle traffic, compatible with silicate densifiers
- Water based – Low VOC’s













Jyotishka Ray –
Product works great. Very easy to apply and can’t even tell it’s on there until it gets wet and beads up. Very happy with purchase.
