An industrial-grade, water-based, silane/siloxane engineered to reduce water and moisture intrusion, while protecting concrete or masonry substrates from chlorides and deicing salts. Resists deicing salt/chloride damage, freeze thaw damage, spalling, pitting, cracking Reduces water ingress, moisture intrusion and ASR Excellent water beading effect, excellent penetration, easy application with sprayer, roller or brush, no appearance change – dries clear, Low VOCs Use on driveways, garages, basements, patios, pool decks.

Covers up to 250 sqaure feet per gallon per coat. A new high performance, nanotechnology driven, clear, breathable, deep penetrating, water-based, water and chloride repellent that provides exceptional penetrating power and water repellency.

Siloxa-Tek 8500 is a deep penetrating water repellent that protects against water-soluble deleterious materials, and freeze/thaw cycles. With its long established hydrophobic agents, and through the latest advances in nanotechnology, its intelligent nano particles provide even deeper penetration adding an extra layer of protection.

Once applied the change of the surface tension creates a surface environment that is hydrophobic forming an effective shield that aides in a dramatic reduction of chloride and water absorption. The proprietary nanotechnology offers deeper penetration when compared to traditional silane isomers resulting in an even longer service life that protects the concrete, forming an invisible barrier that leaves the concretes appearance completely natural.

Siloxa-Tek 8505 is an advanced, high performance, industrial strength water based concrete/masonry water and oil repellent solution designed to reduce water and moisture intrusion. This unique formula incorporates leading molecular nanotechnology; putting an end to water, oils, fluids and moisture migration through any porous cementitious substrate.

Siloxa-Tek 8505 is a uniquely transparent, blended formula with added enzymes and surfactants that aide in accelerating a penetrating disbursement. It provides a hydrophobic barrier beneath the surface and seals out moisture while remaining highly vapor permeable and chemically bonding with the substrate.

The treated surfaces will show no change in visual appearance from application and the surface will not chip, flake, delaminate or breakdown with UV light exposure.

Foundation Armor The Armour SX5000 WB is a Department of Transportation approved water-based penetrating water repellent sealer. It penetrates deep into the substrate where it chemically reacts to form a hydrophobic barrier within the pores that reduces surface water absorption by up to 95%.

The Armour SX5000 WB is made from high quality, non-recycled, US manufactured resins. It is designed for unsealed concrete, brick, pavers, natural stone, and porous masonry. It works entirely below the surface, won’t change the look or colour of the substrate, and won’t leave a surface film.

By reducing surface water absorption, cracking, spalling, pitting, mould, mildew, algae, staining, and other damage and deterioration caused by surface water absorption will also be reduced.

Old concrete requires a little extra care when maintaining. Get the job done right with the RadonSeal Plus Clear Protectant Concrete Sealer. Specially concentrated for older, more porous concrete, this material will seal up your old foundations, pads, and heavyweight concrete blocks.

This unique sealer will protect your indoor and outdoor concrete against dusting, cracking, freeze-thaw, deicing chemicals, and efflorescence without changing its appearance. Concentrated for older concrete, RadonSeal Plus is recommended for indoor concrete poured up to 20 years ago or outdoor concrete over 2 years old.

The RadonSeal Plus works by absorbing deep into the concrete and sealing pores and capillaries below the surface. Unlike other sealants, this concrete sealer will not leave behind a glossy coating and won’t cause the surface to become slippery.

This factor makes the concrete sealer a great choice for areas your loved ones frequently walk on every day. Whether you’re renovating your basement or hardening an aging sidewalk, RadonSeal Plus will help you craft a firm foundation the first time around.

Z Aqua-Thane G40 is a water-based, two-component, self-cross-linking polyurethane coating. It exhibits a high-gloss finish and offers superior stain, abrasion, and chemical resistance. The durability makes this sealer ideal for high-traffic areas.

Z Aqua-Thane G40 is safe for indoor or outdoor use. Will provide darkening “wet look”. Amount of darkening will depend on porosity of concrete. Always test on sample to confirm results first. Aqua-Thane G40 vs.

Aqua-Thane M35 – The G40 has a higher gloss finish and will darken or “wet out” the concrete very similar to when water is applied to an unsealed surface. The M35 has a matte/satin finish with very slight darkening on colored concrete.

Provides a glossy, abrasion-resistant finish; Fast-drying; safe for indoor or outdoor use; Excellent chemical resistance and UV resistance Coverage – 50-75 sq. ft. @ 2 coats (one 1. 5 qt. kit) Instructions: Surface Prep: New concrete must be completely cured before applying this sealer.

Any moisture remaining in the concrete can cause adhesion issues. You can check with a moisture meter or by taking several 6×6 inch sheets of clear plastic and thoroughly taping it to the surface completely around the edges.

If after 24 hrs the plastic is dry, it is assumed there are not hydrostatic pressure problems. If acid stains/washes are used, the concrete must be completely neutralized to a pH of 7. A light sanding with 100-200 grit sand paper is recommended on all new hard-troweled concrete to open the surface /promote adhesion.

On burnished, highly-polished or concrete cast against smooth surfaces, additional sanding or acid etching may be required for the best adhesion properties. On textured or stamped concrete, no additional steps are required but in all cases concrete should be clean and 100% free of all dust, debris, or previous coatings.

Mixing: Mix exactly 2 parts of A to 1 part of B. Mix thoroughly with a paint mixing stick and always scrape the sides of your mixing container to ensure a uniform mixture. Mix adequately for 2-3 minutes.

Failure to properly mix components may result in adhesion or hardness issues. Pot life of mixed components is roughly 2-3 hours at 75oF. Application: Concrete surface should be 55oF-85oF. On smaller areas like countertops, a 1/4” nap roller or a micro-fiber applicator pad is recommended.

Product should be applied in a thin, even coating. Do not allow to puddle in low areas. Back-rolling may be necessary to control thickness and guarantee uniformity. Two coats should be applied for sufficient protection.

On rough or more porous concrete additional coats may be needed. Always test with water to confirm concrete is adequately sealed. Re-coat time is 6-12 hours at 75oF and the first coat should be tack free.

If this window is missed, the first coat may have to be lightly sanded with 300 grit paper before applying a second coat.
