Professional Grade

Water-Based Siliconate Water Repellent Sealer for Unsealed Concrete, Brick, Pavers, Natural Stone, and Masonry

Description

Siliconate Water Repellent and Salt Guard for White Concrete

The Armor SC25 is a high solids, water-based siliconate water repellent sealer that penetrates deep into the concrete surface where it fuses with the substrate to form a cross-linked hydrophobic barrier within the pores. Surfaces sealed with the Armor SC25 are more resistant to the damaging effects of water absorption and salt damage. It is a fantastic sealer for unsealed white and light concrete surfaces.

Benefits:

  • Can be used on new, uncured concrete
  • Won’t change the look, color, or texture of the surface
  • Works entirely below the surface and won’t leave a surface film
  • Reduces damage and deterioration caused by water absorption
  • Reduces damage and deterioration caused by snow and ice
  • Reduces the growth of mold, mildew, and algae

Application Instructions

Surface Preparation:

The Armor SC25 should be applied to a completely clean and dry surface. If the surface was cleaned with water or pressure washed prior to application, allow the surface to dry for at least 24 hours before sealing. While the surface may appear dry and feel dry to touch, water below the surface trapped in the pores can cause the same issues. While pressure washing the surface is typically sufficient, spot treatment may be necessary for deep or older stains. If the surface is smooth troweled, or does not easily accept water, acid etching may be required prior to applying sealer. It is always suggested to apply the Armor SC25 to a test area to verify absorption, coverage, compatibility, and project suitability.

The Armor SC25 is designed specifically for unsealed white or light concrete surfaces. Do not apply this product over a surface recently sealed with a water repellent sealer, or previously sealed with a film-forming sealer or coating. Do not apply this product to medium to dark concrete, or any other type of masonry.

Application:

A commercial pump sprayer is recommend to achieve best coverage and results. Be sure the psi is no greater than 20. Use a .3-.5 GPM adjustable cone tip.

Apply one coat of Armor SC25, ensuring the entire surface is evenly saturated. Broom out puddles until surface is penetrated. Do not attempt to apply a second coat.

Time of Day

The temperature of the air and surface must be 55-85 degrees F during application. If freezing conditions exist prior to application, it is highly recommended that the substrate be allowed to fully thaw. Should this recommendation not be followed, the product may not yield adequate protective properties.

Once applied, the surface should be kept dry for at least 24 hours.

Clean-Up

Use warm water and soap. Dispose of containers in accordance with local and federal regulations.

Product Removal

Armor SC25 penetrates deep into to the surface. Removal is not recommended.

For in-depth up-to-date application instructions, please refer to the Technical Data Sheet and Safety Data Sheet for this product. Documents, videos, and customer photos can be found HERE.

Coverage

Porous Surfaces: Up to 175 square feet per gallon in one coat.
Smooth Surfaces (once properly prepped): Up to 200-225 square feet per gallon in one coat.

Coverage will vary depending on porosity, surface condition, application method, and the amount of material applied by the applicator. The above coverage rates are estimates and will vary. Two coats are suggested for even coverage and appearance.

Uses

The Armor SC25 is designed specifically to be used on unsealed white or very light concrete It can’t be applied to surfaces recently applied with a water repellent sealer, or surfaces previously sealed with a film-forming sealer or coating. It can’t be applied to medium to dark gray concrete, colored concrete, brick, exposed aggregate concrete, slate, flagstone, masonry, or anything other than white or very light concrete. Applying the Armor SC25 outside of the suggested application will result in the formation of white crystals on the surface that can only be removed through mechanical grinding.

If you are looking for a water repellent sealer for unsealed medium gray concrete, red clay brick, natural stone, or other masonry, consider instead the Armor SX5000 WB.

Fast delivery great repellant and sealer!

I was scrambling to find a deep penetrating concrete sealer for my garage threshold repair and your Armor SX5000 Silane Siloxane sealer was perfect. It penetrated and dried to a hard finish over 24 hours as described. I have safely driven over it since.

Great Sealer and Easy To Apply

I ordered a 5-gallon pail a month ago and cleaned my 2 year old 555 square foot drive way by scrubbing with TSP and then giving it a light power wash. After making sure it was dry and there was no rain in the forecast for 24 hours I applied the solution with a 3 gallon low pressure sprayer. It took me about 45 minutes and I used the entire 5-gallon pail (expected coverage for my somewhat porous driveway). I did this at 9am in the morning to avoid direct sunlight but the driveway was dry in 65-70 minutes. We got 1/2 of rain last night and the Armour SC25 did it's job well - water beaded up and not soaking in to the concrete.I love it and it's well worth the price to protect my $5000 driveway.Michigan has a heavy freeze/thaw cycle in the spring and over the years that process caused my old drive to crack heave chip and become unusable.It does what the makers say it will do. I'm going to get some more in a month and do my garage floor sidewalks and concrete porches.
