Penetrating Water Repellent Sealer
The product that protects the finish — a barrier against water absorption, efflorescence, UV light fade and freeze/thaw damage.
A waterborne, non-toxic, low-odor, low-VOC, non-flammable silane / siloxane water repellent.
It penetrates the Arcusstone coating and chemically reacts to form a powerful barrier against water absorption, efflorescence formation, UV light fade and freeze/thaw damage.
Application will not alter the color or texture of the Arcusstone coating.

Where it goes
- Uses
- A penetrating water-repellent barrier over most applications of Stonecoat and Arcus Plaster, and other cementitious materials.
- Required seal
- Arcus Plaster, Marblecoat, Lime Plaster Fine and Lime Plaster Medium must each be sealed with it.
- On every finish
- Arcus Plaster, Marblecoat and both Lime Plasters are always sealed; Stonecoat as set out below.
- Stonecoat
- Required on exteriors in extreme climates — higher freeze/thaw cycles, higher and more constant UV exposure, higher altitudes, or higher humidity and subtropical or tropical locations — and in wet locations, countertops and all exterior horizontal applications.
- Coated shapes
- Manufactured EPS shapes are sealed at the manufacturing facility before shipping.
Where it does not go
- Not formulated for substrates with hydrostatic pressure, such as retaining walls.
- Not intended to seal cracks.
- Not for pool surrounds, submersed applications such as fountains, or any area subject to water immersion or caustic chemicals.
- Not appropriate for polished stone — it must penetrate and react with the surface to be effective.
- Do not apply to hot, wet, frozen or thawing substrates.

Technical details
For specifiers and applicators. The product data sheet above carries all of it.
Applying it
- Method
- A low-pressure, high-volume pump sprayer at 20 – 30 psi. Airless sprayers are not acceptable.
- Mixing
- Stir well before application, by hand only. Do not dilute or thin.
- Before
- New Arcusstone coating cures a minimum of 48 hours before it is treated.
- Temperature
- Surface and air between 45°F (7°C) and 90°F (32°C).
- Surface
- Sound, dry, and free of cracks, dirt, efflorescence or other contaminants. Protect plants, shrubs, glass and other surfaces from overspray; remove overspray at once with a mild soap-and-water solution, without letting it touch the surface being treated.
- Coats
- Two applications, wet on wet, are required for maximum penetration, protection and warranty.
- Direction
- Saturate the surface working from the bottom of the wall upward; on horizontal surfaces, let it dwell a few minutes and blot off any excess that has pooled.
- Protection
- Keep treated surfaces from rain and direct water splash, including landscape sprinklers, for at least 24 hours.
- Cure
- Effectiveness relates to cure time, which lengthens below 65°F (18°C); allow 14 days before evaluating performance.
- Clean-up
- Immediately, with water and mild detergent, rinsing with clean water; once dry, mechanical means may be needed.
Storage and shelf life
- Store in a cool place out of direct sunlight, on pallets under cover, not exposed to weather, no more than 2 pallets high.
- Keep from freezing. If frozen or partially frozen, discard.
- Shelf life: 1 year in unopened original pails, or 6 months once opened and properly resealed.
