DYNA® PW-1 Penetrating Sealant is a ready-to-use, water-based silane / siloxane water repellent for concrete, natural and dimensional stone, masonry and stucco surfaces. PW-1 permits the surface being treated to breathe. It helps prevent masonry from cracking, spalling, staining and other damage related to water intrusion. It has low odor, is alkaline stable and is ready to use. Use on horizontal surfaces such as driveways, sidewalks, tile, brick, sandstone and pavers. Provides excellent protection for retaining walls, bridge pilings and other vertical areas exposed to de-icing salts.


- Excellent for exterior and interior
- For residential and commercial installations
- Penetrates deeply for long-lasting protection on vertical or horizontal surfaces
- Treated surfaces “breathe” – moisture will dissipate
- Water-based formula minimizes explosion and fire hazards compared to solvent-based water repellents
- Low odor for safer application in occupied buildings
- Alkaline stable – suitable for new “green” concrete, 14–28 days old
- Ready-to-use. No on-site dilution required
- Chemically bonds with the substrate which produces a durable hydrophobic treatment
- Effective protection against de-icing salts and salt air
- Easy soap-and-water cleanup from window glass, window frames and equipment

1. Protect people, vehicles, property, plants, windows and all surfaces not to be treated with this product, from splash, residue, fumes and wind drift. Protect and/or divert pedestrian foot and auto traffic.
2. All substrates should be structurally sound, stable, dry, clean and free of any substances that may reduce or prevent proper application of this product. Thoroughly clean the surface using the appropriate DYNA® brand of cleaner. Clean newly constructed and repointed surfaces before application. DYNA® PW-1 Penetrating Sealant won’t impair adhesion of most sealing and caulking compounds.
Always test for compatibility.
3. Though PW-1 may be applied to slightly damp surfaces, best performance is achieved on clean, visibly dry and absorbent surfaces. Excessive moisture inhibits penetration, reducing the service life and performance of the treatment.


No mixing requires. The product is ready for use.


Read the Safety Data Sheet (SDS) before use.
ALWAYS TEST a small area of each surface to confirm suitability, coverage rates and desired
results before starting overall application. Best results are achieved with a low-pressure (<50 psi) sprayer with a fan-type spray tip and adjustable pressure to avoid atomization of the material. For small scale application, or when spray application is not appropriate, brushes or roller may be used.
For best results, apply “wet-on-wet” to a visibly dry and absorbent surface.

Spray from the bottom up, creating a 4–8 inch (15–20 cm) rundown below the spray contact point. Let the first application penetrate for 5–10 minutes. Re-saturate. Less will be consumed and greater coverage will be achieved in the second application.

Recommended for small scale application or when spray application is not appropriate.

Saturate in a single application. Use enough to keep the surface wet for 5–10 minutes. Broom out puddles until they soak in.

Apply a single coat. Use enough to completely wet the surface without creating drips, puddles or rundown. Do not over apply. Apply a second coat.


1. For newly installed surfaces, wait at least 60 days before using this product.
2. Do not apply if surface is damp or dirty.
3. Do not apply if weather is uncertain.
4. Do not apply in extreme heat. (Mid-day sun).


Wash your tools immediately after application with water. Clean your hands and tools with soap water.
