DYNA® PS-1 Penetrating Sealant is a clear and transparent sealer formulated to protect interlocking pavers, concrete surfaces, cementitious surfaces, their joints, masonry brick, and stucco against stains, dust, dirt, water, acid rain, chemical attack, fungus, salts, UV rays, and efflorescence damage. PS-1 also protects from freeze/thaw damage such as spalling and bubbling rendered by the harshest climates. Treated surfaces develop hydrophobic properties. Non-film forming and will not make surface slippery. Surfaces that are treated with this product absorb significantly less and yet the surface develops no change in moisture vapor transmission.


- Non-film-forming invisible finish
- Protects against spalling, freeze/thaw damage, chemical attack, salt, biological growth, efflorescence, tar, and dirt pickup
- Does not change the appearance of the surface being treated
- Chemically and physically bonds to surface
- Has excellent depth penetration
- UV stable
- Will not peel or yellow
- Vapour permeable


For interior and exterior uses (UV stable), it can be applied on colored porous concrete surfaces such as:
- Interlocking Concrete Pavers
- Stamped Concrete
- Cementitious Surfaces
- Terrazzo Floors
- Masonry Brick
- Stucco
- Grout Joints

Before starting your project, always perform a surface test by applying the product on a small inconspicuous area and let the surface dry for 60 minutes. If you are satisfied with the results, proceed with the work.


1. Remove all stains with the adequate DYNA® Cleaning Solutions.
2. Clean the entire surface area using DYNA® EF Efflorescence Cleaner. This step is necessary in order to remove efflorescence deposits, ground in dirt and color variations. Let dry completely.
3. Let dry completely after cleaning. It is recommended to wait at least 24 hours without dampness before applying the PS-1 Penetrating Sealant. However, if pavers have been exposed to full day sun for 6 hours after cleaning, you can proceed with the application.



When applying PS-1 Penetrating Sealant, the ideal temperature should be between 18°C (65°F) and 25°C (77°F) with no rain in the forecast for the next 12 hours. The surface to be treated should be completely dry, clean and even looking. Morning application is recommended.
(Application under scorching sun is not recommended)


Use a slit foam roller and a metal paint tray. If you wish to use a sprayer to apply the PS-1 Penetrating Sealant, make sure that you back roll the surface immediately with the slit foam roller to even out the


Starting at the highest point of the surface, proceed in small sections of 2 m x 2 m (7 ft x 7 ft) at a time. Using the slit foam roller, roll on one coat of PS-1 Penetrating Sealant followed by an immediate second coat to saturate the surface being treated. Redistribute any puddles or free standing sealant. Proceed to your next area.

Starting at the highest point of the surface, proceed in small sections of 2 m x 2 m (7 ft x 7 ft) at a time. Using the slit foam roller, roll on ONLY ONE generous coat of PS-1 Penetrating Sealant to saturate the surface being treated. Roll out any running sealant to prevent streaking. Proceed to your next area.
When reaching the bottom, clean up all excess sealant at the base to prevent puddling.


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).


Clean all tools with lacquer or paint thinner.
