DYNA® REPEL 4220 is a clear and transparent premium performance penetrating impregnating agent specially formulated to protect porous natural and dimensional stone such as rough, splif-faced, textured, acid-washed, honed, flame finished and sandblasted marble, granite, slate, sandstone, limestone, and quartzite, against stains, dust, dirt, water, acid rain, chemical attack, mildew, fungus, U.V. rays, salt, oil, tar and damage from efflorescence. Surface dirt should be removed using standard maintenance procedures. It allows moisture vapor transmission.
REPEL 4220 also protects from freeze/thaw damage such as spalling, cracking and bubbling rendered  by the harshest climates. It serves to densify the surface of any stone and yet offers no appearance change. REPEL 4220 is not a sealer and as such leaves no surface film to peel or yellow. This product also serves as an anti-graffiti agent. Surfaces treated with this product have a higher co-efficient of friction, therefore polished stone surfaces such as floors become less slippery.


- Provides Invisible Protections
- Treated surfaces develop hydrophobic properties
- Treated surfaces develop oleophobic properties


Can be applied on surfaces such as:
- Rough, split-faced, textured, acid-washed, honed, flame finished and sand blasted marble
- Granite
- Slate
- Sandstone
- Limestone
- Quartzite


1. For interior and exterior use.

1. Do not apply before 10 days following the completion of the work.
2. Certain types of slates and natural stone may darken slightly with the effect that the color will be enhanced, ensure that you always test first to determine if this is what you desire.
3. Do not apply below 0 °C ( 32 °F ) or above 40 °C ( 104 °F ).
