Description
Ultra Seal Penetrating Natural Stone Sealer is a breathable, water-based penetrating treatment for natural stone, concrete, brick, block, foundations, and aggregate surfaces where the original appearance should remain visible.
Product performance overview
Penetrating protection is chosen when the goal is to reduce water and contaminant absorption without creating a glossy surface film. Porosity, absorption rate, moisture, prior treatments, and the material itself determine whether the product can penetrate and perform as intended.
What this product is designed to deliver
- Penetrating and breathable protection
- Helps reduce water absorption, salt infiltration, and freeze-thaw stress
- Colorless, non-yellowing natural appearance
- May be applied to appropriately damp surfaces when the product directions allow it
Where it performs best
Natural-looking protection for stone, concrete, brick, walls, foundations, and other porous mineral surfaces.
Measure before ordering
Coverage varies with porosity and absorption. Use the Coverage Calculator and confirm the substrate can accept a penetrating treatment.
Open the Coverage CalculatorBuild the application around product requirements
Identify the substrate, remove soil and residue, allow the surface to reach the required moisture condition, verify absorption, calculate material from tested coverage, and remove excess product exactly as directed.
Application overview
- Clean the substrate and remove oil, organic growth, efflorescence, and loose material.
- Confirm the surface is compatible and test for absorption.
- Apply evenly without leaving puddles or unabsorbed residue.
- Allow the treatment to cure according to the product directions before evaluating water repellency.
Technical noteSurface compatibility, weather, moisture, dilution, mixing, dwell time, and cure requirements vary by product. Read the current label and SDS, test a small area, and follow the product-specific technical directions before full application.
Frequently asked questions
Will this sealer change the color?
It is designed to preserve a natural appearance rather than create a glossy wet look. Always test first because substrates vary.
Can it be used on natural stone?
Yes, the product is intended for properly prepared, unsealed natural stone and other porous mineral surfaces listed in the product information.
Does penetrating sealer form a film?
This system is designed to penetrate and remain breathable rather than create a heavy surface film.
Confirm the surface, finish, coverage, and application conditions before checkout.
