Micro-Seal Silane Siloxane Water Repellent
Penetrating Silane/Siloxane Technology
Ensures your project is protected from water intrusion and helps prevent efflorescence, lime, spalling, freeze/thaw damage, stains, mold, mildew, and UV damage.
Preserves the look of the surface with a clear, natural finish and does not darken or add gloss to the surface.
Safe to Use
Can be applied anywhere in North America because it contains zero VOC’s, no carcinogens, no odor and can be applied on interior or exterior, vertical or horizontal surfaces.
Easy to Apply
Quickly apply with an airless sprayer in a flood coat (See TDS below for details).
Protects surfaces up to 10 years.
Micro-Seal Silane Siloxane Water Repellent
Protect, restore and extend the life of your project with Micro-Seal® Clear Finish Silane / Siloxane Waterproof Coating. It is a clear penetrating water repellent that is non-yellowing, low odor, zero VOC, and non-toxic. Formulated to not be affected by weathering, salt, dirt, freezing temperatures, UV light, and wind-driven rain, among many other damaging elements. Micro-Seal dries down to a clear, natural finish that does not change the surface texture or color. Ideal for use on uncoated/unpainted, vertical/horizontal, interior/exterior surfaces such as: concrete, brick, pavers, wood, porous natural and artificial stone, masonry, unglazed/unpainted porous tile, and color integrated or unpainted stucco.

Best Tools for Application
A foam brush is recommended to soak in and saturate your substrate.
Use a small hand pump sprayer.
Use an airless sprayer with a spray tip size between .035mm to .051mm.
Application Best Practices
1) Step One: Prepare the surface and confirm surface moisture is less than 25%. Remove dirt, grime, efflorescence, lime run, construction debris, form oils and release agents, chalked materials, loose and peeling paint, mold, mildew, etc. All cracks should be pointed or caulked.
2) Step Two: Perform a test application to confirm fit and finish.
3) Step Three: Apply the product according to It’s TDS.
4) Step Four: Let cure.
5) Step Five: Perform post application test to assure results are achieved.
Benefits of Concentrates and How to Mix
- Reduces carbon footprint
- Reduces job site and landfill waste
- Reduces worker and supply chain fatigue
- Refer to the description on the packaging for dilution ratios.
- Pour contents of concentrate into an empty container. The container size should be the size of the finished amount of product.
- Fill the container with clean water – we recommend distilled water for best results.
- Mix lightly with a stir stick.

Substrate Uses and Anticipated Coverage Rates
Substrate porosity varies due to type of substrate and/or the age of the surface and its exposure to weathering. As a result, coverage rates may also vary. In addition, in certain applications, two coats may be required. Please contact us for coverage estimates. Best practices are to first perform a test application on the substrate, followed by a rilem tube test to ensure adequate coverage/absorption.
Refer to the product TDS for Surface Preparation and Application Methods.
