How to apply SEMCO Natural Shield?
- Surface Preparation
- Execute appropriate preparation method to suit your needs before application. Reference to the SEMCO SIP Manual under the Surface Preparation Section.
- Sweep all debris off surface to ensure proper bond.
- Application
- Apply the sealer with a 1/4” nap roller, HVLP sprayer, pump sprayer, or airless sprayer with tip size 17. Minimum of 3 coats are required to ensure maximum performance
- Apply the first coat and DO NOT ALLOW THE SEALER TO DRY BEFORE APPLYING SECOND AND THIRD COATS. Do not allow to puddle
- Repeat the application to a minimum of 3 coats. Additional coats may be required depending on the porosity of the surface (X-Bond requires, 3 coats only, other surfaces such as concrete or block may require additional coats)
- Tools needed
- Airless sprayer with tip size 17
- 1/4” nap roller
- OPTIONAL : pump sprayer
Drying / Cure Times


Natural Shield is an exceptional waterproofing sealer that excels under the most demanding circumstances. Natural Shield’s low molecular weight allows for excellent penetration. Natural Shield fills into the pores of the substrate, in which chemical reaction follows, that creates a solid, but breathable membrane. Natural Shield provides long lasting protection for a vast array of surfaces in which it leaves a natural finish. It has durability and performance of a solvent-based system, but with the easy application and clean-up of water-based products. Natural Shield’s performance allows to be used in commercial areas to protect your surface and decrease maintenance efforts.
