FEATURES AND BENEFITS OF NATURAL SHIELD

SEMCO’s 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.

Durability

Get the 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. Excellent chemical resistance and industrial strength finish allow Natural Shield to be used in an industrial environment.

UV and Alkali Resistance

Natural Shield is UV-resistant sealer and can be applied to multiple surfaces to give extra protection. Highly alkali resistant and effective against freeze-thaw damage.

Commercial Applications

Natural Shield’s performance allows to be used in commercial areas to protect your surface and decrease maintenance efforts.

Industrial Applications

Excellent chemical resistance and industrial strength finish allow Natural Shield to be used in an industrial environment.

Waterproofing Sealer

With its low water permeability, Natural Shield can be used in showers.

Increase longevity of your existing surfaces

Protects your investment, increases life of mortar, tiles, stucco, brick and natural stone surfaces.

Application Instructions

Natural Shield Application

STAGE 1 – REMOVAL OF DEBRIS

  • HOW : Sweep debris off surface and loose surface

PURPOSE : No debris in sealer

  • HOW : Use Natural Shield (water-based penetrating sealer)

PURPOSE : Creates flat finish:

1. Penetrating seal w/ chemical reaction
2. Waterproof
3. Moisture mitigation

STAGE 2 – SEALER APPLICATION

  • HOW : 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

PURPOSE : Ensures proper application. Does not allow to puddle, will create a white haze if puddled

  • HOW : Apply the first coat and DO NOT ALLOW THE SEALER TO DRY BEFORE APPLYING SECOND AND THIRD COATS. Do not allow to puddle

PURPOSE : Ensures penetration. If sealer dries before additional coats it may not bond properly

  • HOW : 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)

PURPOSE : Avoids hazing – ensures penetration

VERTICAL SURFACES

  • HOW : Apply the sealer with a 1/4” nap roller, HVLP sprayer, or airless sprayer with tip size 15. Start application from bottom to top to avoid runs in the sealer. Avoid over-spraying. Minimum of 3 coats is required to ensure maximum performance.

PURPOSE : Ensures proper sealing application, avoids runs in the sealer
