A clear drying sealer for chronically mildew prone painted surfaces. Most re-occurring mildew problems originate from film imbedded mildew, which cannot be completely removed by power washing or hand cleaning. TWP MILDEW SEALER film is impervious to mildew. When applied over existing mildew, it not only blocks the re-growth of existing surface mildew, but also enhances the later finish coat service life. The sealer has excellent adhesion over moderately chalky surfaces and serves as an excellent bonding primer to reduce peeling. The finish dries clear and quickly. This is an ideal product where mildew surface defacement and finish film service life and appearance is important. TWP MILDEW SEALER must be finish coated with a high quality latex finish.
The following data is a list of organisms against which we expect our cured sealant to provide inhibition under laboratory and field conditions. TWP Mildew Sealer incorporates mold and mildew resisting components, up to 300% more than required for some organisms, to make its dry film impervious to mildew and mold against many of the listed organisms. We have found this necessary, based on exterior exposure data.

- Aspergillus Flavus
- Aspergillus Niger
- Aureobasidium Pullulans
- Botrytis Fabae
- Chaetomium Globosum
- Chlorella Fusca
- Penicillium Citrinum

In summary, this product has an 18-year track record with no failures in performance expectations. It is especially effective when applied to articles (structural surfaces) to resist deterioration by mold fungus in high humidity areas. When applied as directed, TWP Mildew Sealer does not pose a health risk. The composition is free of known carcinogens.
Where to Use
Any interior or exterior previously painted wood, masonry, stucco, drywall or aluminum siding. The finish may be applied directly over light to moderate mildew contaminated surfaces. Although it is very efficient over heavy mildew (when black discoloration comes off with light hand wipe), washing the surface with a bleach solution is recommended for best results. Rinse after cleaner application. TWP MILDEW SEALER may be applied as soon as surface is dry to touch.
Mask windows when planning to spray apply. Caulk and fill nail holes prior to sealer application. When surface is peeling, remove loose paint and spot prime with sealer, feathering into solidly adhering paint, then apply sealer to entire surface. Excessive chalk and mildew may be power washed in conjunction with cleaning solutions. Surfaces, such as interior and exterior walls in bathrooms have a tendency to mildew quickly due to poor moisture barriers on older homes. If this has been a problem, install 5/8" vent plugs on the exterior surface bottom and top areas between wall studs.
Brush, roll or airless spray. When sealing lap siding make sure drip edges are coated. Do not apply this product to crumbly, badly weathered stucco. See local paint dealer for product recommendations.
TWP MILDEW SEALER is ready to be top coated when the film changes from milky white to clear, typically in 1-3 hours. The film may still feel tacky when ready for topcoat application. Always topcoat with a high quality 100% acrylic latex finish.
400-500 square ft./gallon on non-porous surfaces. 300-400 square ft./gallon over porous or rough surface textures.
