Safecoat MexeSeal Low-VOC Interior/Exterior Masonry Sealer
AFM Safecoat MexeSeal is a very low odor, water-based, medium-gloss, clear very low VOC masonry sealer. It is suitable for use on porous interior tile or masonry surfaces where oil and water repellency are desired. It is ideal for long term protection against food, oil and water stains on residential or commercial floors. It is suitable for re-coating many water-based sealers, and is slip and scuff resistant. Non-hazardous and non-flammable, it has been safely used by and for the chemically sensitive.
AFM Safecoat MexeSeal is non-toxic, low-VOC and non-flammable masonry sealant, a total replacement for high-solvent content systems. Contains 36g/l of VOCs.
Usage
AFM Safecoat MexeSeal is recommended the following substrates:
- Unpolished marble.
- Limestone.
- Granite.
- Sandstone.
- Slate.
- Fireclay (brick, tile, terra cota, pavers).
- Concrete (brick, tile, precast panel, poured).
Always test in small, inconspicuous places before full application. Safecoat MexeSeal is generally not suited for polished surfaces. Not recommended for use on modern Saltillo or quarry tiles without special care. Saltillo or quarry tiles generally contain salts and other contaminants sensitive to application of water-based products. White efflorescence flushing may occur. It may be necessary to repeatedly remove contamination and repeat MexeSeal application until all contaminants are extracted.

Coverage
One gallon of AFM Safecoat Mexeseal covers approximately 300 square feet in one coat depending on surface porosity.
Surface Preparation
Remove loose or peeling paint and scuff sand the surface (to create surface profile). All surfaces must be clean, sound, dry, and free of any dirt, dust, oil, wax, grease, mildew, mold and other contaminants and debris. New cementitious surfaces should age at least thirty days and have a pH below 10 before coating. Scrub surface with a solution of SafeChoice Super Clean and water. Use 2-6 oz. of SafeChoice Super Clean per gallon of water. Triple rinse to assure cleaner is completely removed. For the best adhesion on smooth surfaces with no surface profile, acid-etching may be required, followed by completely neutralizing the surface. Use extreme caution when working with acid and follow label and MSDS precautions. All acid residual must be removed prior to coating. Surface pH should be 7-10 for best results. Test surface porosity and profile by dropping water onto dry surface. If water drops fail to penetrate quickly, surface may need additional attention to create proper surface profile. Test for surface cleanliness by applying a strong tape (such as duct tape) to the cleaned areas and pull back up. The tape must be clean and free of any concrete dust or dirt. If particles or a white residue are still present, remove them completely with additional scrubbing, rinsing and possibly etching.
Application
To assist in quick drying/curing, bring adequate ventilation and air flow to the work area. Before using, stir Safecoat Mexeseal thoroughly but without excessive agitation so as to avoid air bubbles. Then apply as is, using a squeegee brush, roller, spronge or appropriate spray equipment. Apply in thin coats. Allow at least 2 hours to dry between coats. For best results, this product should not be reduced. Two or more coats may be needed depending on porosity of masonry product. Apply only to a completely dry substrate. Correct application will often slightly deepen color or existing surface. Note: these instructions are intended to be general only and not exhaustive. The applicator should determine which preparation and techniques are best suited to the specific surface.
