Strippable Masking Temporary Protective Coating

Sure Klean Strippable Masking — Temporary Protective Coating for Glass, Metal & Polished Stone

Sure Klean Strippable Masking is a water-based, temporary protective coating formulated to shield glass, unpainted metal, and polished stone from masonry cleaners during nearby cleaning operations. Applied as a thick white liquid with a brush, roller, or airless sprayer, it dries to form a watertight film that guards sensitive surfaces against splash, wind drift, and incidental contact with acidic and alkaline cleaners. Sold in 5-gallon containers, it is engineered for professional use on commercial and institutional masonry restoration and cleaning projects.

Unlike traditional tape-and-plastic masking methods, Strippable Masking delivers a continuous, conforming film that peels off in large sheets or pieces once cleaning is complete. Its water-based, low-VOC formulation eliminates solvent odor on the job site and is safer for sensitive substrates such as rubber and neoprene gaskets than comparable solvent-based products.

Key Features & Benefits

Easy Application and Removal

Strippable Masking applies quickly with a brush, roller, or airless sprayer and dries to a continuous protective film. When the cleaning project is done, the coating peels off in large sheets or pieces, reducing labor time compared to removing traditional tape-and-plastic masking systems.

Superior Protection vs. Tape-and-Plastic

The conforming liquid film seals out splash, wind drift, and incidental contact with both acidic and alkaline masonry cleaners. This level of coverage is difficult to achieve consistently with tape and plastic sheeting on irregular or detailed surfaces.

White Pigment for Visual Verification

The white pigment clearly distinguishes treated areas from untreated ones at a glance. Contractors can confirm complete coverage before cleaning begins, reducing the risk of missed areas and potential surface damage.

Safer for Sensitive Surfaces

The water-based formula is safer for rubber or neoprene gaskets than similar solvent-based products. This allows the product to be applied around window and door assemblies without concern for gasket degradation that solvent-based coatings can cause.

Allows Continued Use of Windows and Doors

Strippable Masking is formulated to allow double-hung windows and doors to remain operable during periods when active cleaning is not taking place. This is a meaningful advantage on occupied buildings where access and ventilation must be maintained throughout the project.

No Solvent Odor — VOC Compliant

With a VOC content below 50 g/L, Strippable Masking meets all national, state, and district AIM VOC regulations. The absence of solvent odor makes it suitable for use in occupied or semi-occupied buildings where air quality is a concern.

Common Applications

Masonry Restoration and Cleaning Projects

Applied to adjacent glass, metal, and polished stone surfaces to protect them from acidic and alkaline masonry cleaners used on surrounding substrates.

Window and Door Frame Protection

Coats glass panes, frames, and associated gaskets to prevent contact with cleaning solutions during exterior building wash-down operations.

Polished Stone Protection

Applied over polished stone surfaces — such as lobby entries, column bases, or decorative panels — located near masonry being cleaned, where chemical splash or wind drift poses a damage risk.

Unpainted Metal Surface Protection

Shields unpainted metal elements such as railings, trim, or mechanical equipment from incidental contact with masonry cleaning chemicals.

Application Instructions

Preparation

1. Protect people, vehicles, property, plants, and all surfaces not set for application from product splash, rinse, residue, and wind drift. Divert pedestrian and auto traffic if necessary.
2. Test all surfaces that may come in contact with Strippable Masking for compatibility. Immediately rinse any non-target materials with large quantities of water.
3. Tape over all exposed caulk prior to application.
4. Ensure surfaces to be protected are clean and dry. Grease and oil reduce adhesion and may cause the protective film to fall off. Note: oxidation on metal surfaces can make final removal of the film difficult — contact the manufacturer for cleaning recommendations.
5. Confirm air and surface temperatures are between 40–90°F (4–32°C) for best results.

Mixing and Equipment

1. Mix Strippable Masking thoroughly with a low-speed drill and a clean mixing paddle before use. Apply as packaged — do not dilute or alter.
2. Roller application: use a 3/4-inch (19 mm) nap roller.
3. Brush application: use any brush rated for water-based acrylic paints.
4. Airless spray application: use chemical-resistant fittings with a minimum tip size of 0.015–0.019 inches. Remove all filters in sprayer and gun. Recommended sprayer specifications: Tip Size 0.015–0.019 in, Fan Size 8–12 in, Pressure 100–2000 psi, Flow Rate 0.20–0.30 gal/min, Hose Length 100 ft maximum, Motor 5/8 hp.

Application

1. ALWAYS TEST a small area of each surface type to confirm suitability and desired results before beginning overall application. Use the same equipment and procedures planned for general application. Allow the test area to dry 3–7 days before inspection and approval. Keep the test panel available for comparison throughout the project.
2. Apply two coats to surfaces requiring protection, following coverage rate guidelines of 175–275 sq ft per gallon per 6–10 wet mil application (3–5 dry mil).
3. Allow coating to dry fully before cleaning operations begin.
4. Once cleaning is complete, peel the dried coating off protected surfaces in large sheets or pieces.

Storage and Handling

1. Keep from freezing. Store in a cool, dry place at 45–100°F (7–38°C).
2. Always seal container after dispensing. Do not double stack pallets.
3. Do not alter or mix with other chemicals.
4. Dispose of unused product and container in accordance with local, state, and federal regulations.
