Description
The Semi-Transparent Stain addition to the Loxon family is ideal for large commercial concrete structures or horizontal surfaces. The innovative formula allows you to offer customers a semi-transparent look that both repels water and allows moisture vapor transfer for early blister resistance. The product provides excellent adhesion, hides surface imperfections and penetrates deeply for tough protection that resists peeling and flaking. It features excellent efflorescence resistance and guards against color fading to provide outstanding color uniformity for an attractive finish.
Material Use
Product Code: LX31T0075 Tint Base
Manufacturer: Sherwin-Williams
This product is a water-repellent stain formulated specifically for vertical concrete and masonry surfaces. It enhances aesthetic appearance while providing protection against moisture intrusion. Designed for use on tilt-up concrete and other architectural concrete surfaces, it is ideal for both new construction and restoration.
System Components
This material is typically applied as a standalone stain in a minimum two-coat system.
- No primer is required, but surface must be porous and adequately prepared.
- No reduction is necessary; product comes ready to apply.
- Compatible application tools: airless spray, brush (nylon-polyester), or roller (3/8"–1/2" synthetic nap).
- Tinting must be done using Sherwin-Williams CCE tint system (1/2–4 oz per gallon).
Applications
Recommended for vertical surfaces such as:
- Tilt-up and poured-in-place concrete
- Precast concrete
- CMU (Concrete Masonry Units), split-face and fluted block
- Block and stucco walls
- Parking garage supports
- Stadium supports
- Bridges and bridge structures
Suitable for both interior and exterior applications.
Application Details
- Coating Thickness / Coverage:
- Smooth surfaces: 300–400 sq. ft./gal
- Rough surfaces: 150–300 sq. ft./gal
- Apply two coats for optimal color uniformity and water repellency. A third coat may be needed on highly textured surfaces.
- Surface Prep:
- New Concrete: Must cure for at least 7 days at 75°F. Surface must absorb water to ensure porosity. Acid etching or mechanical abrasion may be required.
- Previously Painted: Remove all loose paint; any remaining coating may reduce system longevity.
- Stucco: Requires 30-day cure.
- Mildew: Must be removed with bleach solution before staining.
- Temperature Limits:
- Air and surface temp must be between 50°F and 90°F during application.
- Drying / Curing Times (@77°F, 50% RH):
- Touch dry: 1 hour
- Recoat: 2 hours
- Full cure time not explicitly stated—follow Sherwin-Williams standard guidance if needed.
- Pot Life: Not applicable (single-component, no mixing required).
- UV Performance:
- Provides good UV resistance, but not specified as "UV stable" post-cure.
- VOC Content:
- Less than 50 g/L (0.42 lbs/gal); compliant with major environmental regulations including OTC, CARB, SCAQMD, and LEED v4 & v4.1 VOC requirements.
Special Notes
- Not intended for use on wood or horizontal surfaces (e.g., roofs) where water may collect.
- Does not waterproof porous materials such as concrete block—only provides water repellency.
- Final appearance is affected by surface porosity, texture, and application method.
- Shelf Life: 36 months unopened.
Vehicle Type: Styrenated Acrylic
