Water-Based Enhancer and Water Repellent Sealer
DECRA-SEAL NATURAL is low-VOC, water-based sealer that enhances the natural color and features of decorative concrete, pavers, unglazed tiles, and a variety of porous natural and artificial stone. DECRA-SEAL NATURAL is a penetrating water repellent that chemically bonds to the substrate, helping to increase the service life.
DECRA-SEAL NATURAL is designed for various applications, including interior, exterior, horizontal, and vertical concrete and masonry surfaces, pavers, unglazed tiles, and a variety of porous natural and artificial stone applications.
- Enhances and enriches the colors of the substrate.
- Does not create a glossy finish, preserving the natural look of the substrate.
- Excellent product for sealing concrete pavers.
- Matte finish.
- Repels water.
- Reduces water and salt penetration in the substrate.
- Low VOC.
1 Gallon (3.79 L) Units (4 per Case)
5 Gallon (18.93 L) Pails
55 Gallon (208.20 L) Drums
50 – 300 ft.2/gal. (1.23 – 7.36 m2/L).
Due to porosity, certain stone and block applications may require a significant increase in coverage rate or additional applications may be necessary. Always apply a test area to determine actual coverage rate. Coverage rate will vary greatly due to the porosity of the substrate.
When stored indoors in original, unopened containers at temperatures between 40° – 90° F (4° – 32° C), optimum performance and best use is obtained within one year of date of manufacture.
- Complies with CARB, U.S. EPA, LADCO, OTC Phase I and II, and SCAQMD VOC requirements.
VOC Content: <50 g/L
Surface Preparation … Use proper protection for the applicator and protect vehicles, property, plants, and all surfaces from product splash, residue, and wind drift. Surfaces must be clean and dry with all stains, oil, grease, dust, dirt, curing compounds, sealers, and other contaminants removed prior to application. Failure to remove contaminates will compromise the penetration and performance of the product. Best performance is achieved on a clean, thoroughly dried and absorbent surface. Excessive moisture inhibits penetration, reducing the service life and performance of the treatment. For optimum results, wait 14 – 28 days before applying DECRA-SEAL NATURAL to new concrete and masonry. For optimum performance, the moisture content of the substrate should be <4%. Always test for compatibility. Masonry joints must be checked and repointed where necessary. All caulking and sealants must be in good condition and the surface fully cured and thoroughly dry before application.
Application Method … An industrial sprayer, such as a Chapin 1949, with a spray nozzle that produces a flow of 0.1 GPM (0.379 LPM) under 40 psi (0.276 MPa) of pressure (or equivalent) is recommended. AVOID PUDDLING in low areas. If puddles occur, brush or roll them out. DECRA-SEAL NATURAL can also be applied using a lint-free roller or lambs wool applicator.
Horizontal Surfaces … Apply in a single pass. Completely saturate the surface and leave wet for 3 – 5 minutes. Then brush out or broom all pools and puddles and collect excess material from surface.
Vertical Surfaces … To ensure proper penetration, sufficient material should be applied to allow a flood of material to run down at least 8″ – 10″ (203 – 254 mm) below the spray pattern. Apply and saturate from the bottom up.
NOTE: Note: Some horizontal and vertical surfaces may need an additional coat(s) to achieve the desired appearance. When applying additional coats, always apply wet on wet; first coat should not be fully dry prior to the application of the subsequent coat.
Surface and Air Temperatures … Optimum surface and air temperature is 40° – 95° F (4° – 35° C) during application and eight hours after. If freezing conditions exist before application, let surface to receive treatment thaw.
Test Application … Always perform a test application in an inconspicuous area on each type of surface prior to full-scale application to determine suitability and final appearance. Test using the recommended application instructions. Let area dry thoroughly before inspection.
Drying Time … DECRA-SEAL NATURAL dries quickly. Drying times may be extended depending on application rate, temperature, humidity, and project conditions. Restrict foot traffic for at least six hours. Twelve hours is preferred. Restrict vehicular traffic for 24 hours. Water repellency properties should start developing within 24 hours. It can take up to 72 hours to develop full water repellency properties.
Cleanup … While DECRA-SEAL NATURAL is still wet, equipment may be cleaned with soap and water.
KEEP FROM FREEZING. DO NOT ADD OR DILUTE WITH ANY OTHER COMPOUNDS. Do not apply when air, material and surface temperatures are expected to fall below 40° F (4° C) within eight hours of completed application. Do not apply to surfaces with temperatures of <40° F (4° C) or 95° F (>35° C). Do not use on polished and hard-troweled surfaces. Not recommended for below grade application. Not designed to stop water penetration through cracks, defects, or open joints. This product will not provide gloss. Treated surface should be protected from rain and contaminates for 24 hours.
HEALTH AND SAFETY
Direct contact may result in mild irritation. Inhalation may cause irritation of the respiratory tract. Refer to safety data sheet for complete health and safety information.
