SB-6725 SurfacePRO Classicis a proprietary two-part water reducible, clear, aliphatic urethane sealer and joint sand stabilizer. SB-6725 is specially formulated with an antifungal designed to help inhibit the growth of mold, moss and algae on the sealer film when applied to horizontal or vertical surfaces. SB-6725 is a multi-use product: it enhances with a semi-gloss finish producing a wet look, provides good surface protection and joint sand stabilization. This product can be used inside and outside on old and new surfaces. Optimal results when performing same day cleaning, sanding and sealing with SB-6725, can be achieved when following the recommended application process. SB-6725 provides a non-yellowing protective layer on the surface that offers great durability and resistance to mild acid, alkali, chemicals and salt attacks. SB-6725 will increase the stain resistance of the surface and allow easier cleaning, maintenance, and extended wear. On new concrete, mortar, grout or overlays, it is recommended to wait 7 days before applying SB-6725 to allow for curing. SB-6725 is a water-based two component product that requires mixing and dilution. Once mixed, it has the consistency of water and is milky white when applied and dries clear. Cured sealer is freeze resistant to -60°F (-51°C) and is stable up to a temperature of 180°F (-51°C).
Ideal for concrete and clay pavers, flat and stamped concrete, or natural and manufactured stone. Also suitable for masonry, retaining walls,porous or unglazed tile and terrazzo. Recommended for high traffic areas where high durability and superior chemical resistance is desired. NOT recommended for marble, granite, ceramic tile or porcelain.
A test area is always recommended to determine product suitability and compatibility with your specific surface before use and also if desired results are achievable. Due to the inherent variability of natural stone and clay products, long term performance may vary. Please consult with us prior to sealing if there are concerns.
Sealing with joint stabilization
80 – 120
7.4 – 11.1
Sealing only without joint stabilization
200 – 300
18.6 – 27.9
*Per gallon once mixed and diluted. Single application. Actual coverage may vary depending on type, age, condition, joint size and porosity of the surface, application method and site conditions such as temperature. For more uniform coverage, a second coat must be applied after the first coat has dried to the touch.
RECOMMENDED FOR PROFESSIONAL USE ONLY
WARNING: Once applied, SB-6725 cannot be chemically stripped from the applied substrate. If removal is necessary, sand-blasting or other mechanical methods must be used. Use product at own risk.
TEST FIRSTon a small inconspicuous area to determine the suitability and if desired results are achievable with this product on your specific surface. (Caution: product is difficult to remove.) The surface should be thoroughly clean and free from oil, dust, loose material and previously applied sealer. Remove and kill growth of any mold, mildew, fungus or algae prior to application of sealer. If needed, prepare surface with Surebond Cleaners before sealing. When using SB-6725 as a sealer without joint stabilization, it can be applied to a damp surface with no ponding or pooling of water present. For applications with joint stabilization, allow the surface to dry. Cover/protect nearby landscape, vehicles and buildings from overspray during application.
Preparation for Joint Stabilization
Surface must be dry for ease of installation. For optimal joint stabilization, the paver joints should be no more than ¾” wide and filled with dry correctly graded joint sand that meets the ASTM C144 standard. The top level of the sand should not exceed the bottom of the chamfer or 1/8” below the surface on non-beveled or tumbled paver surfaces. Compaction is recommended after sweeping sand into joints to minimize voids in sand joints. Use a vibratory compactor with neoprene pad or vibratory roller to consolidate the joints and. A leaf blower is recommended to remove dust, debris and fine particles from the surface before sealing. Do not use wet joint sand because it will severely diminish joint stabilization.
Full Kit Mixing Instructions
SB-6725 is a two-part product that comes packaged in a kit which contains 4.5 gallons of Part A and one gallon container with .5 gallons of Part B.
Variable Speed Drill
Blend the container of Part B into the pail of Part A with a drill and paddle mixer on low speed for 1-2 minutes. Do not whip air into the mixture.
Pot Life: SB-6725 Mixture (combined Parts A and B) has a pot life of 90 minutes which varies based on temperature and humidity. Do not mix more material than can be used in a 90 minute period. Do not store SB-6725 Mixture. If less than the entire kit is needed, see Project Calculator for more information.
SB-6725 Dilution Instructions
The SB-6725 Mixture is a super concentrated sealer which requires water dilution dependent on desired sheen and joint stabilization.
Tools Needed: • Variable Speed Drill • Paddle Mixer • One Clean Five Gallon Pail
Before diluting, using the SB-6725 Marking Label (found on Part A pail) as a guide, mark D1 on the pail.
Apply when day and night temperatures are between 45°F – 95°F. To cool hot surfaces, mist with water without ponding or pooling prior to applying SB-6725. Avoid windy conditions to keep sealer spray from drifting. SB-6725 is a two part product: read and follow the Mixing and Dilution Instructions before applying. Use product coverage calculators to determine the amount of material required for the project; material coverage will depend on the surface type and its porosity. Apply SB-6725 after dilution with a low pressure, high volume sprayer such as an airless sprayer or hand held garden sprayer (pump-up). Do not apply too thick to avoid air bubbles in the sealer film. Saturate the surface to ensure proper penetration. Use a squeegee or foam roller to provide uniform coverage over the entire surface area and to remove excess sealer. For exterior applications with joint stabilization, the surface and joints should be flood coated using a low pressure, high volume sprayer following the coverage guidelines. Use a soft foam squeegee to direct excess sealer into the joints. It is recommended to back-roll to even out the sealer on textured or uneven surfaces to eliminate pooling. For optimal performance a second application should be applied. Second coat should be applied as soon as practical after the first application has visually cleared and is dry to the touch, which is usually within one hour. Second application must be applied prior to full cure (see Dry Time for more information). With interior applications, SB-6725 may be carefully sprayed or applied with a slit foam roller taking care not to roll back and forth excessively.NOTE:To minimize slipperiness on travertine, pool decks and very smooth surfaces, use an anti-slip additive.
Surface will be dry to the touch in 1-2 hours assuming the air temperature is between 65°F – 85°F at 50% relative humidity. Low surface or air temperature will extend dry time. Protect surface from dust, rain, condensation and traffic while drying. Full cure will take 24 – 36 hours depending on weather and site conditions. Once surface has visually cleared and dried to the touch, area can be open to foot traffic in 24 hours and vehicular traffic in 48 hours depending on weather and site conditions.
For tools and equipment, use soap and water before product is allowed to dry.
