Lithi-Tek 9500 Ultra Concentrate - 1 Gallon (Makes 5 GALLONS) Penetrating Concrete Sealer, Waterproofer Plus Densifier

At a Glance

Product Details:

• 100% reactive - Hardens, densifies and waterproofs concrete, resisting water absorption, prolonging service life
• Increases abrasion resistance - Tightly binds together concrete reducing concrete dusting.
• Small molecular structure - Allows for deeper penetration and increased performance
• Prevents ASR attacks by preventing the ingress of water
• Provides increased protection - As a hydrophobic barrier to prevent future penetration of water and soluble aggressive agents
• Reduction of water ingress - Moisture intrusion and vapor transmission
• Does not alter surface appearance - The treated surface is natural, tack-free and slip-resistant and dries completely clear
• Resists organic growth - lichen, efflorescence and dirt pick up
• 100% breathable - Allows moisture to escape without damaging the sealer
• Water-based - Proprietary formula with no odor, no VOC’s
• Excellent penetration depth - Into any concrete substrate
• Improves durability - Prevents capillary uptake of water and the aggressive substances dissolved in it
• Natural flat finish - Does not change concretes surface appearance
• Super UV stable - Resistant to ultra-violent radiation, will not yellow or fade

Surface Preparation: New “green” concrete must be properly cured. Concrete should obtain 80% of design strength, typically achieved within 14-28 days. The concrete substrate must be structurally sound and clean of oil, grease, dirt, wax, curing compounds, efflorescence, paints, previous sealers, adhesives and other contaminants that might interfere with the penetration of the sealer. Power wash, acid etch or mechanically scarify as necessary to achieve the desired surface condition. If acid was used to clean the concrete, neutralize the surface and rinse with water prior to application. Allow for proper dry time before application. The surface-zone moisture content of the concrete should not exceed 4% wt. Do not apply if standing water is visible. Surface and air temperatures must be at least 40°F during application. Surface and air temperatures should not exceed 95°F. Do not apply when temperatures are expected to fall below 32°F within 8 hours or when rain is expected within 12 hours following application. Keep material from freezing. If freezing conditions exist before application, let the substrate thaw before application. Do not apply during inclement weather or when inclement weather is expected within 12 hours. Crack, patching and expansion joint sealants can be applied before application; always test for compatibility and adhesion. Protect people, property, vehicles, window glass, roofing materials, plastic products, shrubbery, landscaping and all surfaces not set for treatment from overspray.

Application: Always test a small area before application to ensure desired performance, aesthetics, coverage rates and to verify application technique. Let test area dry thoroughly, 5-7 days, before inspection. Always mix the concentrate with 4 parts water prior to application. Distilled water is recommended for maximum performance. Stir material throughly before and during application. Two wet-on-wet coats are needed to ensure complete coverage. Apply with a roller, brush or low-pressure non-atomizing sprayer. Apply in a uniformed manner not exceeding the substrates absorption rate and let the first coat penetrate for 5-10 minutes then reapply a second coat in the same manner. Less material will be needed for the second coat. Roll or broom out any puddles until the sealer penetrates the substrate. Do not over apply (Over application may results in whitening of the surface). If it starts to rain, stop treatment and cover the impregnated areas.

Dry Time: Typical drying time is 4-6 hours at 70°F and 50% relative humidity. Cooler temperatures or higher relative humidity can extend the drying time. Treated surfaces will be ready for pedestrian and vehicle traffic within 24 hours. Water repellency will continue to develop within 7 days of application.

Clean Up: Clean equipment and tools with hot soapy water. Unused or old material may be disposed of in a waste disposal site in accordance with local, state and federal laws.

Precautions/Safety: Avoid contact with skin, eyes and clothing, do not take internally. Use appropriate safety equipment during application and handling. Please refer to the safety data sheet (SDS) for additional precautionary instructions before use.

Best Performance: Proper application is the responsibility of the user. Will not inhibit water penetration through unsound or cracked surfaces with defective flashing, caulking or structural waterproofing. Do not use on extremely porous concrete or masonry such as CMU block. Do not over apply. Sealer is highly reactive. Excess material may result in a a white residue or discoloration. Does not protect against equipment leaks such as oils and hydraulic fluids. Make sure the most current versions of product data sheets and SDS are being used.

Coverage: Lithi-Tek 9500 is concentrated. 1 coat: 1000 - 1200 square feet. 2 coats: 500 - 600 square feet. Variations in texture and porosity of substrate will affect the coverage and performance of the product.
