DESCRIPTION PENESEAL PRO™ is a spray applied liquid sealer which forms a sub-surface barrier that protects concrete against water penetration and seals hairline cracks. When sprayed onto a thoroughly cleansed concrete surface, it will react with the concrete to form a sub-surface gel. This gel seals the pores, capillaries and cracks. As long as water is present, the product will remain active and seal future hairline cracks. RECOMMENDED FOR ADVANTAGES Seals existing cracks. New hairline cracks will be sealed on contact with water. Protects against water, chloride and sulphate ingress; increases resistance to chemical attack and carbonation; PENESEAL PRO™ is not to be used in areas where strong acid or alkali attack can be expected. Sub-surface nature does not affect the adhesion of subsequent products. Increases surface hardness, approximately 13/16 in (20.6 mm depth), to 8 on Moh’s scale. Simple, fast and economical application compared to alternative membrane systems. Trafficable within 6 hours after first water curing without affecting protection. The product will not peel or scratch and the treated surfaces can be polished. No negative screed necessary. Non toxic - can be applied to potable water containing structures. Ease of repair - if large cracks continue to be present or re-appear during the life of the structure they are easy to find and fix; no tedious lifting and removal of membrane to find the cracks is necessary. Because of its ability to withstand thermal stress, PENESEAL PRO™ is ideal for concrete roofs, podium decks, bridge decks, terraces, traffic bearing structures, runways, and driveways. In short, everywhere concrete is directly exposed to the elements and considerable thermal stress can be expected. For below ground projects, Penetron is the proven system of choice. DIRECTIONS FOR USE Application Methods: The product can be applied using simple hand spraying equipment for small areas to motorized spray units for large projects. With a simple backpack spray unit, coverage of 120-180 sq yards (100-151 m²) per hour can be achieved. After application all equipment should be thoroughly cleaned with water. Contact your Penetron International representative for further details on spraying equipment. Tools: Low-pressure sprayer, soft bristle broom, squeegee, and water hose. Application: Step 1. Flood all cracks with PENESEAL PRO™ at approximately 1 quart per 15 feet (1 liter per 5 linear meters). Step 2. Apply the product to the surface to be treated at the recommended coverage rate. Step 3. Spray the product at low pressure and in low wind conditions. Step 4. When surface is dry to the touch (2-6 hours after application) flood the surface with abundant water. If it rains before the product is dry, a second application is required once the surface is dry. Step 5. Twenty-four (24) hours later, flood the surface with abundant water again. Step 6. Another 24 hours later, flood the surface with abundant water again. Step 7. After third flooding, the treated area can be ponded to verify the waterproofing performance.

1 quart to 45-65 sq ft (1 liter to 4-6 m²): 45 sq ft (4 m²) for rough and porous surfaces, 65 sq ft (6 m²) for very smooth, dense surfaces and 55 sq ft (5 m²) for normal surfaces. Cracks: additional 1 quart per 15 feet (1 liter per 5 linear meters). Available in 5 gallon (19 L) pails, 55 gallon (208 L) drums and 275 gallon (1041 L) containers. STORAGE / SHELF LIFE Two years when stored in sealed drums. Keep pails closed and avoid exposure to heat and direct sunlight. DO NOT ALLOW TO FREEZE! SPECIAL CONSIDERATIONS PENESEAL PRO™ is not suitable for the repair of structural or design cracks. For...
