Overview
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.
Applications
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.
Advantages
- Seals existing cracks. New hairline cracks will be sealed on contact with water.
- Protects against water, chloride and sulfate 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 20.6 mm (13/16 in) 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.
- Nontoxic: can be applied to potable water containing structures.
- Ease of repair: if large cracks continue to be present or reappear 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.
Coverage
- 1 liter to 4 to 6 m² (1 quart to 45 to 65 sq ft)
- Rough and porous surfaces: 4 m² (45 sq ft)
- Very smooth, dense surfaces: 6 m² (65 sq ft)
- Normal surfaces: 5 m² (55 sq ft)
- Cracks: additional 1 liter per 5 linear meters (1 quart per 15 feet)
Application notes
PENESEAL PRO® is ready to use and not to be diluted with water. Surface should be minimum 14 days old (28 days is recommended), clean, free of dust and dry. Temperature should be between 5° and 35°C (41° and 95°F).
Special considerations
- PENESEAL PRO® is not suitable for the repair of structural or design cracks. For cold joints, expansion joints, penetrations and pour joints, appropriate joint treatment products such as PENECRETE MORTAR™, waterstops, elastomeric sealants, etc., need to be applied in addition to the PENESEAL PRO® treatment.
- PENESEAL PRO® can be used on concrete that contains fly ash, slag or silica fume, as long as these ingredients do not exceed 30% of the total cementitious materials in the concrete mix.
- PENESEAL PRO® should not be used as a replacement or a solution for poor design, detailing and workmanship.
- PENESEAL PRO® should not be used for negative side waterproofing. PENETRON® should be used for this application.
- In case the main purpose of application is floor hardening, use PENESEAL™ FH instead.
