- Advantages
- Permanent sealing: existing and new hairline cracks are sealed on contact with water
- Protects against water, chloride and sulfate ingress
- Enhances resistance to chemical attack, carbonation and efflorescence, including diluted acid or alkali attack
- Does not affect bond with subsequent product applications
- Increases surface hardness (8 on Mohs scale) to approximately 20 mm (13/16”) depth
- Simple, fast and economical application compared to other systems
- Can be walked on six hours after first water curing
- Does not peel or scratch and can be polished
- No negative screed necessary
- Non-toxic and suitable for potable water storage structures
- Water soluble and complies with environmental, health & safety regulations
- 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
- Non - toxic & bio degradable
- Non - flammable
Applications & Uses

- 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.
- Surface Preparation
- Surface damage, such as honeycombs, voids, etc. must be routed out & repaired with PENECRETE MORTAR™
- Surface should be minimum 14 days old (28 days is recommended), clean, free of dust and dry (no damp areas!)
- Any formwork oil, curing compounds or previous treatments should be completely removed
- Temperature should be between 41° and 95°F (5° and 35°C.)
- Avoid application when rain is imminent or in heavy wind
- Old concrete and concrete affected by carbonation may need to be treated with calcium for adequate reaction
- 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. PENESEAL PRO® is ready to use and not to be diluted with water.
Application:
- Flood all cracks with PENESEAL PRO® at approximately 1 quart per 15 feet (1 liter per 5 linear meters)
- Apply the product to the surface to be treated at the recommended coverage rate
- Spray the product at low pressure and in low wind conditions
- 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
- Twenty-four (24) hours later, flood the surface with abundant water again
- Another 24 hours later, flood the surface with abundant water again
- After third flooding, the treated area can be ponded to verify the waterproofing performance
- Special Consideration
- 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
- In case the main purpose of application is floor hardening, use PENESEAL™ FH instead
- PENESEAL PRO® should not be used for negative side waterproofing. PENETRON® should be used for this application
- 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. To ascertain suitability, execute a trial on a small area or obtain concrete mix design from supplier. To increase suitability of such concrete, a calcium treatment may be applied to the surface. This can also be done to increase effectiveness on old and heavily carbonated concrete
- Do not spray PENESEAL PRO® onto glass, aluminum, wood or painted surfaces. In case this happens, remove the product with water
- Contact your Penetron representative for details. PENESEAL PRO® should not be used as a replacement or a solution for poor design, detailing and workmanship
- Typical Uses
PENESEAL PRO is ideal for concrete roofs, traffic bearing structures, and wherever concrete is directly exposed to the elements such as,
- Building exteriors
- Bridges & flyovers
- Runways & driveways
- Terraces & outdoor areas
- All exposed concrete surfaces
- Coverage
- 1 quart to 45-65 sq ft (1 liter to 4-6 m²)
- Rough and porous surfaces: 45 sq ft (4 m²)
- Very smooth, dense surfaces: 65 sq ft (6 m²)
- Normal surfaces: 55 sq ft (5 m²)
- Cracks: additional 1 quart per 15 feet (1 liter per 5 linear meters)

Technical Details & Test Data
- Comparison
- Penseal Pro Mode of Operation
Step 1: Penseal Pro penetrates below the concrete surface, creating a sub-surface barrier
Step 2: Thermal stress causes new cracks, creating a waterproofing problem
Step 3: PENESEAL PRO reacts with water and concrete to seal new cracks
Safety & Health
- Caution
Avoid skin and eye contact. If contact is made, flush areas with lots of water. Protective gloves should be worn. Breathing apparatus is advised if applied in enclosed environments.
