R214 Photocatalytic Air Purification Sealer Datasheet

Proven and tested to reduce harmful pollution

Dirt Defence Photocatalytic Sealer can be applied to concrete, natural stone, brick, roofing slates etc. It is ideal for use on facades, path and pavements, motorway bridges, barriers and ramparts, neutralising harmful NOx gases with photocatalytic reaction of Titanium Dioxide and natural sunlight to create harmless substances: water, CO2 and nitrates.

• Invisible and environmentally friendly water based product which forms both a matrix of surface protection
• Dramatically reduces voc’s, nitrous oxide, odours and resists the growth of mould.
• Removes airborne spores and allergens to help prevention of asthma and breathing problems
• This unique formulation does not become ‘clogged’ due to its self cleaning properties and therefore retains its efficiency for 20+ years.

Test a small inconspicuous area before proceeding, to ensure finish, compatibility and performance are acceptable. Ensure the surface to be treated is clean and free from dust, dirt, oil, efflorescence, organic growth, grease and old coating films. All cleaning detergents should be thoroughly rinsed away Ensure all cracks are repaired using a concrete/mortar repair system.

• Apply using a low pressure spray, brush or roller.
• Applying the product from bottom to top on vertical surfaces taking care not to let the product run.
• All surfaces must be treated to saturation ‘wet on wet’ to ensure 100% product efficiency. This will vary dependant on the substrate and treating a small trial area is recommended to calculate true consumption.
• Allow to fully cure before subjecting to heavy use

Remove as much product as possible from application equipment before cleaning. Clean tools and equipment immediately after use with water.

For Health & Safety instructions, first aid measures, spillages and disposal instructions, see separate Health & Safety Data Sheet (MSDS).

• Independently tested for weathering and nox gas removal.
• Non-visible
• Does not effect slip resistance
• Non hazardous - solvent and silicone free
• Fully biodegradable
• Uv resistant
• The treated surface is protected from algae growth due the self cleaning action of the product

Water repellence is evident after initial curing but may take up to 7 days to reach 100% efficiency.

Coverage depends on the porosity of the substrate. Below is an indication:

Architectural Concrete 5 m2 per litre
Block Paving 5 - 8 m2 per litre
Natural Stone 2 - 5 m2 per litre
Granite 8 - 16 m2 per litre
