Description

Dura Shield Concrete Densifier, Dustproofer & Surface Hardener

Dura Shield is a ready-to-use, water-based concrete densifier and surface hardener designed to reduce concrete dusting, strengthen the surface and make floors easier to clean and maintain.

Its sodium-silicate formulation penetrates the concrete and reacts with calcium hydroxide within the slab, creating a harder and more durable surface. Dura Shield is suitable for new or existing concrete and can also help restore lightly rain-damaged or dusting slabs.

With zero VOCs, good penetration and a breathable finish that allows trapped moisture to escape, Dura Shield is a cost-effective treatment for commercial, industrial and residential concrete surfaces.

Features & Benefits

• Hardens and densifies concrete surfaces
• Reduces concrete dusting
• Helps make concrete easier to clean
• Suitable for fresh and established concrete
• Can assist with rain-damaged or lightly deteriorated concrete
• Suitable for internal and external applications
• Allows trapped moisture to escape
• Ready to use with no dilution required
• Water-based, non-flammable formula
• Zero VOC content
• Meets Green Star Building requirements
• Cost-effective treatment for large concrete areas

Typical Applications

Ideal for:

• Warehouse and factory floors
• Basement and multi-level car parks
• Manufacturing facilities
• Commercial and industrial hardstands
• Workshops and storage areas
• Driveways
• Dusting concrete floors
• Lightly rain-damaged concrete

Approximate Coverage

Coverage depends on the condition and finish of the concrete:

• Damaged or heavily dusting concrete: approximately 2-4m² per litre
• Lightly broom-finished or burnished concrete: approximately 8-12m² per litre
• Concrete walls: approximately 10-15m² per litre

Dusting or damaged slabs may require two to three coats.

Application

Apply directly from the container using a low-pressure sprayer. Keep the entire surface wet for approximately 20-30 minutes, spreading the material evenly with a soft-bristle broom or microfibre mop.

After approximately 30-45 minutes, thoroughly remove all excess material using fresh water and a squeegee, mop or clean white rag. Excess product must not be allowed to dry on the surface, as it may cause discolouration.

Always test Dura Shield on a small section and allow it to cure before treating the complete area.

Important Information

• Apply between 10°C and 35°C
• Do not dilute or apply to wet concrete
• The surface must be free from contaminants and curing compounds
• Dura Shield may darken or alter the appearance of concrete
• Not suitable for natural stone
• Severely damaged or disintegrating concrete may require mechanical repair
• Concrete treated with Dura Shield must be mechanically ground before applying sealers, coatings, adhesives or glues
• Always consult the current Technical Data Sheet before use
