What Is Agar Duro?
Agar Duro gives a super-glossy polished finish to slate, terrazzo and marble floors as well as every kind of timber and vinyl surface. It is applied neat as a film-forming floor sealer, buffing up to a high-gloss shine and responding to buffing machines across a wide speed range.
Key Benefits of Agar Duro
- Extremely glossy, high-shine finish
- Versatile: suitable for marble, terrazzo, slate, vinyl and timber floors
- Buffs with machines from 400 to 2500 rpm
- Faster coat system than some other Agar gloss finishes, with just 30 minutes between coats
- Non-flammable, water-based formula
How Does Agar Duro Work?
Agar Duro is applied neat, straight from the container, and dries to form a glossy film that seals and protects the floor while delivering a high-shine finish. It responds well to buffing across a wide machine speed range, from slow buffers through to high-speed machines up to 2500 rpm.
How to Apply Agar Duro
On marble, terrazzo and other stone floors, first apply 1-2 coats of a suitable base sealer (2 coats if the stone is very porous), allowing around 1 hour drying time between base coats. Then apply 2-4 coats of Agar Duro, allowing 30 minutes drying time between coats.
On vinyl and timber, dry-burnish the floor before the first coat, then apply 4-6 coats of Agar Duro, allowing drying time between each coat.
| Surface | System |
| Marble, terrazzo, stone | 1-2 coats base sealer, then 2-4 coats Agar Duro (30 min between Duro coats) |
| Vinyl and timber | Dry-burnish first, then 4-6 coats Agar Duro |
Agar Duro covers approximately Duro covers 40-50 m² per litre with each coat, and may be buffed with machines from 400 to 2500 rpm, covering slow-speed, medium-speed and high-speed equipment.
What Surfaces Can Agar Duro Be Used On?
It is made for timber and vinyl surfaces of all types, and for slate, terrazzo and marble floors. It is not suitable for ceramic or porcelain tiles; ask our team about Agar Stone Block as a suitable alternative for those surfaces.
