PRO-601 FINO Contact Primer is a ready-to-use primer designed for use before the application of FINO microcement. Formulated with special polymers and quartz aggregate, it creates a high-adhesion surface on difficult, smooth and low-absorption substrates and can also help fill minor cracks, scratches and surface imperfections. It helps improve the bond of subsequent layers and is suitable for microcement and decorative plaster applications. It is also waterproof and frost-resistant.

Intended Uses

PRO-601 FINO Contact Primer is suitable for internal walls and floors and can be applied to surfaces including plasterboard, OSB, MDF, smooth concrete, ceramic tiles, terrazzo, glass, linoleum and rigid vinyl. The data sheet also refers to furniture boards, particleboard, old tiles, walls and floors, and states that it is suitable for both indoor and outdoor use. Where improved crack bridging is required, reinforcing mesh may be embedded into the wet layer.

Why Choose PRO-601 FINO Contact Primer?

• Creates a high-adhesion surface on smooth and low-absorption backgrounds
• Suitable before FINO microcement and decorative plaster
• Ready to use with no dilution required
• May help fill minor cracks, scratches and imperfections
• Waterproof and frost-resistant
• Can be reinforced with mesh where required

Substrate Preparation

All substrates must be clean, stable, dry and free from anything that could reduce adhesion. Substrate moisture content must not exceed 4%. Substrates should be durable, rigid, non-deformable and free from moisture. Concrete substrates should be free of release agents and formwork oils. If applying over a heated wall or floor, the substrate should have been heated beforehand and then left to cool for at least two days. Priming should begin after the walls and concrete elements have settled, shrunk and dried.

Product Preparation

PRO-601 FINO Contact Primer is supplied ready to use and does not require dilution.

• Stir thoroughly before use to ensure even distribution of the quartz aggregate
• Do not dilute with water or other solvents

Application

Where cracks, joints or minor imperfections are present, the primer may first be used locally as a filling or preliminary levelling coat. Once this has dried, apply the product evenly over the entire surface using a trowel or thick bristled brush, up to a thickness of 1mm. For improved reinforcement, embed fibreglass mesh into the wet primer immediately after application, keeping the mesh butt-jointed rather than overlapped. The surface may be sanded if required before applying microcement.

Application Conditions

Apply only when the air, substrate and material temperatures are between +15°C and +25°C. During drying, ensure good ventilation but protect the area from strong draughts that could cause overly rapid drying.
