Mathys Pegafix

Mathys Pegafix

Mathys Pegafix is a colourless impregnating primer for porous, mineral substrates such as concrete, breeze block, bricks, etc. before painting them with waterborne paints.

Features & Benefits

• High fixing capacity
• Superior penetration characteristics
• Water based

Technical Data

• Density: 1,0
• Gloss Level: Gloss
• Gloss level at 60º: Glossy: > 80%
• Solids content in volume: 14 - 16 %
• Solids Content in weight: 14 - 16 %

Drying Times At 20°C/RH 50%

• Touch dry: 1 hour
• Dry to handle: 4 hours
• Dry to recoat: 2-4 hours
• Fully cured: 24 hours

Theoretical Consumption

• Very porous substrates (concrete, bricks): 5 - 10 m²/l. 
• Little porous substrates (plaster, porous paints for inside use): 15 - 20 m²/l

Practical Consumption

Practical coverage depends on many factors such as porosity and roughness of the substrate and material losses during application.

Surface Preparation

Remove dust and / or clean carefully. Blistering plaster has to be sanded slightly to ensure a good adhesion or an adhesion test has to be done in advance.

Directions For Use

To ensure homogeneity, coating materials should be thoroughly stirred prior to use

Application Conditions

> 5°C, < 90% R.H.

Application Methods

• Brush: Apply undiluted.
• Roller: Apply undiluted.
• Airless Spray: Nozzle: 11 - 15 / Pressure: 200 bars.
• Air-Atomised Spray: Apply undiluted.

Remarks

On low porosity substrates, Pegafix is preferred above Parafix and Porisol because of its better penetration characteristics. Possible dried spots (on windows, floors, etc.) can be removed with Thinner 22. When using on chalking substrates, always test for fixing suitability.
