Theoretical Consumption

Practical Consumption

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

Surface Preparation

Fill up deep holes with a filler or with a repair mortar (Pegacrete). Chalking substrates must be primed with Fixonal. Porous mineral substrates have to be pre-treated with Pegafix. Bare wood should be impregnated with Adex first. If you want to recoat with an acrylic paint, you should isolate the filled up parts with Porisol first.  If it is necessary to get a thick layer, you should apply several layers after hardening of the previous layer.

Directions For Use

Use a filling knife and apply thin layers.

Application Conditions

> 5°C, < 80% R.H. With water as long as Pegaflex has not dried; when dry clean with Thinner 22.


Pegaflex can easily be sanded wet, but not dry.
