Instructions for use
The sides of the joint must be solid, clean and uniform. The dimensions of the seal must be a minimum of 6 x 6 mm and a maximum of 25 x 12.5 mm. For deep expansion joints, insert the sealing cord. AF 2.0 does not require a primer: on highly absorbent substrates, first apply AF 2.0 diluted with water using a brush. Cut the nozzle to a diameter proportional to the dimensions of the joint. Inject a generous amount of AF 2.0. Smooth it out with a spatula moistened with Smooth levelling compound before a surface film begins to form. Apply firm pressure to ensure the joint is filled without voids and that the sealant adheres completely to the sides of the joint.
Storage
Store in a dry place away from heat. It will keep for at least 18 months in its original packaging.
Warnings
- Not suitable for joints that are subject to foot traffic or constantly exposed to water.
- Do not apply to unpainted ferrous surfaces.
- Do not apply if there is a risk of rain.
- Do not store or apply at temperatures below 0 °C.
- Clean tools with water whilst AF 2.0 is still fresh; use mechanical methods and organic solvents once it has set.

For use on joints between building elements subject to low vertical and horizontal stresses, provided there is no persistent water pooling. Can be painted over after 20 minutes (a preliminary test is recommended). Excellent adhesion to porous substrates, even when damp: plasterboard, render, masonry, timber, fibre cement and concrete.
