Preparation & Application

Preparation

Ensure that the surface is clean and sound.

Ensure that the surface is free from grease or other contamination.

Mixing

Shake the bottle and then pre-dilute weber AD250 as recommended below, before use.

Application

As an admixture where movement is expected: use weber AD250 un-diluted and mix with the powder as recommended on the bag, but note that the mixing ratio may change slightly.

As an admixture for bonding onto impervious tiles or substrates: predilute one part weber AD250 with two parts of clean water, and then mix with the powder.

As a primer for porous or dusty substrates: pre-dilute one part weber AD250 with two parts of clean water, and then apply to the surface with a brush, sponge or roller.

As a sealer for gypsum based surfaces (e.g. plaster) prior to the application of a cementitious adhesive: pre-dilute one part weber AD250 with one part of clean water, and then apply to the surface with a brush, sponge or roller, making sure that the surface is fully covered. For very porous surfaces a second coat may be required.
