DOES THE GRIT APPLIED WITH DIGITAL GLUES NEED A FINAL SURFACE FIXING?

However, in case of full field application (when the amount of grit can reach 600/800 grams per square meter), the glue is not able to bind the entire layer of grit.

For this reason it is necessary to fix the surface through a mixture of water and glue applied with spray.
It is also possible to add a quantity of glaze to the mixture in order to improve the fixing that takes place inside the ceramic oven.

In terms of process, the improvement happens when the organic phase starts combustion and the grit is not softened yet.

In all those cases in which the quantity of grit is lower (200/300 grams per square meter)  – or in case of decoration -, the water based digital glue is able to bind all the grit with no need of a surface fixing.

In any case, it is implied that, where possible, surface fixing is always recommended.
