Last time we talked about web and dry glazes. There are several forms of glazes; all at some point are wet.
As we noted last time, dry glazes (buff-off glazes, powder glazes, etc.) are sprayed on and once dry, after a minute or so, are buffed with a rag or Scotch-Brite to remove the dry powder off. Wet glazes are sprayed on or applied by brush or rag. Like staining a door, you wipe it on and wipe it off, leaving the glaze thicker in places you want it to show more.
Some glazes require a “vinyl sandwich." Vinyl sealer is applied before the glaze and then another coat is applied over the glaze. Vinyls are sticky and assist with adhesion as well as able to provide a barrier between the layer above and below.
Dry glazes are ready to clear coat as soon as you are done wiping the glaze.
Alkyd-based glazes require the clear coat to be applied within a certain window following glaze application. That’s because when they dry, they get quite hard and tough for the clear coat to hang onto them.
Those of you using a wiping stain for a glaze should never underestimate the power of prayer. Wiping stains, in my experience, are not meant to be used in an inter-coat application such as this. Serious adhesion issues are inevitable.
It is always a good idea to read your glazing instructions first and, if you can, talk with someone familiar with the glazing product.
Until next time…spray on!
