Jo Sonja 250ml All Purpose Sealer

Jo Sonja's All Purpose Sealer is a surface 'primer' and will seal a wide variety of items in preparation for painting. Pre-priming with All Purpose Sealer or Gesso will ensure good paint adhesion and will prevent moisture loss into absorbent surfaces.

All Purpose Sealer can be used in replacement of Gesso on items that require sealing without 'tooth' or opaque colour.

Suitable items for sealing include; wood, MDF, cardboard, paper, canvas, metal, unglazed bisque and terracotta (it is best to test for suitable adhesion on unusual surfaces).

All-Purpose Sealer will assist adhesion to some plastics, soaps and wide candles where flames will not come in contact with the design.

A light sanding is recommended to promote the adhesion of paint to any of these surfaces. 

Jo Sonja All Purpose Sealer makes an excellent glue to adhere decoupage, gift wrap, or fabric to wood and other surfaces.

Note: All Purpose Sealer is a primer or sealer, not a finishing varnish. If used as a varnish it may become tacky in warm weather and cause surfaces to stick together.
