Hi. I’m an oil painter considering using KILZ 2, (latex water-based primer, sealer and stain blocker composed of Titanium dioxide, Nepheline Syenite, Limestone) as a sealer for maple panels. I will use 4 or more coats of acrylic gesso (either Golden or Art Board) after the KILZ. I hear that KILZ is a good seal for panels but also know that industrial grade materials aren’t always tested/recommended if the intention is to build an archival surface. Do you recommend KILZ or should I stick with GAC 100? Thank you.
Thank you for the quick response!
We have to be honest here and say that we have no idea if this is a material that would be considered permanent as a sealer/sizing coat. It may be great, but it is neither made, nor tested for this purpose. I would stick with GAC 100 or 400 to be safe. I would personally use GAC 400 on panels, as it is less gummy and more rigid.
Most of the Kilz water-borne products are made using styrenated acrylic copolymer, not 100% acrylic dispersion base. In architectural coatings, this is usually for sake of economy, as the generally better performing 100% acrylic is more costly. Also, house paints are made using plasticizers and coalescents that would not normally be used in artists’ painting grounds.
