We've been doing plaster repair and skim coating for a long time, and our process and the materials we used has evolved over the years. One of the biggest challenges in skim coating over lime plaster that's been painted or patched has been ensuring a base coat adhesion when beginning to skim. Recently we've used Structolite over a surface that's been covered with PlasterWeld. This process took a good deal longer in order to apply the PlasterWeld, and the plaster being applied was the gypsum based Structolite.
We started using Takcoat from LimeWorks.us as an alternative base coat. This plaster is an Natural Hydraulic Lime (NHL) plaster that's been formulated to promote adhesion without the need for a bonding agent. It's not a high build plaster but provides a good first layer when doing a skimcoat application.
We'll do a 3 coat process.
1. Ecologic Takcoat
2. Ecologic TopCoat G or Master of Plaster Restoration Base Coat
3. Finish coat with Slaked Lime Putty
