Plaster, portland cement, and bonding to wood. How does it work?

As an artist, I'm experimenting with plaster and cement.As a resident of a temperate zone, I'm wondering about temperature, curing times, and bonding to substrate.I'm working on square pieces of particle board. I rough up the surface with a wire brush to improve bonding to the substrate.Both plaster and cement create heat as they solidify. Are either impaired by a low (and possibly sub-freezing) temperature? I have a makeshift oven that can reach 110 to 120 degrees (F) regardless of the outside temperature. Will heating cement or plaster to this extent improve its ability to bond to wood? Might it only reduce setting time?


hi we in the building industry use pva glue to coat surfaces for plaster plus adding it to the mix , if you are using finnish coat because of its smooth finnish , if you use a coating plaster it would adhere better but still use pva, cement is different, still use pva but it also crazes if used neat but suggest you use silver sand in the mix it is the smoothest sand and is used by artists in there work it is very fine grained, curing times will be shortened by heat but to much will crack or craze so better to heat a cupboard and store in there and not cook them, hth.

The British give this name to modern day cement. Ordinary Portland cement,sulphate resistant cement, white cement and Grey cement and so on. Most have chemical name but Portland is a patent name.

When putting them on wood you will need to use some method to let the material ooze through the board or it will fall off. That is why they used wood slats and chicken wire in the old houses to hold the plaster on the walls. As for curing times you can get quick set or use an admixture to set it up in colder weather. Good luck
