Now the thoughts are on building a playhouse in loose timber. The goal is for it to look plastered. I saw that
http://www.minihusen.se/ has houses built from OSB that are just painted. If you mix some granulated material into the paint, the surface looks plastered.
Do you have any tips on how to do it if building according to your own OSB design? Should you reinforce with fiberglass strips somewhere, or would that create a strange texture? Should you use flexible sealant on the seams between the panels before painting? Which paint should you choose for the exterior? Where can I find the granular beads that give the plastered look? All tips are welcome.
