Here are few things to keep in mind when applying wallpaper: New Walls - Must be thoroughly cured, dry, primed and sized. Previously painted walls - Fill cracks or holes with patching paste, then sand smooth. Spot-prime the patches and size all walls to be papered. Walls with old wallcovering - Remove, patch, sand and clean. Be sure the old adhesive is gone and the walls are completely dry before sizing.
When you process wood in your shop, it is helpful to make notations on boards so you remember which have been cut to length or run through equipment like planers or jointers. Instead of using pencils for the notes, use chalk. Chalk lets you mark the wood without marring it so you can be more liberal with your notations. An inexpensive children’s sidewalk chalk set will provide several colors so that you can color-code your marking system.
