If you're going to paint again tomorrow, just wrap your brushes or rollers in plastic and set them aside in a cool place. If your painting chores are done, clean your tools thoroughly. Latex washes off tools and trays with warm water. Oil-based paint requires a thinner or mineral spirit. Wear plastic gloves and work the solvent into bristles or nap and rinse until the solvent is clear. Once dry, store brushes hanging bristles down in their original wrap or paper. Rollers should dry and store standing on end.
Whether you intend to install insulation yourself or hire a contractor, make sure that you know the guaranteed minimum R-value you are looking for. Have any contractor state that installed R-value as part of the bid. Also, prepare for the project by assessing what needs to be done to reduce air infiltration before installation. Include the cost of these added components and labor in your cost calculations. Keep in mind, too, that a tight home requires ventilation, so you may need to take another look at your bathroom and whole house ventilation strategies. Armed with all of this information, select the insulation that meets your energy efficiency, budgetary, and installation requirements. The end result will be a job well done, with energy and cost savings to tally long into the future.
