Q: I wish to add loose fill insulation to my attic floor to supplement the insulation originally blown in by the builder 35 years ago. Since the original insulation never had a vapor barrier put down, will it be necessary to first remove the old insulation and lay down a moisture barrier before the new material is added?

A: I would advice putting a vapor barrier down under the old insulation before adding new material.

You should be able to do this by simply pushing the old insulation aside along one section at a time. Spread a polyethylene sheet against the surface to serve as a vapor barrier, then push the old insulation back in place over it. When you've done this over the entire attic floor, then go ahead and spread the new insulation on top.

Q: Can a competent home handyman do a satisfactory job of refinishing an old bathtub with epoxy paint?

A: I don't see why not - I know of several who have. However, you should remember that only a true two-part epoxy paint will stand up on a surface of this kind, so don't try to use a so-called epoxy spray or any other form of modified epoxy. Also, remember that preparation is extremely important if you don't want the epoxy to peel - and this means following the manufacturer's directions exactly, especially as regards cleaning and preparation of the old surface. The extra care in cleaning around the drain and next to the fixture - the alightals trace of soap curd or film will prevent proper [WORD ILLEGIBLE] And finally, remember this an epoxy paint is still a paint, so don't expect it to last forever, or to be able to take the kind of abuse that porcelain can.
