Can I paint or stain Microllam, Parallam & Timberstrand?

Yes. If a wax overlay is present the surface should be sanded. Parallam Plus (Wolmanized) can also be painted or stained (see question 13 on page 11 of the Parallam Plus Specifier's Guide for more information). For a more aesthetically pleasing finished interior look, Parallam can be sanded and stained/ varnished.
