Is paint considered building materials? And would new cabinet handle pulls be considered building materials?

For what purpose?

for my home renovations...I had kitchen cabinets painted and cabinet handle pulls installed.

Are you trying to deduct the sales taxes on these purchases?  What deduction are you wanting to claim for this expense?

yes for the sales tax

as part of building materials.

The IRS allows you to deduct sales taxes when you purchased and paid sales tax on the materials to build a home, build a substantial home addition, or perform a major home renovation.  Unless you did more than refurbish your kitchen cabinets, I doubt your purchases qualify.  But if these items were bought as part of a major kitchen remodeling, then, yes, they're clearly building materials.

Keep in mind that with the sales tax deduction, the IRS gives you a predetermined deduction to cover routine purchases.  The itemized sales tax deduction is only for major purchases of certain items.
