In order to attach a baseboard molding to drywall, follow the simple steps described below.

Step 1 – Preparing the Dry Wall

Before beginning, use the crowbar to pull away any previously installed moldings; this can be done by inserting the crow bar behind the moldings and exerting pressure to pry it away. Using the finishing material (chalk or plaster of Paris) fill out any holes and even out the surface. Once dry cope or even out the bumpy areas. Once that is done paint the drywall.

Step 2 – Preparing the Moldings

Pre-finish the baseboard moldings, this way you will save yourself the effort of having to bend down and paint the entire baseboard once installed. The holes left by nails can be filled up later on. Once the moldings are prepared saw down their lengths according to the measurements you took earlier. Using the miter box cut the edges so that two consecutive pieces fit perfectly at an angle.

Step 3 – Attaching the Baseboard Moldings

Place the prepared moldings against the drywall to make sure of their exact placements, always start with a hidden corner and move outwards. Then use glue to put them in place, this will ensure that the baseboards do not move when you hammer the nails in. Do not rush this process, and be extra careful when attaching the baseboards in angular regions. Once the baseboards have been attached use the finishing products to fill out the holes left by nails and the gaps at angles.
