Guide to Drywall and Painting Tools

This page contains a guide to drywall repair and painting tools. We refer to these in many of the articles on this website, this information is provided for visitors unfamiliar with these tools.

tub of ready-mixed joint compound

Ready-mixed Joint Compound

Ready-mixed compound is a premixed mud used mostly for finishing drywall seams but it's also well suited for repairing minor damage to drywall and plaster surfaces. It is very soft and extremely easy to sand. In fact, a small patch of dry ready-mixed compound, such as over a nail pop, can be remove completely in just a few strokes of 120 grit sandpaper. This can be a problem when you remove more of the patch than you need to and have to redo the repair to smooth out the wall again.

bag of setting-type joint compound

Setting-type Joint Compound

Setting-type joint compound comes as a fine powder, it is very well suited for making thick applications for deep wall damage. This compound is similar to concrete in that it sets after mixing with water due to a chemical reaction rather than drying from evaporation like ready-mixed does. Because of this, setting-type can be much harder to sand than ready-mixed joint compound. To make sanding easier the manufacturers came up with softer formulas, Easy Sand Durabond® is one of these. While this newer product is easier to sand than the original it is not as versatile. Don't for instance, try to skim coat with Easy Sand Durabond, it tends to curl up and fails to bond well when applied in very thin coats. Because of this, we don't recommend these softer setting compounds. Instead we suggest applying regular setting compound in thin coats to make it easier to sand.

open and finished drywall edges two drywall sheets butted together

Drywall Sheets

Drywall sheets consist of a gypsum core, sandwiched between two sheets of heavy paper. The paper is wrapped around the gypsum on two sides to form finished edges.

Drywall sheets are commonly available in 4ft x 8ft and 4ft x 12ft pieces with thicknesses of 1|4, 3|8, 1|2 and 5|8 inches. Drywall available at your local home store includes three basic types: standard, fire retardant and moisture resistant drywall. Some building codes require fire retardant drywall on ceilings and moisture resistant is used in bathrooms and kitchens to standup to the high humidity in these rooms.

The finished edges on the sheets are compressed, so when two pieces are placed, finished-edge to finished-edge, a small depression is formed. The seams between the sheets are taped and the depression is filled with joint compound to create a flat, smooth, finished surface.

drywall joint knives and mud pan

Drywall Finishing Tools

Tools for applying drywall joint compound include a mud pan and joint knife. Mud pans are available in plastic and stainless steel. The metal pan is the best choice for keeping the knife blade clean and controlling the mud. Plastic pans have a metal strip embedded in the rim that can easily become clogged and it tends to fall out and rust.

Joint knives are available with varying flexibility. A medium flexible blade is the best choice for drywall work. If the blade is too flexible, it can bow when finishing seams, causing a dip in the finished joints. If the blade is too stiff it can be impossible to smooth the surface of the mud when skimming.

drywall joint tape and corner bead

Drywall Joint Tape and Corner Bead

Flat drywall seams can be finished with paper tape or self-sticking, fiberglass-mesh tape. Paper tape should be applied with plenty of joint compound and stuck down tightly or it will come free easily. The mesh tape can be easier to use and it usually requires fewer coats of mud to finish a seam. The mesh should be lightly sanded after the first coat of joint compound to knock down the fibers and make the joint easier to smooth out. Outside drywall corners can be finished with metal or paper drywall corner bead. Metal corner bead is the best choice in most cases for a square, durable corner.

handling joint compound for finishing drywall seams

Using Joint Compound

It's best to use ready-mixed compound for finishing drywall seams and inside corners, setting-type will harden too quickly in most cases, causing problems. Exceptions to this are finishing butt joints and metal corner bead, where a thick first coat is required. In these cases, setting compound will not shrink like ready-mixed and it is much harder when set, making for a more durable joint.

Use a small joint knife of about 6 inches for the first coat or two of joint compound on seams and inside drywall corners. A larger knife can be a good choice when first coating metal corner bead and for the finish coat on flat seams and inside corners.

To handle and apply mud, scoop some into a mud pan and collect a portion onto the rim. From the rim, work the mud onto the wall, a little at a time to get good coverage. See Skim Coating Techniques for more on handling joint compound.
