Frequently Asked Questions

Standard drying time is 24 hours per coat under ideal conditions, but high humidity or thick application can push that to 48 hours or longer. Setting-type (hot) mud cures chemically and can be ready in as little as 20 minutes.

Common thicknesses are 1/4-inch (curved walls), 3/8-inch (older homes), 1/2-inch (standard residential walls), and 5/8-inch (fire-rated, ceilings, garages adjacent to living spaces).

Screws are strongly preferred over nails because they resist nail pops as framing lumber dries and moves. Use coarse-thread screws for wood framing and fine-thread for metal studs.

Moisture-resistant drywall (greenboard) handles ambient humidity in bathrooms and laundry rooms but is not waterproof. Wet areas like shower surrounds require cement board or another true tile backer.

Finishing levels run from Level 0 (no finish) to Level 5 (full skim coat). Most residential work is finished to Level 4. Level 5 is required for high-gloss paint or walls under critical lighting.

Corner bead is applied to outside corners to protect edges and create a straight finishing line. Metal bead is fastened mechanically; paper-faced metal bead and vinyl bead embed in compound. Three coats of joint compound are feathered over the bead.

Panels are 4 feet wide. Lengths include 8, 10, 12, and 16 feet. Longer panels reduce seams. Hanging orientation affects where seams fall — plan panel layout to keep seams away from eye level.

Paper tape is embedded in a first coat of compound, followed by a fill coat and a finish coat, each feathered wider than the last. Paper tape properly embedded in wet compound produces a stronger, flatter seam than mesh tape.

Drywall primer-sealer (PVA primer) equalizes absorption between the paper face and joint compound so finish paint goes on uniformly. Skipping primer causes visible flashing even after multiple paint coats.

Press on the area with your thumb. Sound drywall is rigid. Soft, spongy, or flexing drywall is compromised and should be replaced. Damp gypsum supports mold growth inside wall cavities.

Common textures include orange peel (spray), knockdown (splattered and flattened), skip trowel (hand-applied), smooth (Level 5 finish), and popcorn/acoustic (older ceilings). Matching existing texture for repairs requires practice and the right equipment.

In most cases, no. Drywall repair and replacement is considered maintenance in Baton Rouge. Permits may be required if the work is part of a larger project involving electrical, plumbing, or HVAC.

In the Baton Rouge area, hang-and-finish drywall installation typically runs $2.00–$3.50 per square foot depending on finish level and project complexity. A site visit is the most reliable way to get an accurate estimate.
