What Kind Of Exterior Drywall Do You Use?

Regular Drywall is the most common type of drywall, suitable for walls and ceilings in most rooms. Thicker options like 5/8-inch or 3/4-inch offer enhanced durability, insulation, soundproofing, moisture resistance, and fire resistance for exterior walls. Foil-backed drywall is best for interior faces of exterior walls and ceilings, as it creates a stronger barrier from outside elements and can better insulate the home.

Purple board drywall is the most resistant to moisture and mold, making it suitable for use on the exterior of buildings. It is also highly fire-resistant, making it ideal for use in utility rooms, garages, and areas near a furnace. Type X Drywall for Garages is recommended for added insulation and sound barrier compared to 1/2″ drywall.

For painted surfaces, paper-faced, mold- and moisture-resistant gypsum board, such as XP Fire-Shield Gypsum Board, or glass-based drywall can be used. However, drywall and frost are a big problem, and it is not recommended where below freezing temperatures may last for hours or even days. Other variations of drywall include moisture-resistant drywall, mold-resistant drywall, fire-resistant drywall, soundproof drywall, and eco-friendly drywall.

In summary, various types of drywall, including regular, thicker, foil-backed, and fire-resistant, are available for various applications. To hang airtight drywall on exterior walls, caulk, adhesive, and foam seal are needed.

What is exterior drywall called?

Exterior Gypsum Sheathing is a water-resistant product used for attaching to exterior side-wall framing as an underlayment for various siding materials. It is made with a wax-treated, water-resistant core and water-repellent paper on both surfaces and long edges. Available in 1/2″ and 5/8″ thickness, it is suitable for fire-rated assemblies and contains no asbestos. American Gypsum’s gypsum wallboard is also available.

What is the best drywall for exterior walls?

Gypsum Sheathing is a drywall panel with a moisture-resistant core and glass-mat facers on both front and back surfaces and long edges. It is manufactured in various thicknesses and lengths, with the standard being ASTM C1177. Gypsum Sheathing is a cost-efficient exterior substrate in commercial construction and is increasingly popular in single-family construction due to its performance advantages.

Its specially treated core and glass mat facers provide a water and air infiltration barrier when applied as part of a home’s exterior wall assembly, and also protect the product during construction when periodic weather exposure can occur before the complete envelope enclosure. The popularity of Gypsum Sheathing is growing due to its cost-efficiency and performance advantages.

Can drywall joint compound be used outside?

Ready-mixed joint compound is not an appropriate material for exterior applications, as it lacks the capacity to treat joints in exterior gypsum ceiling boards. It is recommended that Sheetrock® Brand Setting-Type Joint Compounds (Durabond® and Easy Sand™) be used for this purpose.

What is waterproof drywall called?

Greenboard drywall is a water-resistant alternative to conventional drywall, offering better performance in damp or wet environments and increasing wall lifespan in moderately humid rooms. However, it doesn’t provide 100% waterproof results. If enough moisture is present, the sheet may still be damaged and need to be replaced. Trusscore Wall and CeilingBoard is the only drywall alternative that offers completely waterproof walls and ceiling performance. Both solutions improve the drywall sheet’s water or moisture resistance, but they may still need to be replaced if enough moisture is present.

Can you use drywall on the exterior?

The author discusses the use of drywall as an exterior siding material, arguing against the use of stucco, fiber cement, engineered wood, or vinyl. They suggest installing exterior rated drywall like Densglass, taped with joint compound and Fibafuse, and painted with a few coats of paint. The author also mentions using drywall for patio ceilings and walls, but questions whether they should go with stucco due to the difficulty in finding contractors for small projects and the author’s personal limitations in building a house. The author believes that using drywall is a more suitable option for their needs.

What material do you use for exterior walls?

Common exterior finishing materials include metal lath for portland cement, gypsum plaster, stucco, stone reinforcement, and ceramic tile. Expansion joints are used to attach parallel panels, allowing the final finish to naturally expand and contract without cracking. Drip flashing is used for stucco and stone veneer to allow moisture to escape the wall. Siding is the final layout on many buildings and comes in seven main types: Natural Stone Veneer, Vinyl/PVC, Fiber Cement, Composite, Brick, Wood, and Stucco.

Natural Stone Veneer is durable but heavy and expensive, while Vinyl/PVC is inexpensive and lightweight. Fiber Cement is durable but heavy and expensive, and Composite is engineered wood siding. Brick is low-maintenance but heavy and expensive, while Wood is durable but prone to pest and water damage.

Is there a difference between joint compound and drywall compound?

Joint compound, also known as drywall compound, is a white powder made from gypsum dust and water, used to create a paste-like texture on drywall. It is applied to create a seamless base for paint on walls and ceilings, effectively eliminating blemishes like fasteners, damage, or drywall tape. It is used to finish gypsum panel joints filled with paper or fiber joint tape, corner bead, trim, fasteners, and skim coat. It is also used for patching holes, bumps, tears, and minor damage to existing walls.

In North America, troweling joint mud on gypsum panels is a standard construction technique before painting. Joint compound type and formula selection form part of a drywall system, which can be finished from level 0 to level 5.

What kind of sheathing for exterior walls?

Plywood sheathing is a type of wood sheathing made from cross-laminated sheets, providing strength and stiffness for expansion and contraction. It is 15-19% lighter and has good moisture resistance. Oriented strand board (OSB) is a durable panel sheathing made from hundreds of thin wood strands hot pressed onto sheets with a wax and resin adhesive. OSB panels are dense and solid, with no soft spots, and do not breath or redistribute water as well as plywood.

OSB is often cheaper but has more volatile pricing. Waferboard sheathing is a manufactured product made by placing small pieces of wood scraps in a hydraulic press and gluing. Although cheaper, waferboard is weaker and less resistant to water.

Is there a waterproof joint compound?

CertainTeed M2Tech® 90 Moisture and Mold Resistant Setting Compound is a lightweight, sandable setting powder for drywall projects. It is ideal for prefilling joints, embedding joint tape, and concealing joints, fasteners, and trim accessories. M2Tech® 90 provides a robust fill with minimal shrinkage and sets in 90 minutes. Its moisture and mold-resistant properties make it an essential component for a complete M2Tech moisture and mold-resistant system. Available in convenient 8. 1 kg bags, this compound ensures a durable finish and is recommended for the finishing touches on drywall projects.

Will drywall last outside?

Dripboard, a hydroscopic material, can absorb moisture and should be stored indoors, ideally at a temperature below 125 degrees Fahrenheit. Gypsum board, a hydroscopic material, should not be exposed to high temperatures. The plastic shipping covering used for drywall during transit is not effective in protecting it from high-moisture environments, and may cause drywall to become stained, sag, or mold-prone. It is crucial to follow manufacturer recommendations for outdoor storage and remove the plastic cover when shipping drywall.
