Drywall Textures

The last step in finishing a drywall project usually involves texturing the surfaces. The texture serves three important purposes. The first benefit is to add interest to the wall; a decorative touch. Secondly, a perfectly smooth and flat wall is difficult to create and flaws can be very easy to spot. The texture breaks up lines and hides variations in the wall's surface. Thirdly, a textured wall will help hide damage caused by small dings and scratches that occur and will stand out on a smooth wall.

Application of the texture is fairly easy but it does require skill and practice. Some textures are sprayed on while others are applied by hand. Both sprayed and hand-applied textures can be applied and left as is or they can be gone over by hand for a more refined appearance. Hand applied textures will take more time and skill with additional cost.

Spray types

Knock Down (Skip Trowel)

This method will transform an Orange Peel texture by gently applying a wide drywall knife and drawing it across slightly dry compound flattens and spreads the texture. This is known as knocking down a texture.




Orange Peel

Orange peel texture is sprayed on with the use of a compressor. Joint compound is thinned but left thick enough that it will not run. The diameter of the spray nozzle and the distance the spray hopper is held away from the wall will affect the size of splatter and voids. This method is very quick to apply finish




Popcorn (Acoustic)

This texture is sprayed on with the use of a compressor. The first coat is applied using a thin coat with even strokes. Next additional coats of popcorn texture, if desired, will be applied allowing each coat to dry before spraying the next coat.




Hand finished

Crows Foot

A slightly thinned compound is applied with a roller. Next a large straight brush is dipped onto the wall and pulled straight away repeatedly to create a stippled effect. This method is fairly easy although time consuming. Another method allows this texture to be applied to your ceiling without rolling on the compound first.

Hand Troweled

With this method the compound is applied by hand with a drywall knife. This method is typically applied in arcs. This style can varied in many ways such as applying heavy coats with large arcing ridges, similar to Spanish stucco. Even and smooth with subtle tool marks and no voids, similar to a plaster finish. This finish takes more time and skill.

Mud Troweled

Compound is applied with the edge of your trowel alternating in vertical and horizontal swaths to create the desired design. Next a drywall knife will gently run a joint across the texture to flatten it a bit; this step constitutes the knockdown. The more pressure used, the flatter the resulting texture. Drawing the knife across the joint compound from at different heights and at different angles will create random patterns.



Drywall Cornering

Part of the finishing process with drywall is the installing of corner bead. This is a building material made from a thin strip of vinyl or aluminum that is bent at a 90 degree angle. This material is available in standard lengths ranging from eight to twelve feet.

Drywall Size, Thicknesses and Types

Half-inch drywall panels are the standard thickness for interior walls. For ceilings you will want to use half-inch or even go up to 5/8? inch thick panels to prevent sagging.

When creating various arch designs or working with other curved surfaces a thinner type of drywall is available in one-quarter inch thick. This drywall is valuable with partial arch, full arch, eyebrow arch, step arch and many more applications. Pentoir Inc. will provide trained and experienced installers to insure that every project meets the satisfaction of its customer.

Thicker applications are needed; five-eight inch drywall is doubled. This is often referred as ?fire resistant drywall.? Depending on your local building code, some rooms such as those adjacent to garages are required to have fire resistant drywall.

The standard and most common size of drywall is 4 feet by 12 feet. However 16 foot lengths are available for higher ceiling such as cathedral type. This allows for a completely unbroken surface from floor to ceiling.

Half-inch drywall panels are the standard thickness for interior walls. For ceilings you will want to use half-inch or even go up to 5/8" inch thick panels to prevent sagging.

Types of Drywall


Standard drywall. Sheets butt against each other and should be plastered over. Uses include: Walls and ceilings to be plastered


Regular drywall with a tapered end that allows for easier filling between gaps with joint compounds. Uses include: Finishing walls


Core is impregnated with waterproofing materials, but is breathable so the surface beneath the board can "breathe" through the wall's surface. Can be used in areas of high water usage — as abase for tiles in a shower stall, for example. Uses include: Bathrooms and kitchens


Has vapor-resistant paper on one side, so is less protected than moisture-resistant sheets. Has a silver foil-like layer on non-decorative side. Uses include: Used in cold climates; not for moisture-resistant materials or humid climates


Has greater fireproofing qualities than standard drywall. Uses include: Integral garage ceilings, some corridors, stairwells


A polystyrene layer bonded to the non-decorative side provides greater heat insulation than normal. Thicker than other drywalls. Uses include: Garages


Has greater soundproofing qualities than other drywalls. Uses include: Walls and ceilings in apartments or condos

Cement board

Not a drywall, but has similar properties and uses. Is a strong, moisture-resistant base board, often used as a subfloor, beneath ceramic tiles or as a backing for wall tiles. Board thicknesses and sizes vary. Uses include: Can be used as a subfloor beneath ceramic tiles, or as a backing for wall tiles

Chinese Drywall. What is it and can it affect YOU!

From 2004 through 2006 there was a shortage of American made drywall due to the increase in building after hurricane Katrina and other storms. Many American suppliers imported there drywall from a German-based company, Knauf Tianjin, which has subsidiaries in China. This drywall was manufactured from waste materials found on scrubbers within coal-fired power plants. This material appears to contain carbonyl sulfide, sulfur dioxide (SO2), and carbon disulfide (CS2), iron sulfide (FeS2 pyrite), hydrogen sulfide (H2S). Some believe that high humidity will create a noxious odor and can cause damage to copper materials found in wiring and piping. This damage can result in a shorter life span of such material and could cause failure in certain equipment such as air conditioning units. Many lawsuits are pending with the use of Chinese drywall. PENTOIR INC. HAS NEVER PURCHASED, SUPPLIED, NOR INSTALLED CHINESE DRYWALL. Pentoir Inc. will remove and dispose any Chinese drywall from your home or place of business. We will replace this drywall with the proper materials and return your home or business to its original state. Please call or e-mail us for an appointment and estimate.
