The crucial components of a spray gun.
Textures add an entirely new dimension to flat, smooth walls. Instead of a blank slate, y'all'll have a surface that will attract attending, add visual interest and warm the room with an earthy, organic feel. This technique also helps hide minor imperfections, making it a great mode to meld remodeled walls with existing ones—no small bonus to those of usa nonetheless perfecting our drywall-taping skills!
Applying a knockdown texture is an like shooting fish in a barrel, low-toll, depression-tech project that tin dramatically change a room's appearance and simplify wall repairs. The proper noun comes from i of the last steps in the project when yous employ a wide knife to knock down and flatten the peaks of the texture applied to the walls. This step gives the texture its stucco-like appearance. To texture the walls and ceiling of an average room, the rental sprayer, the joint compound and knockdown pocketknife will prepare y'all back simply most $lxx to $fourscore, and yous'll exist finished in ane solar day. These are the three components you lot'll use:
Joint chemical compound
To make this projection equally easy equally possible, use premixed all-purpose articulation compound. These buckets contain about 60 lbs. of "mud" and are bachelor at most home centers for $nine to $10 each. Don't employ the lightweight premixed compounds—you'll exist paying for a lot of air and the mix won't be as "sticky" equally the all-purpose. It generally takes one-i/2 to ii total buckets of mud to texture the walls and ceiling of an boilerplate size (12 x 12-ft.) room.
Knockdown knives
Traditionally, knockdown textures were washed with flat trowels or wide steel taping knives. However, the trowel technique is hard to principal. A much better choice is to use 1 of the flexible Lexan knockdown knives now available at drywall supply stores (see Photo 5). These knives are 18 to 24 in. wide and cost $15 to $18.
Acoustical sprayer and gun.
You'll need to rent an acoustical spray gun, hopper and compressor from a rental center or paint shop for this project. Although abode compressors work fine for the initial orangish peel glaze, they won't produce the volume of air you need for the heavier topcoat.
Look to pay $25 to $thirty for a one-mean solar day rental. While you're withal at the rental store, be sure to put the auto through a dry out run to exist sure it works. As well, remove the hopper from the gun and make sure the inside of the gun is clean. Look for a trigger adjustment on the gun It allows you to control the fluid flow. The recipes in this article volition give you the just-right mixes for your project.
Tips:
File whatever sharp edges off the blade mixer. Sharp edges will scrape lilliputian plastic curlicues off the side of the saucepan, bits that tin clog the gun or wind up on the wall.
You will get mud in places y'all didn't want it. Don't worry! It cleans upwards easily with a wet sponge.
CAUTION!
If you lot accept ceiling texture applied earlier 1980, information technology may contain asbestos. Earlier y'all remove any ceiling texture, contact your land'due south department of environmental protection, department of health, or a regional asbestos coordinator for information on asbestos testing and removal. For a list of regional contacts, click here. For general information on asbestos, click here.
Apply the texture
Photograph 1: Mask off everything you lot don't want textured
Mask your windows and doors with plastic sheeting. Then embrace remaining trim, outlets and light fixture bases (remove glass covers) with masking tape. Cover your floors with a heavy canvas or multiple layers of those bed sheets you haven't had the heart to go rid of. Don't use plastic sheeting on the flooring or your work area will become a skating rink.
Photograph 2: Add water to the joint compound and mix it
Thin the joint compound, or "mud," with water. Use a blade mixer mounted to a variable-speed 1/ii-in. drill (about mixers are too large for 3/8-in. drills). Y'all tin can too mix the mud by hand with a 5-gal. pigment stirring stick (available gratuitous at paint stores). Scoop one-half of a total saucepan of unthinned mud into an empty v-gal. bucket and add the correct corporeality of h2o to both buckets. Hug the bucket firmly with your feet and stir. After the initial stirring, scrape the sides and bottom with a stick or your hand and stir again. The second stirring helps remove thicker clumps that tin clog the spray gun.
Photo 3: Spray on the base coat
Spray an orange peel base coat on the walls and ceilings. This step will aid blend areas where new walls meet old, allow consequent drying for the topcoat, and human action as a background for the last texture. Hold the gun almost thirty to 36 in. from the surface. Starting in a corner, spray the ceiling kickoff, working in grids sized according to what you can comfortably attain from a stationary position. On the walls, piece of work from side to side and from top to bottom. Let the orange skin coat dry (three to eight hours).
Photo 4: Utilize the top coat
Employ the topping coat using the same techniques you used to spray on the base coat but with different gun settings and mud consistency. If possible, exercise in the closet or on a spare piece of drywall before moving to the main area. Hold the gun a fleck farther from the surface, up to 48 in. The splats should be 1/2 in. to 1-one/2 in. in diameter. End spraying the entire room before going to the "knockdown" pace. Afterward you apply the showtime coat, spray on a quick second glaze to help even out slight differences.
Photo five: Knock down the top coat
Knock downwards the topping glaze with an 18- or 24-in. Plexiglas knife and calorie-free pressure later the mud has set up for 10 to fifteen minutes. Start in the cupboard until you get the feel of the pocketknife and the consequence yous want. Knock it down in the same guild y'all practical it. On the ceiling, knock down in a direction across the joists or framing. This helps recoup for unevenness of the ceiling. On the walls, outset at the tiptop and bring the pocketknife two-thirds of the way downwardly, then start at the lesser and bring the pocketknife upwardly to finish off the knockdown.
Photos one to 5 show how to apply the knockdown texture.
Tip:
Don't let the hopper run dry out. Keeping at least 4 in. of mix in the hopper helps maintain a consistent menstruation.
Tip:
Always brand sure you first with a clean border on the knockdown pocketknife for each stroke. Proceed a damp sponge and a bucket of water handy for this task.
Dealing with textured ceilings
Scrape a textured ceiling with a drywall knife
Round the corners on a drywall pocketknife and use it to scrape the texture off acoustical or popcorn ceilings.
If y'all accept acoustical or popcorn ceiling texture, remove information technology by spraying it with h2o, letting it soak in for a minute, and and then carefully scraping it off with a drywall knife. Wear goggles and a cap. To minimize accidental gouging of the drywall, circular off the corners of the knife with metal snips and remove burrs with a shine-face file. If your ceiling texture has been painted, you won't be able to scrape it clean. Y'all may demand to skim-coat the surface.
Painting a textured surface
Paint a textured surface the mode y'all would new drywall. Let the "mud" dry completely. As it dries, information technology will release tremendous amounts of wet. You'll feel as if you lot're standing in an Iowa cornfield in July. If it's warm enough exterior, cut through the masking on your windows and open them, but leave the masking tape in place until the surface dries. If you take some box fans, apply them to help speed the drying.
Afterwards the walls and ceiling dry, check the surface for whatsoever spots you missed knocking downward or any ridges you raised with the corner of the knife. With 120-grit sandpaper and a sanding block, sand these loftier spots down. Brainstorm painting with a high-quality primer applied with a 3/8-in. nap paint roller. On the first glaze, avoid going over surfaces earlier they're completely dry. The mud is water soluble and painting too soon can cause you to pare upwards a thin layer of mud with the paint.
For the concluding paint coat, use a high quality latex paint and a 3/viii-in. nap roller. An "eggshell" or "satin" finish emphasizes the depth of the texture.
Other Knockdown Textures
If you desire to texture just a small area or a unmarried wall or don't want to mess with a sprayer, you have an endless supply of options. One of the simplest and virtually attractive is done with a plastic loop roller or ceiling texture roller, which fits on an ordinary paint roller. To practice this texture, use the same methods as described in this article except skip the spraying steps and curlicue on a single coat of mud. Yous tin too use a knockdown texture using texture paints.
