Many different techniques are employed to give walls certain features. Paint or wallpaper are applied for aesthetics, insulation is applied behind for better energy efficiency for heating and cooling and texturing is carried out on the wall surfaces to either conceal a less than perfect taping job, or to enable better sound absorption.
Textured wallboard can easily be done onsite and there are a variety of effects to choose from, depending on the purpose. With the right tools and a little advice, a person can create textured wallboard with little experience in such tasks.
Popcorn is the name given to a fairly heavy texturing technique that is used to help muffle sound and is also used on ceilings. On the downside, it enables the retention of dust and dirt and is quite a difficult surface on which to apply paint. If your requirements for textured wallboard are to prevent noise from escaping, such as in a home theater room or sound studio, then popcorn is the finish to choose.
Knockdown or “Skiptrowel”
A textured wallboard done in the knockdown or skiptrowel style can also be of acoustic use and will also hide imperfections. Its aesthetic value is in giving an aged, rustic look to the room decor and is best described as stucco in the Spanish style.
Splatter or Orange Peel
As the name suggests, a textured wallboard with an orange peel look has been splattered with a fine overall spray and looks very similar to the skin of an orange.
Vary the Look
When creating textured wallboard, each of these applications can be applied in varying thicknesses and density to achieve the desired look and effect. Painting enhances the overall appearance and can help to apply greater visual depth depending on the colors used.
Most of the above textured wallboard finishes can be applied with a roller. The heavier ones such as a thick popcorn application may not achieve such uniform results but you will find there is much less mess from overspray.
Large surfaces of textured wallboard should be done using a drywall spray rig, which you can rent from a builders hire center. The rig is essentially a small air compressor and drywall hopper. Ready-mixed spray materials are available to purchase in dry form, to be mixed onsite.
