Product: Homax Knockdown Aerosol Texture

(THD SKU 140875/Homax Item #4065-06)

Why do I have to shake the can?

You should shake the can hard a full minute before using and then stop to shake briefly every 15

seconds or so. The first shake is intended to move settled material off the bottom of the can and

break it up. Not shaking adequately may result in a clogged nozzle, poor spray pattern, or

excessively runny texture.

Shaking periodically during spraying helps recharge the pressure in the can and will help

maintain the spray pressure throughout the life of the can. Not spraying periodically during

spraying will result in weak spray delivery as the can is depleted.

Can I use this on the ceiling?

While the texture material is suitable for ceiling surfaces the spray nozzle is not configured for

spraying on ceiling surfaces. As the can is tipped to spray vertically, the pick-up tube inside the

can will eventually not be immersed in the texture liquid at the bottom of the can and it will only

spray gas. This will result in the propellant being depleted with texture remaining in the can.

Why does it spray with a slow or weak spray delivery?

Generally an aerosol knockdown texture will have a weaker spray than most other aerosols. This

is because it is designed not to atomize the contents, but rather spray a large splatter of material

on the surface. High pressure sprays break up the texture splatter too much. As long as the

texture will reach the wall surface with the desired splatter size, then it is spraying well.

There may be several other reasons for very weak or dribbling spray from the tip of the nozzle.

Most commonly, a weak spray (sprays only a few inches from the nozzle) is a result of the can

being sprayed at too cool of temperature. If the can itself is below 68 degrees, you may get a

poor spray delivery. If it is below 65 degrees, it will not likely spray well or at all, and you may

not get all the material out of the can. By simply warming up the can (This can be done by

running warm tap water over the can or placing it in a warm location for a period of time), it will

spray with a higher pressure spray.

Another reason for weak spray is failure to shake the can well prior to spraying or failure to

shake the can periodically while spraying. Shaking the can helps allow the propellant to build

pressure in the can as it is sprayed – this “recharges” the pressure in the can. As a rule of thumb,

for every 15 seconds of spraying time stop and shake the can about 10 shakes.

Why am I not getting the coverage I expect? One reason is that heavier texture applications or coarser textures will get lower coverage. If you are applying very heavy textures or multiple spray coats you can expect lower coverage than finer textures. In addition, when applying texture be sure to cover only approximately 80% of the surface. Applying more than 80% of the surface will result in less overall coverage and a less than desirable match.

When I move the drywall knife over the texture to “knock it down”, the texture flattens out – what am I doing wrong? It’s likely too much pressure is being applied with the knife. You want to hold the knife parallel to the wall with 2 fingers (thumb and forefinger) and just let it glide gently over the surface with virtually no pressure applied. The intent is to flatten the just tops of the liquid splatters on the surface but not flatten them completely out.
