Knockdown ceiling repair
I have a water-damaged spot on my ceiling I need to repair. The original drywall texture is what we call knockdown here. Basically it's a stippled ceiling texture that is flattened by dragging a wide drywall knife over it after it's stippled. I have replaced and flattened the area, and plan to duplicate the stipple pattern with drywall topping compound applied with a paintbrush. I plan to, as best I can, connect the new stipple 'lines' to the surrounding undamaged areas 'lines'. I haven't been very successfull with this in the past and wonder if there is anyone with skill in this that is willing to give me some tips. Thanks in advance! -halfwit Originally Posted by halfwit I have a water-damaged spot on my ceiling I need to repair. The original drywall texture is what we call knockdown here.

Thanks in advance! -halfwit If it's true knockdown texture, you can buy aerosol cans that you can use to spray on the texture. By adjusting the nozzle, you can get the desired pattern. I usually spray over the existing texture all around the bare spot, in order to make it blend in. It can be a mess if you're spraying in a small area (such as a hallway), so tape and protect the walls accordingly, and always use a drop cloth. Good luck. The best way to retexture is to apply it like it was originally - sprayed with a hopper. Not always practical for small repairs - can be mighty messy. I had a roof leak in my living rm shortly after all the drywall [and carpet] was finished. I textured it with a brush and knocked it down. I'm not totally happy with the results BUT it beat completely covering the room [walls too] and once painted, although I always notice it no one else really does. I've never used any of the aerosol cans of texture so I won't comment on that. Originally Posted by marksr The best way to retexture is to apply it like it was originally - sprayed with a hopper.

I've never used any of the aerosol cans of texture so I won't comment on that. The aerosol cans are more of a mess then a hopper. The cans are not really made to be sprayed at the angle, so you end up spraying a lot on adjacent walls. Thanks, guys, I wasn't clear enough, but it's a different type of knockdown from what you're thinking. They roll on a thin layer of topping over a finished and sanded ceiling, then stomp it with a circular horsehair brush in an alternating round pattern. After it dries slightly they drag a wide knife over it. The area is 18 x 22, I replaced the drywall, sanded the surrounding texture down to the drywall paper for about an inch, then put on mesh tape with a thin layer of setting type drywall compund. When it dried I put on topping and dragged it flat with an 18 straight board. With a little touchup and sanding this should become flush with the original untextured ceiling. I plan to duplicate the surrounding pattern with topping and an angled paintbrush, then drag a 24 inch straightedge across the area, using the surrounding undamaged texture as a drag guide. This whole process should make the low spots and the flat spots equivalent to the surrounding texture. While cutting out the damage I noticed a previous repair (mesh and backing boards and screws) that was invisible and that made me envious. I hope I can duplicate that guys results with my methods, as I have raking light from windows behind the repair area. Thanks and wish me luck! -halfwit Those small cans don't work. For best results go with a hopper and compressor.
