I do repair work on drywall frequently where I need to match and blend the new patch into the existing wall. I've figured out many of the tricks but one that still gets me is when I get/have lumps in the texture.
After doing the repair/tape/float I have a completely smooth, dry repair that has mud lightly feathered into the existing texture. The float is usually 8"-12" wider than the actual patch and is then feathered to nothing using a wet terry cloth towel.
I've done enough patches to recognize the texture and determine the right consistency, pressure, nozzle size, etc to match the texture. Knockdown does still give me lots of trouble! but thankfully most houses around here are not knockdown. I start with pre-mixed mud in the bucket or box which usually needs to be thinned out. So I take some mud and mix it with water in another bucket. I'll mix for a few minutes until it looks smooth and usually let it set while I finish setting up the compressor, hose, etc.
I spray the patch and EVERY TIME small clumps of hard or thickened mud make it to the wall. Is there a step of filtering the mud before putting into the hopper that I'm missing? If so what do you use to filter it?
thanks
