Our water heater in the attic over our master bathroom leaked and we are having to patch a 3 x 3 ft. area with some new 1/2' drwall. Currently our ceilings have a texture that I can only describe as looking like veins and squiggles of plaster that were somehow applied to the ceiling. There is no descernable repeat in the pattern so I don't think it was rolled on. The squigles of plaster are 1/4-1/2 inch in with and almost resemble the patterns of ice crystals on your window in the winter. They are not very thick, only 1/8 inch or so and in places look like they were knocked down with a drywall tool or trowel.
I figure I will need to scrape off about 4 inches of the texture on the existing ceiling ajoining the new piece so as to float and tape but how the heck do I get this texture applied?
