Well, this is tstex...your gunite walls have the staining and drip marks like mine, but I have brown scum on the bottom that is both in the water, the shore line where it is mushy and drying and dried-up where it has broken off in big pieces the size of potato chips [yum, yum].
I'll post some pic's too of both our pool and summer kitchen...the fire place was just built and soon the exterior stone will be added. We went w a real fire-brick interior and chimney was clay-flue...we are doing granite countertops, travertine versailles pattern in both the kitchen and decking [little over 1500sq ft for all]. we are adding 7 ft granite topped benches betw the Austin Stone fire place and austin stone columns - the base of the benches are austin stone too. the granite counter tops is 17' 10" long x 38"...lots of serving space w stainless steel sink and Echelon grill...can't wait to grill steaks and s-kobs...
Also, many thanks to all our Veterans of all wars and those people that have supported them in any and all capacities..w out you, we could not write so freely in these forums...
Regards,
tstex
