You really should do some research before you speak.
Master of Plaster has been around for more than 20 years. It has been used by large and small contractors,as well as homeowners without a single failure.
It has been used in historicaly significant buildings from small houses to historic theaters,and hotels as well as state and federal office buildings.
I don't appologize for reccomending it. It is the only product of its kind,and I am very proud of having invented it.
You might try sending for some literature before criticizing.
