Hi. I was referred to airkrete.com to get thermal / sound insulation for my existing home. I want to inject it into existing plaster and lathe walls, ceiling between basement apartment and main floor, and attic floor. My home is in Oakland CA and currently not insulated.
Is it possible to inject aircrete as DIY or with hired local labor or do I need to work with a company that soecializes in it like airkrete? I am happy to buy injection equipment if well executed DIY would produce similar results to hiring airkrete (in thermal insulation and sound insulation).
If it is possible to DIY, can you share links to required tools to effectively inject it and any instructions? In gratitude, Jeff
