Another hall we have completed is the one on Lipińskiego Street in Krakow. As with most large spaces exposed to airborne and impact noise generated by children, increasing acoustic absorption improves comfort in such a hall. Sonaspray plaster can be used in halls where there is a risk of ball impact, and even in swimming pools where humidity is high.

When spraying on trapezoidal sheet metal, remember that the final spray area will be larger due to the need to "spread" the sheet metal into flat square meters.
