G E N E R A L I N S TA L L AT I O N I N S T R U C T I O N S The following installation instructions are recommended by Amorim Cork Composites, but are not intended as a definitive project specification. They are presented in an attempt to be used with recommended installation procedures of the flooring manufacturers and screed. Room Conditions Temperature > -5ºC / Roommoisture content < 75%. Subfloor All subfloor work should be structurally sound, clear and level. The moisture content of the subfloor should not be more than 2.5% (CM) by weight measured on concrete subfloors.
