Y 12 t0 24 hours 8 to 10 hours NOTE In the summer and winter months application must be avoided in times of extreme temperatures hot or cold For this reason it is recommended in winter months to apply product during mid day hours so substrate is as dry as possible and in summer months apply product early in the morning or late in the evening 16 Total cure time for the final surface Even though in most cases product is dry after 24 hours it is recommended to wait at least 7 days after application before covering with tiles or submitting the surface to intense traffic 4 CRITICAL POINTS See also Support preparation and drawings in Section 10 4 1 Edges Sharp and rouge edges should be removed or treated with Geomax between coats of IMPERMAX in order to avoid the membrane being punctured by these sharp edges 4 2 Surface joints At the joining areas between vertical and horizontal surfaces and in general before proceeding to application of IMPERMAX it is recommended to apply a first coating of IMPERMAX on the wall up to 20 cm and on the floor 10 cm Following this GEOMAX 30 cm should be laid while the product is liquid This will result in a seamless and continuous covering of this critical point Subsequent layers of IMPERMAX will then be applied 4 3 Expansion joints Expansion joints should be filled with an appropriate PU Sealant NEVER SILICONES or with IMPERMAX mineral fillers Calcium C
