ON THERMAL INSULATION SYSTEM INSTALLATION TIPS In order to apply Brick Gres Generation to exterior walls with external insulation systems, we suggest installing the MAPETHERM® TILE SYSTEM external thermal insulation system after checking that the substrate is of sufficient strength and free of inconsistencies, and removing the existing paint. 1 Apply a coat of render with a minimum tensile strength of 1.00N/mm2 . 2 Fasten an aluminium starting profile with drip channel using nylon wall plugs with galvanised steel screws in order to ensure the insulation panels are installed perfectly horizontal. 3 Apply the insulation panels with a single-component cement mortar for panel application. The adhesive must be applied both to the panels and the substrate. 4 After a minimum of 48-72 hours have passed since the panels were applied, a structural render must be applied; this must have a high content of resins and synthetic fibres as well as good adhesion. For this thermal insulation system the use of PLANITOP HDM MAXI is strictly recommended. This substrate, once hardened, must provide a tough, compact layer which is impermeable to water and resistant to freeze-thaw cycles. 5 Apply alkali-resistant fibreglass mesh reinforcement, MAPEGRID G 120, to the mortar while still wet. Next, with the mortar still not hardened, 4-5 expansion plugs per m2 must be installed, with 7 mm diameter galvanised steel screws, for a fastening thickness of 160 mm, with 10 mm nylon plugs and thermal break, MAPETHERM TILE FIX, washers, fastened to the underlying structure. In the presence of openings, we recommend applying further portions of mesh arranged at 45° in the corners. 6 After at least 10 days’ curing of the structural render (in good weather), the ceramic covering can be laid using an adhesive with good deformability characteristics, such as the following, according to requirements (see technical characteristics at www.mapei.com): ULTRALITE S2, ULTRALITE FLEX, KERAFLEX MAXI S1. The tile adhesive must be applied both to the substrate and spread on the back of the tiles; the tiles must be adequately knocked and/or pressed down during application to avoid the formation of dangerous air bubbles. 7 Joints of a suitable width must be left when laying the tiles (10 mm). The joints may be grouted using keracolor gg, or alternatively ULTRACOLOR PLUS (see technical characteristics at www.mapei.com). 8 Flexible joints must also be created in correspondence with the string courses, limiting the sections to a maximum of 16 m2 . These joints can then be sealed with MAPESIL LM, neutral curing silicone sealant with maximum deformation of 25%, or alternatively using MAPESIL AC, mould-resistant pure acetic silicone sealant, for movements up to 25%, by first applying masking tape to the edges of the joint and then removing it once the silicone has been applied, before this is allowed to fully cure.
