When placing Politerm® Blu screed over existing concrete slabs, concrete beam decks, compacted hardcore sub-base, etc: it can be done without using an electro welded mesh in the pour. If the receiving surface however comprises insulation boards, a bituminous and/or synthetic waterproofing layer, tiled floors, or corrugated steel sheet, etc., before pouring Politerm® Blu screed sheets of electro welded lath (minimum dimensions): wire ø 2 mm - mesh 50 x 50 mm) need to be included, appropriately tied and spaced from the laying surface.

Before apply the waterproof finish, it is necessary to prepare the surface using one of the two following methods:a. Abrade the surface using an electric sander fitted with an abrasive disk and dust extraction; alternativelyb.

For mixture with sand (density greater than 350 kg/m3), add 400 gr of additive each 50 kg of aggregate.

In case of laying surfaces composed of floors, cls castings, loose stone foundations, etc.. the application of the base screed prepared with Politerm® Blu doesn’t require the insertion of a galvanized mesh into the casting. In case of laying surfaces composed of insulating sheets, waterproofing synthetic layers, ceramic floors, linoleum floors, pvc, wood, moquette, corrugated sheets, etc.. before to laying of the base screed prepared with Politerm® Blu, it is necessary to lay the galvanized sheets (minimum size: wire ø 2 mm – diameter 50 x 50 mm), tied together and well-distanced from the laying surface.

Before the laying the Politerm® Blu screed, it is necessary to place sheets of galvanized mesh (min dimension of the cable diam. 2 mm, mesh dimension 50 x 50 mm), appropriately tied and spaced from the roof surface. This system makes the cast screed monolithic and assists the installer when working on sloping roofs.

Before apply the waterproof finish, it is necessary to prepare the surface using one of the two following methods:a. Abrade the surface using an electric sander fitted with an abrasive disk and dust extraction; alternativelyb. Melt the surface polystyrene beads polystyrene beads, using an LPG roofing gas torch.Neither method to be employed until 7 days after the screed has been laid.
