LAYING RANGE / Waterproofing Bioscud Coloured, multi-purpose, elastomeric rainproof waterproofing protection for flat and pitched roofs, bituminous layers and external surfaces, resistant to UV light, atmospheric agents and standing water, ideal for use in GreenBuilding. Single-component, solvent-free, safeguards the health of both operators and the environment. Bioscud is easy to apply on large surfaces to ensure the waterproofing and the highly reflective protective decoration (Cool Roof) even of old, pre-shaped bituminous layers; it adapts to any shape, as to avoid overheating the rooms below. Certified for the encapsulation of fibre-cement and asbestos-cement slabs. PRODUCT STRENGTHS Bioscud -- Category: Organic Mineral products -- Waterproofing • Specifically intended for decorative rainproof waterproofing of flat roofs • Certified for highly reflective protective decoration – Cool Roof (white colour) of old pre-shaped bituminous layers as well • Certified for the encapsulation of fibre-cement and asbestos-cement sheets class A, B, C and D in accordance with Italian Ministerial Decree 20/08/99 • Water emulsion with a high level of elasticity for highly deformable substrates • Ready-to-use, water-based, solvent-free • Resistant to standing water, UV light and atmospheric agents, it does not need protection • It performs continuous waterproofing avoiding the discontinuity of pre-shaped layer systems GREENBUILDING RATING® No Solvent-free environmental hazard rating alth Care RATING SYSTEM ACCREDITED BY CERTIFICATION BODY SGS ECO NOTES --Water-based, limits the risk of loads that could be harmful and dangerous to the environment during storage and transportation --Improved on-site safety guaranteed Use -- Waterproofing in positive thrust of concrete and reinforced concrete structures and elements: coverings in general, flat and pitched roofs, floors, slabs. -- Waterproofing in positive thrust of walls, exterior foundation walls, foundations, plinths. -- Decorative, exposed waterproofing of chimneys, canopies, gutter channels, chimney flashings, roofing details, cornices, perimeter and containment walls, façades, lift shafts and stairwells, surfaces soundproofed with polyurethane foams for protection against UV rays (not soaked). -- Protection for humidity control of concrete and reinforced concrete structures (horizontal, vertical, inclined surfaces) with high protection from carbonation (low CO2 permeability). -- Repair and protective decoration Cool Roof (white colour) of old pre-shaped bituminous layers. -- Waterproofing of structures and elements under roofing tiles before fixing with polyurethane foam. -- Surfaces occasionally subject to foot traffic for maintenance work. Substrates: -- concrete and prefabricated reinforced concrete or fresh concrete castings -- mineral screeds from Keracem® Eco range and cement-based screeds -- cement plasters and cement-lime mortar -- old smooth and slated bituminous layers -- aluminium, steel, iron, copper, wooden floors -- Bioscud BT cured for at least 20 days -- floor and coverings featuring ceramic tiles, cement-based marble tiles, clinker, stone materials -- fibreglass after sanding down, fibre-cement slabs, external dry building systems -- old liquid acrylic-based sheaths and old aluminium-based varnishes after checking the adhesion with a peeling test -- PVC layers, after sanding down and preliminary test (reinforce with Bioscud TNT)

AREAS OF USE Do not use -- in case of unfavourable drying conditions or in case of impending rain -- in case of exposure to strong sunlight or on warm surfaces -- on floating or not perfectly anchored, damp, wet substrates or substrates subjected to rising damp -- on constantly trafficked surfaces, surfaces subject to heavy traffic or surfaces intended for glued heavy covering -- on lightened cement-based substrates not suitable to withstand direct loads, on insulating panels -- on old pre-shaped layers directly applied on insulating panels -- on light boards, wooden beads or canopies --...

Cement-based screeds: apply one coat of Bioscud diluted using water to 50% (coverage equal to ≈ 300 g/m2 not to be considered in the verification of the total weight to be applied). In the presence of fractionizing joints and/or cracks, carry out the mechanical excavation, remove dust and seal with Neutro Color; bond 20 cm-wide strips of Bioscud TNT with Bioscud near any joint and sealed crack. To avoid the swelling of the fabric in the presence of movements, bond the entire surface of the sheet on the back in contact with the surface of the screed; take care of the soft bonding of the...

COLOUR CHART white (RAL 9010) grey (RAL 7038) sand (RAL 1013) red (RAL 3013) green (RAL 6017) The shades shown are intended as an indication only. SPECIAL NOTES In climatic conditions of high humidity and/or low temperature drying times are lengthened, delaying foot traffic and significantly increasing the risk of being washed away in case of possible rainfall or in the presence of condensation. To decrease drying times, apply in several coats of max 0.5 kg/m2. In case of constant foot traffic, coat with Bioscud Traffic. For the treatment of absorbent surfaces, such as screeds and plasters,...
