CURIDAN

Preparation of the substrate:
Surface condition: It must be clean of dust, grease, paint residues, plaster and foreign bodies.
Substrate preparation: Loose or poorly adhered particles shall be removed, so it is recommended to clean the surface to be primed. If necessary, the surface should be levelled with a mortar which should be properly trowelled.
Type of substrate: CURIDAN should not be applied to polished surfaces as this may lead to adhesion failures.
Surface drying time: 3 to 6 hours, depending on humidity and temperature conditions. Check that the primer is dry to the touch.
Application tools: Can be applied by spray, brush, brush or roller.
Minimum application temperature: CURIDAN must not be installed when the temperature is below +5°C.

• Priming and preparation of porous surfaces where a bituminous film is to be subsequently welded. It can be used undiluted or diluted with water (10-20%), up to the desired concentration. Once the substrate is very dry, apply a coat of CURIDAN, making sure that the pores are well impregnated. The approximate coverage is 0.2-0.5 kg/m². In the case of bridges and parking decks, the coverage should be 0.2 kg/m². In bonded systems, the bituminous sheet is fully welded, so the entire surface must be primed. In non-bonded or floating systems, the bituminous sheet is only welded at singular points (parapets, drains, expansion joints, etc…), and these elements must be primed.
• Priming and preparation of porous surfaces that are subsequently to be waterproofed or treated with asphalt products. It can be used undiluted or diluted with water (10-20%), up to the desired concentration. Once the substrate is very dry, apply a coat of CURIDAN, taking care to impregnate the pores well. It may be necessary to apply a second coat depending on the state and absorbent power of the substrate. The approximate coverage is 0.3-0.5 kg/m².
• Surface protection against humidity of buried concrete structures in civil works without great demands (walls, fins and abutments, foundations, pipelines, etc…). Two coats of CURIDAN should be applied with an approximate total final coverage between the two coats of 0.5-0.75 kg/m² depending on the substrate. Before applying one coat, check that the previous coat is completely dry.
