Cement-based substrates.

Any previous coating will need to be removed.

The support must be clean and free of foreign objects.

The substrate must be clean, dry, dust-free, free of oil, grease, surface laitance or other elements that impede adhesion such as old waterproofing membranes or other coatings.

The substrate shall be cohesive, without loose particles, with a regular surface texture.

In the case of concrete or mortar substrates, if there are cracks or fissures on the surface, these must first be repaired with DANOPRIMER® EP and DANOQUARTZ® SP 49.

Concrete roofs must be set for at least 28 days.

The joints between tiles can be filled with ELASTYDAN® PU 40.

Contaminated concrete surfaces shall be mechanically treated, either by sanding, diamond grinding, shot blasting or sandblasting, followed by vacuuming.

Do not apply on damp substrates or substrates subject to dampness under coating, dampness due to indirect, negative or hydrostatic pressures.

The support must be healthy, clean, flat, free of paint, crumbling or poorly adhered parts, release agents, etc. and in general without any substance or particle that may prevent correct adherence.

Before starting the application, check that the environmental and substrate conditions are suitable:

Temperature between +5ºC and +35ºC, and Relative humidity 75%).

Substrate temperature at least 3ºC above the Dew Point Temperature.

Pour component B into component A, and stir the 2 components for 3 minutes with a low speed mechanical mechanical stirrer at low speed (300 to 400 rpm), until a homogeneous mixture is obtained. After mixing, allow to stand for 1 to 2 minutes. allow to stand for 1 to 2 minutes.

If adding silica sand to the mixture, first mix components A and B, and only then add silica sand to the mixture. Never add water or any kind of solvent to the product.

Never add water or any kind of solvent to the product.

Sealing of concrete : Apply uniformly with brush, roller or rubber harrow, so that the layer is free of pores. On medium and high porosity substrates, apply a second coat.

Regularisation mortar: In case of very porous or uneven substrates, or to create a vapour barrier, apply with a trowel up to the required thickness, a second coat of primer, type DANOPRIMER® EP mixed with silica aggregate 0.063 mm-0.3 mm in a ratio of approximately 1:1, depending on the ambient temperature. Roll with a spiked roller to help level and remove air pockets.

Intermediate coat: Mix DANOPRIMER® EP with 0.063mm-0.3mm silica aggregate at a ratio of approximately 1:1.5 and apply with a notched trowel. Roll with a spiked roller to help level and remove air pockets. If necessary, with fresh DANOPRIMER® EP, sprinkle silica aggregate to saturation. Once dry, remove unbonded aggregate. unbonded aggregate.

Bonding bridge : Apply DANOPRIMER® EP by brush or roller in a thin, uniform coat over the entire surface. surface. Always apply new concrete, mortar or epoxy mortar over fresh, tacky DANOPRIMER® EP. tacky.

Metal/Steel : Apply DANOPRIMER® EP uniformly by roller or airless, so that the coating is pore-free, within 8 hours after sandblasting to avoid oxidation of the surface

Outdoors, to avoid surface defects (bubbles) due to rising water vapour from the concrete or mortar, it should be applied when the temperature is constant or decreasing.

Treatment of fissures is very important. Poor crack preparation can reduce the service life of the coating.

Do not dilute or add any components that may alter the characteristics of the product.

Protect from water dampness for the first 24 hours (20°C).

Keep the containers hermetically sealed and not exposed to extreme temperatures (store between 10°C and 30°C) for a period not exceeding 24 months. The last four digits of the batch number indicated on the label correspond to the product’s date of manufacture (month/year).
