Protective and decorative painting of concrete floors, restoration of the color of old resin floors, glazing of wall skirting boards, etc. Ideal for mechanical workshops, manufacturing industries, warehouses and factories in general where high chemical and mechanical resistance is required. It can be used both indoors and outdoors.
Concrete
The surfaces to be coated must be stable, clean and free of substances that could affect the adhesion of the coating. In case of restoration, use suitable mortars and products suitable for the system beforehand. Wait for the drying times before applying the next coat. The tensile strength must not be less than 1.5 N/mm². Existing paints, coatings or paints, cement grout residues, release agents, oils, greases, silicones, etc. they can be removed mechanically by sandblasting, blasting, hydroblasting or chemical removal.
Cracks and fissures
In case of static cracks, use Syntech Primer EP-W for sealing. The sealing of dynamic cracks or cracks larger than 4-5 mm must be assessed on site. Generally they can be grouted with elastomeric materials or act as expansion joints.
Grouting and spot repairs
Any holes or repairs to portions of concrete can be made with mortars from the REPAR line or by applying epoxy mortar made with Syntech Primer EP-W and quartz mastics. Apply a coat of Syntech Primer EP-W as a bonding primer, then proceed to seal and repair the damaged and broken concrete by applying the epoxy mortar. Any small filling of holes and cracks can be done by applying Syntech AS 21 epoxy mortar.
Resin coatings
The surfaces to be covered must be stable, clean and free of substances such as dirt, grease, oil, etc. which can affect the adhesion of the coating. Smooth the surface by mechanical sanding with diamond discs and vacuum. It is recommended to wash the surfaces and let them dry completely before applying the finish.
Primer for concrete
Syntech Pavicrom SBV can be applied directly to cementitious substrates as the product diluted with a maximum of 25% by weight of clean water acts as an anchoring primer.
Resin coatings
The application of Syntech Pavicrom SBV on resinous and multilayer systems must always be preceded by sanding the entire surface to promote and guarantee optimal adhesion of the product to the support.
Combine the two components in the indicated mixing ratio. Add component B (hardener) to component A (base) and mix well until a completely homogeneous product is obtained. It is advisable to start mixing briefly with an electric drill at low speed and then intensify the stirring up to a maximum of 300-400 rpm.
Leave the emulsion obtained to rest in the container, respecting the following induction times:
at 15°C ~ 20 minutes
at 25°C ~ 15 minutes
at 30°C ~ 10 minutes
The product can be applied uniformly using a spray gun or short-haired roller to avoid accumulations of material which could give rise to aesthetic defects. The application of the product must be carried out by crossing the passes and paying particular attention to the shots, regularly unloading the roller beyond the applied area to obtain a uniform film and eliminate any accumulations of product. Apply the first coat of Syntech Pavicrom SBV diluted with a maximum of 25% by weight of clean water as primer. The dilution must be carried out under mechanical stirring, adding the necessary quantity of water at the end of the induction time. Do not dilute the product further during application if it thickens it means that the use time has expired. Create a new emulsion with highly mixed material. Wait at least 12 hours, then apply the second one
Colored finish diluted with a maximum of 20% weight of clean water, respecting the consumption and thicknesses indicated. It is possible to create non-slip finishes by adding quartz or hollow glass spheres.
