It is a two-component epoxy varnish hardened with polyamide and for indoor application.
Fields of application
Applicable inside warehouses, indoor public parking lots, garage spaces. As a primer to seal pores and give greater performance to the finishing multiepox. As a varnish for greater protection of the applied color.
Properties
Glossy finish.
Great sealing power as a primer.
Good chemical resistance (see detail).
Very good mechanical resistance.
• Visible pot-life.
Concrete
Concrete often has, in the surface area, a layer of lime milk or is covered with cement that has low resistance and adhesion. We eliminate these layers with a milling or shot blasting machine. We clean all the remains and dust generated with plenty of water and subsequently allowing the surface to dry completely. We can also prepare the soil with salfumán diluted to 5%. We let it act for 3-5 minutes and rinse with plenty of water, let it dry for 24-48 hours before we can start painting. It is advisable, both on low and high porosity soils, to apply our multi-epox primer varnish to ensure anchoring, since it has the quality of a high penetration and sealing capacity of the concrete, facilitating the adhesion of the finishing layer. If the floor has few pores, a 50% dilution of the Varnish with our epoxy solvent is recommended to achieve high penetration and ensure anchoring. In soils with greater porosity, a 15% dilution is more than enough. Floors that have a phreatic humidity greater than 4% are not compatible to be painted. This moisture is not visible to the naked eye and exerts pressure on the surface that can tear off the layer of paint applied. If in doubt about the humidity of the soil, take a measurement with a hygrometer to verify if we exceed the limit.
Application
We do not recommend dividing the product to make partial mixtures. An inadequate mixing ratio would significantly affect the final performance of the epoxy paint. The two components will be mixed in the indicated proportions and homogenized if possible with mechanical stirring at low speed and dragging well along the walls to achieve the ideal mixture. Once the mixture is made and if the product is thick, that is when we will proceed to dilute it with epoxy solvent to achieve the appropriate fluidity for its application. It is recommended not to paint when temperatures below 10ºC and humidity above 75% are expected since they greatly slow down the curing of the epoxy paint, which can take weeks. The temperature must always be 3ºC above the dew temperature. We can apply it with a brush, roller and/or airless spray. For roller application we will use a short-haired thread roller. The dilution will be done with epoxy solvent and only with the amount necessary for its correct application. The dilution will vary depending on the application method and temperature and humidity conditions. The lower the temperature, the higher the viscosity and the greater the need for dilution.

Resistance summary:
After 7 days of action on the varnish film only show a decrease in the hardness of the pendulum of 50% of the starting hardness and no variation in the characteristics of the film. Conditioned resistance: Significant decreases have been found, but it is possible to withstand a load for a short time.
Not resistant: After a day of action they showed bubbles and swelling as well as a strong decrease in the hardness of the pendulum.
