DOREPOX FLOOR PRIMER
DEFINITION
Two component, solvent based epoxy varnish.
ADVANTAGES
• It does not contain fillers and pigments.
• Due to its low viscosity, it easily penetrates the capillary spaces.
• Forms a hard film.
• The film surface is shiny and slippery and prevents water and oil permeability.
• Easy to clean.
• It provides convenience in application as it has a long pot life.

APPLICATION PROCEDURE SURFACE PREPARATION
New concrete and cement plaster must be type C25 or a minimum dose of 350 and the plaster must cure for at least 21 days. The breaking strength of the ground concrete should be minimum 1.5 N/mm² and the floor temperature should be minimum +10˚C.
The floor temperature should be kept constant at least +3 ˚C above the dew point, preferably at a minimum of +8˚C. Old paint, dirt, dust, etc. on the old concrete and cement plaster surface. loose particles such as sandblasting, scraping, brushing are removed.
Oil and grease residues are cleaned with detergent water, if neutralization is required, the surface is wiped with 3-4% hydrochloric acid or acetic acid solution and washed with a water jet and rinsed. The surface is dried with an industrial vacuum machine.
Before applying the primer, care should be taken that the floor is completely dry. Concretes, mosaic and tile surfaces with high gloss and non-absorbent cement ratio should be roughened by light sandblasting or pickling.
It is applied to metal surfaces after they are cleaned from oil, dirt and rust by mechanical or chemical means.
MIXING
It is produced in ready-to-use sets according to mixing ratios. Care should be taken to ensure that the material temperatures are at MINIMUM +15˚C before application.
A component is mixed with an industrial mixer at 300-400 rpm with a suitable mixing tip and B Hardener component is added and mixing is continued.
It is necessary to ensure that the A and B components are mixed very well at the wall and bottom points of the container and the mixture is homogeneous. Otherwise, after application, unmixed A or B components may form a soft sticky film on the surface and cause an incorrect application.
An important point to note here is that the mixer tip touches the bottom of the container. This will minimize the entry of air into the mixture and will provide a healthier, problem-free surface.
The mixture is then transferred to another clean container and mixed for another 2-3 minutes. Material should not be prepared more than the amount that can be applied during the pot life.
MIXING RATIOS
DOREPOX PRIMER 2 parts A component 1 part B component
APPLICATION METHODS
By brush or roller. After drying, the film should be applied in one or more layers until a homogeneous glossy film is left on the surface.
CONSUMPTION
Theoretically, it has an average consumption of 3-5 m2/kg (depending on the roughness of the surface) in 2-3 coats.
WAITING TIME BETWEEN FLOORS
14-16 hours at 20˚C between layers of DOREPOX PRIMER, minimum 24 hours maximum 48 hours for topcoats.
MATTERS TO BE CONSIDERED
*Application should not be made at temperatures above +35˚C or below +10˚C, in rainy and windy weather.
Since low temperature will increase the viscosity of the material and affect the spread of the product on the floor, it prevents the formation of a smooth surface and makes it difficult for the trapped air bubbles to come out of the surface. High temperatures shorten the product stay in the container, making application difficult.
Windy weather affects a homogeneous surface spread, causing the ground to appear wavy depending on the air flow.
*Application materials should be brought to the application area 1-2 days before and their adaptation to the environmental conditions should be ensured to the maximum extent.
* In applications to be made in cold weather, the ground, material and ambient temperature must be ensured by bringing them to the application conditions, otherwise it should be taken into account that the application will create problems in spreading, drying and creating a homogeneous coating surface.
*Two or more component products such as epoxy or polyurethane must be applied by professional, experienced application teams.
*Epoxy resin and polyamide/polyamine etc. systems such as chemical curing systems. Reaction times are directly affected by environmental conditions, as there are no systems that dry out by air oxidation or volatile components, such as water-based acrylic polymers or alkyd systems that have been polymerized.
Low temperatures prolong the reaction time and reduce the fluidity of the material. Therefore, diffusion difficulties and consumption increases are observed. High temperatures increase the spreading rate and provide more homogeneity, but since the chemical reaction takes place faster, it requires an experienced application.
*A finished coating must be protected from water contact for at least 24 hours. Sudden temperature drops cause the application surface to become dull and have a stained appearance.
