DESMOFLEX® Epoxy Primer
Pioneering technology 2-component, water-based epoxy primer
DESMOFLEX® Epoxy Primer is the first part of the most complete DESMOFLEX® PU system, that was created by the latest research discoveries of THRAKON laboratories, to offer the ultimate and long-lasting waterproofing. DESMOFLEX® PU system produces a highly hydrophobic membrane that protects, seals and provides excellent UV resistance. The exclusive new generation “DESMOFLEX®” technology gives to the surfaces high whiteness, water vapor permeability, excellent thermal resistance and excellent adhesion for years.

DESMOFLEX® Epoxy Primer
Description
DESMOFLEX® Epoxy Primer is a transparent, water-based, rigid, two component epoxy primer. Used as a universal primer in waterproofing, sealing and floor coating applications on absorbent and non-absorbent surfaces. DESMOFLEX® Epoxy Primer cures by reaction (cross linking) of the two components. Also provides high tensile and impact strength.
Application Fields
- Mainly used as a primer for polyurethane waterproofing coatings, polyurethane joint sealants and polyurethane and epoxy floor coatings on absorbent and non-absorbent surfaces like: Power floated concrete, Metal (various), Asphalt, Bitumenfelts, Ceramic Tiles, Old Acryl-based coatings, Mosaics, Glass
- Ideal to moist concrete surfaces
- Used as a tack-coat between coating layers it intercoating time intervals are overstepped
Advantages
- Simple application (roller or brush)
- Low odor
- Excellent anchoring to absorbent and nonabsorbent surfaces
- Can be applied on moist surfaces, without loss of adhesion
- Resistant to stagnating water
- Can be diluted with water
- Provides high tensile and impact strength
- Heat and frost resistant
- Stops the creation of dust
- Chemical resistant
Application Steps
Careful surface preparation is essential for optimum finish and durability. The surface needs to be clean and sound, free of any contamination, which may harmfully affect the adhesion of the primer. Old coatings, dirt, fats, oils, organic substances and dust need to be removed by a grinding machine. Possible surface irregularities need to be smoothened. Any loose surface pieces and grinding dust need to be thoroughly removed. Do not use a metal-ball blasting machine to grind the surface, because the heavy metal-ball impacts destroy the cohesion of the concrete surface and lower its stability. New concrete structures must dry for at least 28 days.
Step 2DESMOFLEX EPOXY PRIMER Β and Component DESMOFLEX EPOXY PRIMER A should be mixed by low speed mechanical stirrer, according to the stipulated mixing ratio, for about 3-5 min. ATTENTION: The mixing of the components has to be affected very thoroughly, especially on the walls and bottom of the pail until the mixture becomes fully homogeneous.
Step 3Dilute mixture with 10-20% of clean water, to regulate viscosity. For best results, the temperature during application and cure should be between 5oC and 35oC. Low temperatures retard cure, while high temperature speeds up curing. High humidity may affect the final.
Step 4Apply the DESMOFLEX EPOXY PRIMER by roller or brush, until the surface is covered.
Step 5After approx. 6-12 hours and while the primer is still a bit tacky, apply the polyurethane coating DESMOFLEX PU.
Step 6RECOMMENDATION: Please ensure consumption within the Pot Life. Do not apply the product, at ambient and ground temperatures.
Storage
Pails should be stored in dry and cool rooms for up to 36 months. Protect the material against moisture and direct sunlight.
