Epifanes Polyurethane Primer
At a glance
- 2-component primer
- Available in all RAL-colours
- Quick-drying
Epifanes Polyurethane Primer is a tough modern two component Polyurethane primer for above the waterline. The primer provides a very smooth, pinhole-free base coat to then finish the surface with Epifanes Polyurethane Yacht Paint. This primer also fills small irregularities and pinholes, dries quickly and is easy to sand.
Primer on colour
A big advantage of Epifanes Polyurethane Primer is that the primer can be supplied in any desired colour. By priming the substrate in the right colour, the final topcoat will have a much better coverage, which saves considerable costs. Thanks to our Epifanes mixing machine, we can mix the primer directly for you in colour and ship it the same day.
Application of Epfinaes PU Primer
This primer is suitable as a pre-coat on bare polyester, existing polyurethane systems and over epoxy resins. Suitable for processing above the waterline.
Benefits of Epifanes Polyurethane Primer
- 2-component primer.
- Fills pinholes and small irregularities in the substrate.
- Very fast drying and easy to sand.
- Available in colour.
Directions for use
Follow the instructions below to apply the Epifanes Poly-urethane Primer correctly:
- Degrease the surface and remove any dust or grease.
- Mix the primer in a 4:1 ratio by weight.
- Let the primer react for 10 to 15 minutes.
- Apply the Epifanes primer with a 2K nylon roller. Roll systematically, do not apply too much pressure and do not apply the primer wet-on-wet. Lightly smooth the surface and use a brush for the corners. Always ensure sufficient ventilation during application and drying.
- Now let the primer harden for approximately 6 hours and sand the primer smooth with grit P240. The smoother the primer, the smoother the final coat.
You can now finish the surface with Epifanes Polyurethane yacht varnish.

Product properties
The key technical properties clearly listed in one place.
- Article number
- LAK002098
-
Gloss level indicates how much light a dry paint or coating reflects and how the finished surface looks.
- Matt: little reflection and a subdued appearance.
- Satin: a gentle sheen between matt and high gloss.
- High gloss: stronger reflections and a more pronounced colour, although surface imperfections may become more visible.
Gloss can be measured in gloss units (GU) at a specified angle. Terms such as matt and satin do not necessarily mean exactly the same thing across manufacturers. Substrate condition and application also affect the final appearance.
- Does not apply

The recommended layer thickness is the thickness at which you apply each coat of paint, coating or resin. It is usually given in micrometres (µm) or millimetres (mm).
- Wet film thickness: the thickness immediately after application.
- Dry film thickness: the thickness after drying or curing.
For a coating with 60% solids by volume, a wet film of 100 µm will theoretically produce a dry film of approximately 60 µm. Film thickness affects coverage, protection and drying. Always check whether the manufacturer specifies wet or dry film thickness.
- 80-120 µm wet (= 40-60 µm dry)
-
Density describes the mass of a material per unit volume. Values may be given in g/cm³, kg/L or kg/m³; 1 g/cm³ equals 1 kg/L. For example, one litre of a liquid with a density of 1.2 kg/L weighs approximately 1.2 kg. Density helps convert between weight and volume, but it can vary with temperature.
- 1.2-1.6 kg/dm³
-
Humidity during application is given as relative humidity, usually in percent (% RH). It indicates how much water vapour the air contains compared with the maximum it can hold at that temperature. Excessive humidity can interfere with drying or adhesion of some coatings. Also check that the substrate is dry enough and free from condensation.
- 50% - 75%
-
Mixing ratio indicates how much of each component is needed, for example resin (A) and hardener (B). A ratio of 100:50 by weight means 100 grams of A to 50 grams of B; by volume you might use millilitres. Weight and volume ratios are not necessarily the same because the components may have different densities. Accurate measuring is important for proper curing.
- 4:1 (by weight)
-
Minimum application temperature is the lowest temperature at which a product may be used according to the manufacturer. The limit can apply to the air, substrate and product itself.
At lower temperatures, resins and coatings can become thicker and cure more slowly. Moisture can also condense on a cold substrate and reduce adhesion. Check the dew point and measure the surface temperature before starting. A longer drying time does not automatically make application below the specified minimum acceptable.
- 15 °C
-
A paint or varnish layer is dust-dry when settling dust is less likely to stick to the surface. It may not yet be touch-dry, ready for overcoating or suitable for loading; these are different stages of drying and curing.
- 2 hours (20 °C)
-
Consumption or coverage describes how much product is needed for a given surface area. Consumption may be stated in g/m² or kg/m², while coverage is often given in m²/L or m²/kg. A consumption of 0.2 kg/m² means a theoretical 200 grams per square metre. Actual use depends on film thickness, substrate absorbency, application method and waste.
- 12 m²/kg
- Net contents
- 3 kg, 750 g
-
The application or processing methods specified by the manufacturer, such as brushing, rolling, spraying, casting or hand laminating. The chosen method can affect consumption, layer thickness and finish.
- Brush, Spray, Pile roller
-
Working time is the period during which a product remains workable after mixing or activation, usually given in minutes at a specified temperature, often 20 °C. With reactive resins, the chemical reaction also continues in the mixing container, and larger quantities or higher temperatures can shorten this time. Working time is different from gel time and full curing time.
- Approximately 180-240 minutes (at 20 °C)
-
VOC content (volatile organic compounds) indicates the amount of these substances in a product, usually expressed in g/L (grams per litre). They may evaporate during application and drying. The value describes the composition, but actual exposure also depends on how much is used, ventilation and the application method.
- 398 g/L
