Product description
Hempel Light Primer is a high-quality 2-component epoxy primer. This high build primer prevents and repairs osmosis damage in polyester boats and also protects against general corrosion.
Light Primer is suitable for boats made from polyester, steel, aluminum and laminated wood. You can use this epoxy primer both above and below the waterline.
Benefits of Hempel Light Primer
- High-quality epoxy primer.
- Excellent impact and corrosion resistance.
- Excellent water resistance.
- Suitable for polyester, wood, steel and aluminium.
Directions for use
Hempel Light Primer is easy to apply with a brush, roller, spray gun or paint pad. The minimum processing temperature is 5°C. Avoid working in direct sunlight.
- Always ensure that the surface is lightly sanded, clean, grease-free and dry before applying Hempel primer.
- Stir the contents well before use.
- Apply Hempel Light Primer.
- Uncoated surfaces (below the waterline) - pre-treat porous surfaces with a first coat diluted with Thinner 845 (max. 20%). Then apply 3-5 coats to obtain full film thickness. If necessary, add thinner to aid application (max. 5%).
- Uncoated surfaces (above the waterline) - pre-treat porous surfaces with a first coat diluted with Thinner 845 (max. 20%). Then apply 2 coats of primer. If necessary, add thinner to aid application (max. 5%).
- Previously coated surface - sand, clean and dry the surface and apply 1 coat of primer. If necessary, add thinner to aid application (max. 5%).
- After approximately 4 hours (at 20°C) the primer is hand-dry and recoatable.
-
You can now easily apply Hempel Underwater Primer or a Hempel Antifouling of your choice.
Note: always wear protective clothing, gloves and a suitable vapour mask when working with Hempel Light Primer!

-
The materials, substrates or tasks a product is intended for. A general claim such as 'suitable for plastics' does not mean it works with every type of plastic; the specific substrate and its preparation still matter.
- Polyester boten, Stalen-boten, Aluminium boten, Houten boten

The technical product category, such as primer, resin, hardener or cleaner. It explains the product's purpose and helps you find other products with a similar function.
- 2K Primer
-
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.
- 2:1 (by volume)
-
The overcoating interval tells you when the next layer of paint, varnish or coating may be applied. Many multi-coat systems specify both a minimum and a maximum interval:
- Minimum overcoating time: the previous layer is dry or cured enough to accept another coat.
- Maximum overcoating time: the period during which the next coat can bond without extra surface preparation under the stated conditions.
Overcoating too early can affect drying or the finish. Once the maximum interval has passed, cleaning and sanding may be needed to ensure adhesion between coats. Temperature and film thickness affect the waiting times.
- 4 hours (20 °C)
-
The waiting time before an applied layer is dry or hard enough to sand without smearing or damage. Sanding too early can also clog the abrasive quickly. Layer thickness and temperature affect this time.
- 2 days (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.
- Approximately 8.2 m²/L
-
A specific thinner that can be used, where permitted, to adjust a product's application properties or viscosity. The correct thinner and maximum quantity depend on the product. Incorrect thinning can affect coverage, drying and curing.

- 2.5 L, 750 ml
-
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, Roller, Spray, Paint pad
-
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 360 minutes
