Hempel Underwater Primer – Step-by-step instructions
Follow these instructions for the best results in priming your boat:
Step 1: Protect yourself properly
Wear protective clothing, a respirator, and safety glasses. Painting work can involve harmful fumes and splashes, so safety first.
Step 2: Repair damage if necessary
If there are cracks, dents, or other damage on the boat's hull, fill them with a suitable fairing compound or epoxy filler.
Step 3: Shape by sanding
Once the patching compound has fully cured, sand the faired areas and their surroundings into a shape that matches the original surface. Use suitable sandpaper for the purpose.
Step 4: Apply Hempel Light Primer if necessary
If priming is being done for the first time or the surface requires additional protection, apply Hempel Light Primer before Underwater Primer. Check the required number of coats from the product's technical datasheet.
Step 5: Apply Hempel Underwater Primer
Apply Underwater Primer with a roller, brush, or spray gun. Work in a well-ventilated area and ensure that the conditions (temperature and humidity) are suitable for painting.
Step 6: Apply the necessary coats
Refer to Hempel's painting guide to determine how many coats you need. Generally, 2–3 coats are recommended to ensure optimal protection.
