Applying The Epoxy Coat

Rod finishes are made from 2 part epoxy resins that give a crystal clear, pliable finish that will protect the guide feet and their wraps and also add strength to the junction.

Some rod builders use a low build epoxy that requires multiple coats. The first coat will be applied and left to dry (usually 24hrs) and then the next coat will be applied. You will be using a high build epoxy. High build epoxies are applied in a single coat as they have much better coverage. Choosing a high or low build epoxy comes down to preference and what you are trying to achieve with the rod but for most situation a quality high build epoxy will suffice.

U Build Rods Ultra Clear Epoxy is a two component, solvent free, low viscosity protective coating which gives an amazing finish and is extremely durable. It even has excellent curing, even at low temperatures and high humidity.

Steps:

  1. Setting up the Dryer
    1. Once you have coated your rod it will need to remain in the rotisserie dryer for 3-4 hours so it is imperative to set up your work area somewhere that it will not be disturbed.
    2. Align the rod dryer with the rod dryer stands
    3. Install the rod but into the rubber chuck on the dryer. Make sure it has a good firm fit. Then lay the rod onto the rod dryer stands. Position the dryer stands, away from any guides that will get epoxy coated, where it will support the entire rod in a steady position.
    4. Turn the dryer on to make sure it works and is spinning smoothly. It should spin at about 8-9 rpm.
  2. Final Checks
    1. It is good practice to now make a final check of the rod.
    2. Re check the alignment of the guides.
  3. Any marks that get coated in epoxy are there forever so make sure you double check everything and remove any unwanted marks

  4. Mixing the epoxy – These mixing instructions apply for UBR Ultra Clear.

    Please refer to the UBR Ultra Clear Safety Data Sheet for complete safety guidelines when using UBR Ultra Clear Epoxy.
    Please wear appropriate personal protective equipment.

    1. In your mixing cup add 2 parts of A (2 millilitres) with 1 part of B (1 millilitre) by volume in a clean and dry mixing vessel. This should be enough to complete your wraps.
    2. Insert a mixing ball and attach the mixing cup to your UBR Mixer for 5 minutes OR…
    3. 3.3. Stir thoroughly for 5 minutes using a mixing stick. Scrape the edges of the mixing container to ensure complete and thorough mixing has been achieved. Keep your movements slow and the stirrer touching the bottom of the mixing cup. Stirring too quickly can introduce unwanted bubbles into the mix.

    WORKING TIME – Approx. 30 minutes at 25°C
    U Build Rods recommends using a UBR Mixer to mix the epoxy. Using a UBR Mixer ensures perfectly mixed epoxy. Inaccurate and or incomplete mixing may give inferior performance.

  5. Applying the Epoxy
    1. Turn on the dryer and make sure the rod is turning smoothly
    2. Dip your brush into the mixed epoxy and scrape off the epoxy on the side of the mixing cup. This will help remove some of the bubbles. The brush is now ready to apply to the rod.
    3. U Build Rods recommend the use of a quality UBR sable brush. A quality brush will improve your finish and you won’t spend time removing bristles from your coating. Brushes can be cleaned and reused.

    4. Dip your brush again this time being careful not to get any bubbles and apply it to the bottom of the wrap (towards the butt of the rod).
    5. Ideally you want to go about 0.5 – 1mm past the bottom of the wrap and create a clean straight edge. To do this use a steady hand and just move the brush into position and let the turning of the rod do all the work.
    6. Take your time and don’t apply too much epoxy at a time. You do not need to paint the epoxy on. You should just be moving the epoxy around using the brush to create an even coating and let the epoxy spread itself.

    7. Continue applying epoxy up the wrap until you get to the leg of the guide.
    8. At the top of the guide you also want to go past about 0.5 – 1mm and create a straight clean line.
    9. At the top of the guide there will also be a gap between the foot, wrap and rod. It is crucial to apply some epoxy into this gap. See figure 9-1. This will help prevent any water intrusion.
    10. If any bubbles have appeared in the coating you can remove these with the alcohol burner. Simply heat the epoxy and this will remove the air bubbles.
    11. U Build Rods recommend the use of an alcohol burner as it produces a clean flame with no contaminants and doesn’t produce soot. Using a lighter can “blacken” the finish. Using a heat gun can blow dust into the finish.

    12. Once you are satisfied with the coating move on to the next wrap and so on.
    13. If you applied any decals, additional wraps or writing do not forget to completely coat them with epoxy also.
    14. Once everything is coated leave your rod to rotate in the dryer for 3 – 4 hours. The epoxy will remain tacky for the first 6 hours and will only completely cure after 24hrs so be gentle with your rod.
  6. When using an alcohol burner be careful. Always work in a well ventilated area. Keep heat sources away from flammable objects and be sure to completely extinguish any flames.

Drying times are relative to a temperature of 25°C. Please refer to the manufacturer’s instructions for alternate drying times.

 

Congratulations you have completed building your first fishing rod.
