Making Your Own Vuba Vertical Primer Paste

Materials Needed

  • Fumed silica (Cabosil) – 4 to 5 liters (1–1.25 US gallons) per part
  • Part A and Part B (resin system)
  • Catalyst (follow manufacturer’s guide)
  • 5-gallon mixing pail
  • Mixing tools (drill mixer or paddle)
  • Measuring containers
  • Protective gear (gloves, mask, goggles)
Warning
Breathing fumed silica dust can cause serious lung damage and severe respiratory irritation.
Warning
Avoid all inhalation—use protective gear and handle only in well-ventilated areas.

Step 1: Prepare Your Workspace

  • Ensure a clean, well-ventilated area.
  • Wear appropriate protective gear.
  • Have all materials and tools ready.

Step 2: Mix Fumed Silica into Part A

  • Pour approximately ½ of the Part A bucket into a mixing container.
  • Gradually add 4 to 5 liters (1–1.25 gallons) of fumed silica.
  • Mix thoroughly until the consistency is slightly thicker than Vaseline.

Step 3: Mix Fumed Silica into Part B

  • Pour approximately ½ of the Part B bucket into a separate container.
  • Gradually add 4 to 5 liters (1–1.25 gallons) of fumed silica.
  • Mix until the texture resembles a very hard snowball or tennis ball squishiness.
Idea
On hotter days, add more fumed silica, especially to Part B, to maintain consistency.

Step 4: Combine Part A and Part B

  1. In a clean 5-gallon pail, add:
    1. A softball-sized scoop of Part A
    2. A softball-sized scoop of Part B
  2. Add the catalyst according to the manufacturer’s guide.
  3. Blend thoroughly.

Step 5: Add Dry Mix

  • In another clean 5 gallon pail, add ¼ bucket of blended dry rock.
  • Add 1 softball size of combined Part A and B from Step 4.
  • Then add another ¼ bucket of dry blended rock, totalling half of a 5 gallon bucket.
  • Blend thoroughly.

Step 6: Test Consistency

  • Test the paste on the inside wall of the bucket.
  • If it sags or falls, add more fumed silica to thicken, ½ litre at a time
  • Mix again and retest.

Final Notes


Alert
This is a general guideline—adjust based on temperature and working conditions.
Notes
The goal is to achieve a 1:1 mix ratio of thickened Part A and B for a usable paste.
