Detailed 3D Archery Target Repair Instructions

READ THROUGH INSTRUCTIONS AND THE TIPS, TRICKS, & HINTS PAGE ENTIRELY BEFORE USING MATERIAL. ALSO, BE SURE TO USE A QUALITY DIGITAL SCALE TO PROPERLY MEASURE THE FOAM CHEMICALS.
CHEMICAL: Always store and use foam chemical material at room temperature. Material works best when mixed and used at 70 plus degrees Fahrenheit.

TARGETS: Temperature + Moisture (excess humidity). Targets must be dry and at room temperature.

SAFETY: Keep out of reach of children. DO NOT eat, drink, or feed to anything! Use latex gloves, safety glasses and use only in well ventilated area. When burning in scoring rings, do so outside. Use a box fan to move fresh air across work surface.

CLEAN UP: After foam is cured, you can scrape up or peel spills off many surfaces (i.e. floor, tile, etc.). Acetone works well to remove from mixing device and or bench tops.

FOAM: The warmer the ambient temperature is, foam material, target, air temperature, etc., the higher the yield will be from the foam material.

RANGE PRECAUTIONS: Never shoot any 3D target repaired or new target with low poundage child bows, blunts, or any point not designed to penetrate the foam! Arrows will ricochet back towards the shooter and could cause SEVERE injury!

1. Make a scoring ring template using the clear plastic sheeting for the 8, 10, and 11 rings. Start by marking the center point the 11 ring. This will facilitate burning in the scoring rings with the compass tool.

2. Using saws all, cut out and remove all shot up and or loose material, also use pry bar to remove loose or semi loose foam in order to avoid possible cuts from lost broadheads.

3. Begin with the target completely dry and all materials including repair foam and target at room temperature. Check to make sure foam is completely dry (use moisture meter) if you have any doubts.

4. Staple on 6 mil clear plastic sheeting for forms. Also, if necessary use cardboard to back up plastic sheeting and staple or duct tape to secure. Note: keep staples no more than off opening and no more than 1/8 apart. Important: leave an opening at a point in order to pour in mixed material, to allow a vent or escape port, for expanding material/over pour.

5. Mixing & pouring material: Target, resin and hardener should be at room temperature. Also, the target should be dry.

A - Mixing containers/vessels

  1. Milk jug that is clean and dry (cut off spout to enable insertion of mixer
  2. Popcorn container, QT or Gallon, new and dry (1500 grams max resin)
  3. For smaller pours plastic solo cup (300 grams max resin)

B - Shake up Resin (B) to re-suspend pigment that settles on bottom (Resin should be somewhat bubbly when poured into mix container). Pour desired amount into mix container on gram scale. Then calculate total weight including Harder (A) by multiplying Resin (B) weight in grams x 1.45. This number will be your total. Example 100 grams of (B) x 1.45 = 145 total. Pour (A) into container until the scale reads 145 grams.

C - Remove container from scale. Use mixer supplied on a high speed electric hand drill (2500 rpm or better). Mix for 30+ seconds (at temperatures above 25 degrees C/ 85 degrees F, mix A & B for ONLY 20 seconds). Then place mixer in an open container of acetone and pour material into form. Use a paint stir stick to help move out material and do this quickly.

Once the foam mixture starts to become warm/hot it will expand rapidly. You should have the mixture in place before this reaction starts to take place. Remember to leave an opening in your form where you pour in the mix for a blow out or over pour. Once poured do not handle, kick, drop or push on form. Let the foam cure completely for 6-12 hours, preferably overnight.

D - If you over pour or over estimate amount needed and have to trim off excessive amounts of cured material, save pieces in box or bucket. This material can be placed in cavities of a future pours (reused).

E - If you under estimate and have a short pour, wait 30 minutes and make a second pour to finish.

F - Let target set for 6-12 hours before continuing to next step.

6. Remove plastic form and all staples. Trim excess foam (use serrated bread knife, saws all blade or whatever tool suits you (the aforementioned work very well). Then proceed to shape using 3m Scotch-Brite pa #9419.

7. Scoring rings: Apply template, mark center of 11 ring. Trace 8 ring and 10-11 if needed. Use 40 watt min or hotter soldering iron to burn in scoring rings.

Important note: when burning or melting scoring rings with soldering iron, you must be in a well ventilated area and have a fan moving air across work area, fumes are very hazardous, I cannot stress this enough!

After scoring rings are replaced, paint with a good quality outdoor flat latex 100% acrylic paint. Let target dry for 2 days at room temperature and start shooting.
