26 Chapter 12 Maintenance: Repair of the Body
REPAIR OF THE HOUSE OR SMOKE ALARM PLASTIC
Materials
Super glue
ABS or PVC clear medium bodied glue
Fiberglass mesh
rubber gloves
1. Hold the crack together tightly so that the glue you put on the inside of the body does not
run through the crack on to the outside of the body. This would etch into the plastic.
2. If there are pieces of plastic reinforcement across the seam or crack that are unglued, PVC
or ABS glue can be used between the reinforcement piece and the body. A clamp could be
used to hold the plastic tightly together while drying.
3. Cut a piece of fiberglass mesh to cover the crack.
4. Position the body, so that the seam or crack is horizontal to the table. This will keep the glue
from running. Apply some of the PVC or ABS glue along the seam, only on the inside of the
body. Check to make sure that the glue is not running through the crack on to the outside of
the body. Note: Avoid getting the glue on your hands.
5. Immediately put the fiberglass mesh on the glue and pat it down to saturate into the glue.
6. Apply some more PVC or ABS glue over the fiberglass mesh to saturate it some more.
7. It will dry to the touch in about 30 minutes. Allow 24 hours for complete drying.
8. For cracks that need more strength, glue a piece of ABS plastic across the crack with PVC
glue.
General
Precautions:
Do this in a well ventilated area.
Use gloves to avoid getting glue on your hands.
Avoid getting the fiberglass on your skin or clothing. The fiberglass will not hurt you, but
could cause skin irritation.
For further precautions, read the super glue, PVC, and ABS container labels.
