Question

post-test
when applying adhesives, all the following apply except:
a. use a plastic spreader and apply firm pressure.
b. completely saturate the mesh.
c. apply thin coats until the repair is slightly overfilled.
d. sand the backside of the repair to maximize strength.

Explanation:

To solve this, we analyze each option for adhesive application:

• Option A: Using a plastic spreader with firm pressure is a standard adhesive application technique.
• Option B: Saturating the mesh (like in fiberglass or similar repairs) is typical for proper adhesion.
• Option C: Applying thin coats until slightly overfilled allows for proper curing and build - up, which is a common practice.
• Option D: Sanding the backside of a repair is not a standard step when applying adhesives. Adhesive application focuses on the bonding surface (the front or the area being repaired), and sanding the backside doesn't contribute to the adhesive's function or the repair's strength in the context of adhesive application.

Answer:

D. Sand the backside of the repair to maximize strength.
