Loctite Repair Putty Multi-Purpose

Loctite® Repair Putty Multi-Purpose is a two-part adhesive consisting of an epoxy resin putty and a hardener putty which are mixed by kneading. They react to produce a hard, tough, permanent and waterproof bond on a wide range of materials. Loctite® Repair Putty Multi-Purpose does not shrink and is resistant to most common solvents. It can bond to damp surfaces and cure under water. Loctite Epoxy Putty can be sanded, drilled and painted.

Step by step


Step 1: Safety Precautions

Wear gloves.

Step 2: Preparation

Surfaces should be clean and free from grease and oil. For better adhesion, slightly roughen the surface with a wire brush or sandpaper prior to cleaning. Cut off desired length of Epoxy Putty and knead until uniform color is obtained. Putty turns from blue to white when completely mixed.

Step 3: Application

Apply the putty to surface to be repaired within 3 minutes of mixing. Work putty firmly into the crack or hole. For bonding, place the putty between the surfaces and apply firm pressure to ensure intimate contact with both surfaces. If applying to a wet surface, apply forcefully and hold in place until adhesion takes effect. For a smooth finish, rub the putty with a damp cloth prior to hardening. Working time is approximately 5 minutes. After 45 minutes, the putty can be sanded, drilled or painted.

Step 4: Cleanup

Cured putty may be cut away with caution using a sharp blade.
