Small Practical Tips While Epoxy Resin Mixing

Epoxy puttyEpoxy Putty: Image by Steven Vance via FlickrYou may already be familiar with the Epoxy® brand of epoxy that we often use to attach broken objects around the house. However, that's the instant adhesive version, which has a weaker adhesive than the industrial type. When installing flooring tiles or when attaching together some furniture parts, such as shelves or table legs, a custom mix of resin and hardener is created.

Epoxy resin mixing requires careful measurements of resin and hardener. The ratio for a producing a mix with strong adhesive properties is 1:1 with 1 part resin and 1 part hardener. For a more malleable mix, you should combine 5 parts of resin to 1 part hardener. For example, take only 25 ml of resin and mix 5 ml of hardener into it. With a wooden spatula, stir the liquid mix for 2 to 3 minutes to let in the air bubbles into it to form a soft, semi-solid mixture.

Beware of the type of container you put the resin mix into. It's safer to place the resin mix in containers made of wax-free paper, plastic or metal. The intense heat of the exothermic resin mix might burn through foam containers, while it could break those glass containers easily. In addition, producing a quart or less of the resin mix helps reduce the temperature of the compound. Moreover, epoxy resin mixing does not need fire to cure the mixture. It simply needs 10 minutes for a quick, but thorough application on a surface, on areas that connect furniture parts, and underneath the tiles during floor installations.

A quart of this soft mix is sufficient for coating the floor, outside walls, and the hull of a boat. Producing more than a quart will expose the extra supply of resin to air, which reacts to the mix and hardens it. Aside from coating, a resin mix is also used as filler material for body contouring of boats and cars. After sanding and polishing, the surface of the contoured shape looks shiny and smooth like fiberglass. This hard material protects surfaces from scratches as well as fire and water damage.
