WEST SYSTEM® epoxy has built a name for itself through decades of proven reliability and versatility in marine applications. However, its uses aren’t just restricted to this. Last month we brought you the first of a two-part Trade Secret on ways to use epoxy for your household repairs. This month’s second part shows you even more ways to save time and money on easy repairs around your home.
1. Bonding bricks and stone
WEST SYSTEM epoxy can be used to bond loose or broken bricks. If the mortar is solid and the gap is small, use a non-sagging epoxy/adhesive filler mixture thickened to a mayonnaise consistency. Apply a layer of the mixture to the inside of the cavity and push the broken brick back into place.
If the mortar is loose or even missing, you can make a bonding grout of epoxy and adhesive filler and masonry sand. For colour, add a little dry cement or mortar and apply it to the bonding surfaces, being careful to avoid getting epoxy on the face of the bricks.
Bonding stones with WEST SYSTEM epoxy is also a simple and easy process, perfect for decorative landscaping to achieve a dry laid appearance (without mortar). It is important to clean and dry the stones before starting the process. Then, use epoxy and adhesive filler thickened to the consistency of peanut butter to bond the stones in strategic places. This will prevent the stones from shifting or settling.
2. Repairing cracked concrete
WEST SYSTEM epoxy is great to repair cracks in concrete – all you need to do is clean the area around the crack, removing any loose debris and then pour or inject the epoxy into the crack. If you are trying to fill a larger crack, particularly on walls, you may need to thicken the epoxy with a bit of cement powder so that it stays in place when you apply to the seam of the crack. Once the epoxy has cured, you can seal the crack with a water-resistant filler so that it won’t shrink and fall out.
3. Repairing cracked plaster
Plaster is usually made up of two layers: a top layer, called the “white coat” and the other beneath it, called the “brown coat.” When a crack appears in the white coat on the surface, it is usually because the brown coat has cracked. To make the most effective repair, scrape open the crack with a “V” shaped tool well into the brown coat and wet the brown coat with epoxy, letting it stand for about an hour. Mix epoxy with adhesive filler to a peanut butter consistency and apply it deep into the crack. Leave the repair slightly concave so you can use a dry-wall compound to fill the white coat flush with the surface. After the epoxy has gelled, use a wire brush on it so that the topping compound can key into its surface.
