When using an epoxy anchoring system, what is a recommended practice?

Utilizing an anchor screen in a hollow wall or brick is a recommended practice when using an epoxy anchoring system because it helps to ensure proper anchorage and stability. An anchor screen provides a larger surface area for the epoxy to bond against, which is especially important in less stable materials like brick or hollow walls. The screen can help to distribute the load more evenly and mitigate the risk of damaging the substrate while also providing the necessary strength for the anchor to hold effectively.

The other options either pertain to practices that may not enhance the effectiveness of the anchoring system or may not address specific requirements of the material in which the anchors are being installed. For example, using a sealant on the anchor might not be necessary in all cases and could interfere with the epoxy’s bonding capability. Applying heat to cure the epoxy could alter the chemical properties and effectiveness of the product, and relying solely on plastic anchors could limit the strength and durability compared to a properly installed epoxy anchor system. Thus, employing an anchor screen is the best approach to ensure secure anchoring in such wall types.
