What precaution should be taken before installing adhesive anchors in wet conditions?

Before installing adhesive anchors in wet conditions, the best practice is to ensure that the base material is dry or to use a moisture-resistant adhesive. This is crucial because the presence of moisture can impair the bond strength between the adhesive and the base material, potentially leading to installation failure and reduced load-carrying capacity of the anchor.

Using moisture-resistant adhesives is a common mitigation strategy, as these products are specifically formulated to bond effectively in damp environments. If the base material cannot be dry due to environmental conditions, selecting the appropriate adhesive allows for a reliable installation that maintains its integrity even in the presence of moisture.

Other options do not address the critical aspect of moisture's impact on the bonding process. For instance, deciding not to install under any circumstances may be overly cautious in some contexts where suitable materials are available. Increasing the quantity of adhesive is not a recommended solution, as it does not resolve the issue of adhesion compromised by moisture. Lastly, while using stainless steel anchor rods has benefits, it does not directly solve the fundamental concern of ensuring that the adhesive can effectively bond to the substrate in wet conditions.
