Installing epoxy at high temperatures can present several challenges, which can affect the performance and durability of the epoxy. Here are some common issues:
Accelerated Curing
High temperatures can cause the epoxy to cure much faster than intended. This can reduce the working time and make it difficult to properly mix and apply the epoxy before it begins to set.
Bubbles and Outgassing
High temperatures can increase the likelihood of bubbles forming in the epoxy. This happens because the higher temperatures can cause trapped air and other gases in the substrate or the epoxy mixture to expand and form bubbles.
Viscosity Changes
Epoxy resin and hardener may become too fluid at high temperatures, making it difficult to control the application. This can lead to sagging or running, especially on vertical surfaces.
Storage and Handling
Epoxy components have specific storage temperature requirements. High ambient temperatures will affect the shelf life and performance of the epoxy before it is mixed and applied.
Tips for Installing Epoxy at High Temperatures
Work During Cooler Parts of the Day: If possible, schedule the epoxy application for early morning or late evening when temperatures are cooler.
Use Temperature-Controlled Environments: If working indoors, try to control the temperature of the workspace using air conditioning or other cooling methods.
Mix Small Batches Only: Mixing smaller batches of epoxy can help manage the accelerated curing times and ensure proper application. Small batches are a useful tool at all temperatures.
Pre-cool the Materials: Store the epoxy components in a cooler environment before mixing and applying them.
Follow Manufacturer’s Guidelines: Always follow the manufacturer’s recommendations for temperature ranges and application procedures to achieve the best results. Support for Epoxy.com products can be found at Epoxy.com Technical support 352-209-5268 or email me at norm@epoxy.com.
