Which type of glue is best for outdoor projects?

For outdoor projects, the most suitable glue is typically one that is designed to withstand environmental conditions such as moisture and temperature fluctuations. Type I and Type II glue references generally correspond to different ratings of water resistance provided by the American Wood Council.

Type I glue is waterproof and suitable for continuous exposure to moisture, making it ideal for projects that will be exposed to the elements for prolonged periods. Type II glue offers resistance to water, but is meant for projects with limited exposure to moisture, thus not as robust as Type I.

Since both types of glue offer varying degrees of water resistance, utilizing both Type I and Type II can cater to different needs in an outdoor setting. This means projects that might not require the highest level of waterproofing can still benefit from the attributes of Type II glue, while more demanding projects can rely on the superior performance of Type I glue.

Therefore, stating that both Type I and Type II are appropriate for outdoor projects acknowledges the range of options available to the contractor, allowing for flexibility according to the specific demands of each task.
