How much should you apply to a wood bracing strip to give extra support to a cabinet shelf?

Thank you for the question. Because you are intending to support a vertical load situation after installation it is important to apply an ample amount of adhesive so there is sufficient body between the two bonding surfaces. Do not worry about squeeze out since this can be easily cleaned with water before drying. The success of your project will depend upon the amount of surface bonding area available, adequate surface prep for both surfaces and the maximum weight the shelf will be supporting. Given the nature of the project, maximum holding or bond strength may at least 7 days to occur under based at 77°F (25°C) and 50% RH
