Can you use this product without tape when repairing stress cracks?

Thank you for posting your inquiry on DAP Premium Lightweight Joint Compound. Because this is a hard setting repair filler/compound, it should not be used in applications that may be subject to movement (expansion/contraction/flexing). While the use of reinforcing tape (Example: fiberglass mesh) may help to stabilize the joint (limit movement), should movement occur, cracking will likely result. Should you have any additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.
