Thank you for your feedback. We’re sorry to hear that you experienced issues with the product. Based on your description, it appears that the material was laid in conditions that were too wet. As stated on our website, this product should not be installed in wet conditions, as moisture can cause it to clump and affect its ability to bind properly.
For best results, we recommend laying the material in dry conditions to ensure a firm and stable finish. If you need further guidance, our team would be happy to assist.
