What Customers Are Saying

The masonry caulk product received mixed reviews. Many customers found it effective for filling and sealing cracks in various masonry surfaces, reporting it was easy to apply and provided a professional finish. However, some users experienced issues with the caulk not drying or hardening properly, remaining tacky, or shrinking over time. A few also noted color mismatches. Overall, the caulk seems suitable for repairing small to medium cracks, but users may need to work quickly and apply multiple coats, especially in dry, warm conditions.

Hard to paint over

Would Recommend

Worked really well and is paintable but if using a light paint cover, it will require multiple coats to cover up.
