Keep your pool protected and looking great with our professional pool mastic replacement services. We specialize in sealing and repairing mastic joints around your pool deck, coping, and expansion joints using quality mastic pool caulk.
What Is Swimming Pool Mastic?
Swimming pool mastic is a flexible, waterproof sealant applied between the pool coping and pool deck. It acts as an expansion joint, allowing movement without cracking or shifting. This helps protect your pool structure from water damage and soil erosion.
Pool Mastic Colors
We offer a wide range of pool mastic colors to match your deck and coping. From sand and gray to tan and white, our color options ensure a clean, seamless look around your pool.
How Long Does Mastic Take to Dry?
Mastic typically takes 24 to 48 hours to cure, depending on temperature and humidity. During this time, avoid water exposure and foot traffic around the mastic joint sealant to ensure proper bonding.
How to Replace Your Pool’s Mastic
- Remove old mastic from the expansion joint.
- Clean and prep the joint for proper adhesion.
- Insert foam backer rod to support the mastic.
- Apply mastic pool caulk evenly using a caulking gun.
- Smooth the sealant and allow 24-48 hours to cure.
