Vinyl liner damage doesn’t always happen in convenient places or at convenient times. A puncture below the waterline or a slow leak discovered mid-season can quickly lead to water loss, liner stretching, and more costly repairs if not addressed promptly. Draining the pool to make a repair is often impractical and can introduce additional risks. The Poolmaster Wet Vinyl Patch Kit – 4 oz (30279) is designed to allow effective vinyl liner repairs to be made underwater, without lowering the pool’s water level.

This larger-capacity kit uses a pool-specific vinyl adhesive that bonds directly to wet surfaces and cures into a clear, flexible seal. Once applied, the patch moves with the liner rather than becoming brittle or peeling away. The 4 oz size is ideal for larger repairs, multiple punctures, or service professionals who need more material on hand for repeated use.

This is a vinyl repair solution engineered specifically for pool environments—not a general-purpose adhesive repurposed for underwater use.

Why Immediate Vinyl Liner Repair Matters

Vinyl liners operate under constant outward pressure from the surrounding water. Even small punctures allow water to migrate behind the liner, which can cause the damaged area to stretch and tear further over time. Left unaddressed, minor leaks can lead to liner shifting, wrinkles, base erosion, and significantly higher repair costs.

The Poolmaster Wet Vinyl Patch Kit – 4 oz allows repairs to be made as soon as damage is discovered, helping stop leaks early and preventing small issues from becoming major liner failures. Prompt repair is one of the most effective ways to preserve liner integrity and extend liner life.

Engineered for True Underwater Application

Unlike dry-only patch kits that require draining or lowering the pool water, this kit is formulated specifically for wet application. The adhesive cures underwater and remains flexible after bonding, allowing it to withstand liner movement, temperature changes, and continuous submersion.

When applied correctly, the patch forms a durable, watertight seal that blends cleanly with most vinyl liners and resists peeling over time.

Designed for Vinyl Pool Liners and Inflatable Vinyl

This kit is intended for vinyl-based pool materials. The adhesive bonds to vinyl surfaces without becoming overly rigid, which helps reduce stress at the repair site. It is commonly used on in-ground and above-ground vinyl liner pools as well as inflatable vinyl pool products and accessories.

It is not intended for use on fiberglass, concrete, or rigid plastic surfaces.

When to Use the Poolmaster Wet Vinyl Patch Kit – 4 oz

This wet vinyl patch kit is ideal when:

• A puncture or tear is visible in a vinyl pool liner

• Multiple repairs are needed or a larger repair area is involved

• Damage is below the waterline and draining is not practical

• Immediate repair is required to prevent further tearing

• A service-grade quantity of adhesive is preferred

Using the correct repair kit early helps stop leaks before they spread and reduces the risk of more extensive liner damage.

Practical Repair Solution for Pool Owners and Service Professionals

For pool owners, the 4 oz kit provides added capacity for handling larger liner issues without draining the pool. For service professionals, it offers a dependable, job-ready solution for repeated on-site repairs where speed and reliability matter.

When used properly, a vinyl patch can significantly slow liner deterioration and delay the need for full liner replacement.
