Gorilla Waterproofing Spray Clear
This product provides a flexible rubberized coating that seals out water, air, and moisture. The spray nozzle offers a controlled pattern for a clean, even coat, and the self-leveling sealant fills small gaps and cracks to form a watertight seal. It remains temperature- and UV-resistant after drying. Best for: outdoor inflatables and surfaces exposed to sun and weather. Caution: avoid excessive build-up on delicate fabrics that may soften if overapplied.
Flex Seal, 14 oz 2-Pack
Flex Seal offers a transparent, rubberized coating that seals leaks quickly and remains flexible for long-term use. It can be painted after drying and seeps into cracks and holes for strong adhesion. Best for: patching and sealing inflatable seams, gutters, and roofs where a stay-flex finish matters. Caution: while highly versatile, ensure the surface is clean and dry before application for best results.
Gorilla Waterproof Patch & Seal Black
This rubberized sealant spray focuses on sealing out water, air, and moisture with a durable coating and a user-friendly spray pattern for even coverage. It is temperature- and UV-resistant, supporting long-term repairs. Best for: targeted leaks on inflatable items such as air mattresses or boat inflatables. Limitation: may require careful surface preparation around large tears to ensure the patch bonds properly.
Alien Tape Sealant Spray 2Pk
Alien Tape Liquid Sealant Spray provides a heavy-duty rubber barrier that stops leaks and creates a durable, waterproof seal. It’s designed for easy spraying and drying on a range of materials, aiding quick repairs. Best for: temporary to semi-permanent fixes on inflatable gear and household items. Caution: for large or high-pressure leaks, use as a supplementary sealant rather than a sole repair method.
PVC Stitch Liquid Patch
PVC Stitch is a heavy-duty patch kit designed for PVC and PU inflatable surfaces. The liquid patch becomes a permanent seal as it dries, offering a simple patch-and-go solution without separate patches. Best for: air mattresses, inflatable boats, and pools with PVC components. Limitation: recommended for surfaces that can tolerate a liquid-on-top patch rather than fabric fabrics that stretch or flex significantly.
Buying Guide: How to Choose the Right Spray Sealant for Inflatables
- Surface compatibility: Pick a sealant that adheres well to PVC, rubber, fabric, or plastic depending on your inflatables. Some sprays bond better to PVC and rubber, while others work in mixed-material gear.
- Seal type: Determine whether you need a full-surface sealant, a patch-friendly coating, or a leak-stopping spray for seams. Rubberized coatings are versatile for large areas, while liquid patches excel on small tears.
- Durability vs. flexibility: Choose products that stay flexible after drying to prevent cracking with inflation and movement, especially for pool floats and air beds.
- UV and temperature resistance: Outdoor inflatables benefit from UV-stable formulas that resist sun damage and temperature swings.
- Application ease: Consider spray pattern control, self-leveling properties, and whether the product dries clear or can be painted to blend with the surface.
- Repair scope: For major leaks, combine a sealant spray with a patch kit to reinforce the repaired area.
Frequently Asked Questions
