The Gorilla Waterproof Patch & Seal Tape is an excellent choice for shower repairs and other waterproofing tasks. Its adhesive strength is impressive, creating a permanent seal that effectively blocks air, water, and moisture. This tape is highly versatile, working well on various surfaces such as roofs, pool liners, rubber, and plastic.

It is designed to be used both indoors and outdoors, even in challenging conditions like rain or underwater scenarios, which makes it highly reliable for shower use. The tape's thermoplastic olefin material is durable and weather-resistant, ensuring it can withstand moisture and UV rays without deteriorating or yellowing over time. This durability contributes to its long-lasting effectiveness after application.

Additionally, the tape is flexible enough to conform to irregular surfaces, allowing for repairs on cracks, gaps, and tears in different materials. Users will find it relatively easy to apply, thanks to its strong adhesive and conformable backing. Some may find the application tricky on uneven surfaces and might need to ensure proper alignment to avoid wrinkles. Despite this minor drawback, the Gorilla Waterproof Patch & Seal Tape stands out as a reliable, durable, and versatile solution for waterproofing needs in showers and beyond.

Flex Tape, measuring 4 inches by 5 feet, is a highly versatile and robust waterproof tape designed for a variety of repair tasks around the home, RV, roof, plumbing, and pool areas. One of its most notable strengths is its adhesive power; it can bond effectively to numerous surfaces including wood, glass, cement, ceramic, metal, and more. This makes it an excellent choice for those needing a reliable solution for quick fixes and emergency repairs.

Additionally, its water resistance is exceptional, as it can be applied even under wet conditions and can withstand extreme weather, thanks to its UV resistance and wide temperature range. The tape's thick, rubberized, and flexible backing allows it to conform to different shapes and objects, providing a watertight seal that blocks water, air, and moisture instantly. This flexibility and the tape's ability to work underwater are significant benefits for diverse applications.

However, there are some drawbacks to consider. The product’s durability is generally good, but some users have reported it may not hold up as well under constant water pressure or heavy usage over time. The ease of application is relatively straightforward, but due to its strong adhesive, it can be challenging to reposition once applied, so precision is required during use. The gray color might not be aesthetically pleasing for all repairs, as it may not blend in with certain surfaces. These minor issues aside, Flex Tape remains a highly effective and reliable option for waterproof repair needs, particularly for versatile indoor and outdoor use.
