Titebond WeatherMaster Metal Roof Sealant, Silver – Premium Polymer Caulk for Aluminum, Copper, Galvanized Steel & Coated Metals, UV-Resistant – 62611, 9.5 Oz. Cartridge

Titebond WeatherMaster lives up to its name. I’ve used this sealant on multiple standing seam metal roofing jobs, and it performs exceptionally well. It adheres strongly to coated and uncoated metal, aluminum, steel, and even synthetic underlayments with zero issues. It skins over quickly, but you still have enough working time to tool it cleanly. Once cured, it remains flexible and completely weatherproof—even under full sun, heavy rain, and sub-zero temps. No shrinking, no cracking, no chalking. It also matches most standard gray metal roof trims nicely. Pros: Sticks to just about anything Paintable and low odor Remains flexible, won’t dry out or shrink Excellent color match for gray flashing and panels Whether you're sealing seams, fastener heads, or flashing details, this is a contractor-grade product that won't let you down. Highly recommended for pro use or demanding DIYers.

Use this to seal up a gutter hole. Lightly cleaned and dried the gutter but by no means did it perfect as there was standing water so just sorta dammed it back, and couldn’t scrub the grime and rust off. It stuck, and it’s held stoping the leaks for a few weeks now and a few storms. Very pleased.

Wellness how it holds up long term. Seems to be really good quality stuff from applying it though

Was able to seal holes on my metal siding, paste runs to much.

Had some leaking corners on my gutters and used this to seal them. They worked better than expected. I polished the gutters with a wire brush to remove and clean the previous seal. The water still sits there because I have to adjust the angle but no more leaks. There was a leak by my bedroom that was annoying to listen dripping at night.

Maravilloso producto cumple con lo que promete

Altamente recomendado. Trabaja excelente.
