Is your old metal roofing starting to leak? Waterproof sealant for metal will stop the problem quickly and easily.
Waterproof sealant for metal adheres upon contact with metal surfaces, closing the gap on seams, joints, and around fasteners. SMP (silane-modified polymers) sealants, for instance, form a waterproof bond and can be applied on wet substrates. Once applied and cured, they remain flexible and are paintable. They can be used on a variety of surfaces including corrugated and galvanized steel, aluminum, stone, glass and concrete.
It’s quite simple to use! You will need:
- Caulking gun
- Some snips
- Clean rags
- Waterproof sealant for metal
Safety first: Work in a well-ventilated area and protect any surfaces you don’t want to get the sealant on. Always wear gloves when working with sealants.
Prepare the surface: Scrape off any old caulk, paint, or rust before applying the sealant. Get rid of any dust or debris. Please note: When removing old paint, it might be necessary to apply a fresh coating before actually utilizing the sealant, since the latter will usually only protect the joint area.
Apply product: Cut the end of the tube with snips or a utility knife so that you will get a nice constant flow of sealant. Force the sealant into any cracks or gaps with constant pressure on the trigger. After applying the sealant, spread it to a smooth consistent bead with a caulk tool or your finger.
