Loctite PL Roof Flashing Polyurethane Sealant, Black, 10 Ounce

This is good stuff. Costs double the Chinese stuff but it’s worth it. Keep Americans working. I used it to seal down two sets of 24” diameter risers on my concrete septic tank. Ran two thick beads on the mounting flange and it stuck that plastic ring down tight to the clean dry concrete surface. Also ran a bead in each riser ring. It’s great stuff!

This product was recommended to fix a front load washer seal with a tear on a You Tube video. This was a much cheaper way to fix the seal than the $379 replacement. It worked and I am very happy and will use the product for other repairs needing adhesive that is waterproof.

Perfect for what I needed

The product I received did not have the label PL S30 but I believe it might just be an updated label. It still worked otherwise and is a good product. I used it for rocks for a koi pond instead of roofing and it held just fine! Would probably go with another route in the future. I recommend using an entire tube and not saving a used tube for next time because it is super hard to use it after it has been opened on an earlier date.

Check out JeepAndBass.com and/or on Youtube for a video of this guy (Ray) using this stuff and how well it performs in a harsh (tons of bass) environment with his 6 12" subs making all of his doors look as if they were turned into liquid waves. Something most people will not understand the point of.. but shows the resiliency of this chemical/caulk. Very flexible but VERY strong!

I use this stuff to repair cracked cast iron drain pipes. Use disposable gloves. Smear a little on the pipe after wire brushing it. Then lay on a patch of screening. The kind you get in rolls to repair your screen windows. Cut a piece longer than the crack, then cover it with the sealant. Works like a champ and saves you the cost of a plumber.

This is solvent based stuff that sticks to everything. I use on heavy metal repairs. Seals out moisture completely. Red primer adheres to it very well. Please know that it takes several days to cure.

Does the job you need it to do but it's messy and thick and hard to use through my caulk gun. Wear gloves and have rags handy, almost impossible to clean it up or remove it from clothing etc
