Q:Can this Lanco Siliconizer Crack Filler White Elastomeric be used as a protective coating around the bottom walls of a particle board shed ?
by|Sep 22, 2023
1 Answer
Answer This Question

A:  Hi Rick, yes you can use the Lanco Siliconizer Crack Filler 1 Gal. White Elastomeric Roof Patch as a protective coating around the bottom walls of a particle board shed, but we suggest for you to use the Lanco Aqua -Proof Prep which is easier to apply and you would not need to top coat it as it is inside a shed and not exposed directly to the sun.

      Answer This Question

      A:  Hi Randy, we have 4 different Lanco Siiconizer Crack Filler, it all depends what you want to apply with, example we have to be applied with brush or knife. You maybe can try the brush one, but you want to make sure that the cracks are completely filled in.

          Good stuff
          I like this Lanco 1-gallon crack filler the consistency of peanut butter. I used Lanco over mesh tape & Karnak 19 flashing cement after full cure. So it’s clean area then Karnak 19 than mesh tape add second coat of Karnak. Let cure 3- months then 1 coat of Lanco then paint 2-coats exterior paint . I like that you can paint over the Lanco crack filler for added protection.

            Applied the Siliconizer as instructed. Now hoping for energy savings and a more leak proof roof. Thought the stuff was on the expensive side at $89.99 for a 5 Gallons Bucket.
