Q:Can this Lanco Siliconizer Crack Filler White Elastomeric be used as a protective coating around the bottom walls of a particle board shed ?

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.

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.
