Coating Jobs: Using 2 part foam for flashings


What portable or disposable kits are others using around penetrations on low slope coating projects?

I am asking specifically for non system warranted jobs.
We do smaller projects using Gaco S20 and the GacoFlashFoam 120sf kit is pretty pricey ($3.20sf) compared to others. We haven’t had the need for a 2 part foam yet however a recent bid opp calls for it.

Touch 'n Seal has a 600sf kit for around $1.00/sf. I’m not familiar on compatibility when it comes to types of foam on certain types of coatings (silicone based, water based etc).

I am looking for a less costly solution for my clients using S20 when foam is more effective around curbs/pipes/scuppers.
