Sprayman Fire Block Foam Sealant
The sheet prints UL 723 flame spread 10 and smoke developed 15, undated and with no tested thickness; the store still says "fireproof."
2 of four things confirmed
These are the four things we could check for a fire block can, and nothing else. Not a performance score: nothing on this page was applied or tested by us. How the fire block page is ordered.
- Brand data sheeta technical data sheet is published by the brand, without a date or revision on it
- Claim checkableThe sheet prints a surface-burning pair, UL 723 flame spread 10 and smoke developed 15. This category asks for a fireblocking result, a through-penetration or room-corner method with a listing or report number, and the sheet has none. It also prints no tested thickness and no date, so neither number can be pinned to a version or a test set-up.

Research summary, not a hands-on test. Product claims on this page are attributed to the sources and dates shown. Before use, read the exact product label, the current safety data sheet and the application instructions, and confirm ventilation, protective equipment, occupant isolation and re-entry or reoccupancy conditions. A surface-burning classification alone does not establish approval to leave foam exposed or to use it in a particular assembly.

Our reading
The sheet prints UL 723 flame spread 10 and smoke developed 15, which is the same pair Kraken Bond prints; the two TYTAN sheets print 15 and 10. Two things the sheet does not carry keep the mark off: the thickness the sample was tested at, without which a surface-burning number describes an unknown assembly, and a date or revision, without which it describes an unknown formulation. And a surface-burning result is not a fireblocking result. This page is marked on whether the can can be shown to stop fire spreading through a penetration, which is a different test with a different number, and no Sprayman document answers it. The store wording is a separate problem: "fireproof" is wrong for any foam sealant, and "ASTM E84201" is not a designation as written. The sheet is on the brand page, behind a button marked TDS.
Still open
- The sheet carries no tested thickness, so the flame spread and smoke figures cannot be tied to an assembly.
- The sheet carries no date or revision.
- The ICC-ES reference has no report number on the straw page; the gun page cites "ICC-ESL-1058."
- The word "fireproof" remains on the brand page.

Each displayed price is what that listing showed on the date printed in its row; ratings were read October 29, 2026. A pack with no price is one where the listing showed none, where the figure contradicted another variant, or where its last successful read passed the freshness window. Prices are snapshots, each dated where it appears, not live figures, so check the seller before you pay.

Jobs where a can from this category is part of the answer
These pages name the category rather than this particular can. Each one sets out the constraint that decides the product for that assembly, the code section that applies, a worked quantity example, and where foam is the wrong answer.
- Attics As fire block foam. Where a penetration between floors is a fireblocking location, the orange can needs a real surface-burning result; the fire block page sorts the claims.
- Garages As fire block foam. Penetrations through the separation wall are where a fireblocking claim is actually asked for.
