Defend your foundation.
Snap Plate Mold Defender™ is a commercial strength, spray on formula applied to wood surfaces to create a moisture and fungi defense. Blue for stick framing: apply under, around and on all wall plates and sub floors before the building is closed in.
Trapped moisture under a bottom plate will not dry out the way it does on vertical lumber. Treating the plate line during layout is the simplest way to defend a wet plate or subfloor before the walls stand and the drywall goes on.

Application instructions
Best results start with lumber and subfloors that are not wet.




Easy and cost effective to apply
With our battery powered 4 gallon backpack sprayer. One pail and one sprayer treat the plate line on a house in about an hour, with the crew you already have.

Protect the connections.
Mass Timber Connection Defender™ is the same advanced formula as Snap Plate Mold Defender™ with no blue dye: an eco advanced, non-toxic, very low VOC water repellent with a durable fungi strength additive, factory applied and sprayed inside mass timber connections where trapped moisture does its damage.
Even mass timber gains important risk reduction during construction, before drywall and sprinklers are added, when treated to achieve stronger fire performance. All wood structures, including mass timber, are vulnerable to mold and rot during wet weather construction.
- Same advanced formula as Snap Plate Mold Defender™
- Factory apply and spray inside connections
- Defends against damage caused by trapped moisture
- No blue dye
- Commercial strength
- Non-toxic, very low VOC
- ASTM G21 tested


Defend the deck before the walls go up.
Rain and snow land on the floor sheathing for the whole time the frame is open. Once the walls are standing and the drywall is on, the deck under the plates is the one surface on the job nobody can reach again.
Pro Subfloor Defender™ is applied to the subfloor during layout so a wet deck sheds water instead of holding it, and does not become a mold callback after the building is occupied.
- Apply to floor sheathing at layout, before the walls stand
- Water repellent protection for OSB and plywood decks
- Helps prevent mold growth under wall plates
- Commercial strength, applied with the same sprayer as Snap Plate Mold Defender™




Class A floor trusses for safer wood structures.
Supporting today’s best mold and fire builder risk reduction.
There is more to reducing fire and wildfire risk than just changing vents and roofing. Hot micro wildfire dust can penetrate new roof vents. Adding Class A trusses or roof framing members, combined with better roofing and ember vents, creates true risk reduction.
The best risk reduction for insurance underwriters starts with the structural wood system. True risk reduction starts in the lumber bones of the home.

Why Class A trusses matter



In honor of the thousands of families across America who have suffered devastating fire loss, we believe in building above the code.
