About Injectadeck

Rotted deckInjectadeck Is a very carefully engineered structural marine foam and adhesive. All foams are not created equal! Injectadeck is water catalytic and becomes more adhesive when it contacts moisture. Drain the water from your panel, deck or hatch with a drill hole or two, no cleaning. The excess water will be forced out or gobbled up. more water drops the hardness and expands the foam and the amount of coverage and the adhesive qualities go up. Traditional adhesives cannot do this, ever! The amount of holes you have to drill with adhesives is a rivet pitch… Injectadeck? a few holes per sq ft’ish. This water catalytic foam is known to reverse moisture meter tests on vessels through displacement and the fact that it consumes water, rides on it, becomes more reactive. Injectadeck is light, waterproof, with no shrinkage over time. Injectadeck also has an antibacterial anti-mold pesticide to stop the rot and anything munching. Injectadeck wipes out the severe soft spots in a boat decks & gunwales quickly and efficiently by filling the VOID. You don’t have to peel up your fiberglass deck and replace it costing thousands of dollars over months. Git on the water! Injectadeck can also rescue your boat sale or classic keeper. It was created by an aerospace applications engineer who has relied on various structural foams to provide lightweight solutions for Air, Land and Sea. Since the inception of foam filled products like boats, surfboards and aviation products? The problem has been that two part foams expand fast and uncontrollably when mixed and require larger holes for “the pour”. Areas that are dry makes harder foam than wet, and through our latest formula and process instructions we are able to adapt to all voids wet and dry.

Injectadeck alleviates that issue allowing you to mix and inject thru a small hole simultaneously allowing you to fill the space or void. A click of the gun and then click the trigger release, gives an 8oz cup of hard foam is a good guide.. These 22oz cartridges = 1120oz of hard foam or 8 sq ft of dry void. Sloppy wet deck? 10 sq ft to 12 sq ft of bad wet rot depending on wasted product. While you will have to work fast filling all your holes so the product does not harden in the mixing tip. The type of foam injected is a hard and resilient structural foam that can support heavy loads with little or no collapse of the closed cell waterproof structure. Expanding six times its size it can be classified as a 12lb foam which you could dent….with a hammer. If you add a lake of water it will expand more and become weaker down to approximately an 8lb foam or balsa hardness.  Most boat decks are wet rotted and perfect candidates for this product. You must drill small drain holes from the bilge or bottom. The small cavity in the photo would just need a light injection of an ounce or two. Once you pump a shot in, wait 10 min and you can step on the area and shape the foam if a bulge develops, it has a another 5 minute work time. After 20 min you can “stepshape” it hardens after 30 min. Gassing stops in 12 hrs, falling temp is best for plugging.

Tip: drill a relief hole in the low point of every fiberglass sandwich core structure for a water displacement drain and gas vent.

We don’t recommend Injectadeck for use on Transoms. While people seem to like it for that, transoms would be considered a critical component in the aviation world. Injectadeck does not “soak in” to any solid material it merely fills the void left behind from wet rot bacteria or the breakdown of solids

The reason epoxies do not work as well as injectadeck is that epoxies cannot stick to wet dirty surfaces like water catalytic injectadeck. Also epoxies required so many holes and injectadeck does not. Lastly epoxies when they crack and break are as sharp as a knife as they cut through your bottom layer of fiberglass and drop into your bilge or cabin liner.

Once you fill all the voids in your boat, you can become coastguard approved for commercial use! You boat can’t go to the bottom. Flotation foam is a sponge, injectadeck is forever.

  • John Satazahn Seattle WA “I installed it my Twin diesel trawler transom, alot of water came out and I passed the moisture survey”
  • Mike H. L3 Eng, Crestview FL “I ordered my injectadeck kit on 10/2 and it came fast, 3 days”
  • Jim Stubbs Tampa FL “45′ Silverton rotted gunnels, I used a 2″ clear plastic tube on the and run in the gunnels, for my injections, Survey passed!
