About Injectadeck

Rotted deckInjectadeck Is a very carefully engineered marine foam and adhesive All foams are not created equal! Injectaeck is water catalytic and becomes very hard and adhesive when it contacts moisture. Leave the water in your deck, gunnel or hatch, thats the magic, no cleaning.. This water catalytic foam is known to reverse moisture meter tests on vessels. 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 efficently by filling the VOID. You don’t have to peel up your fiberglass deck and replace it costing thousands of dollars. Injectadeck will 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”.

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 is a few  ounces of liquid or 2 to 3 cups of foam aka: 8″ diameter x 1″ thick, soft spot. These 22oz cartridges = 1120oz of foam or 10sq 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. This product is attracted to moist environments, and water helps in adhesion, expansion and curing. Most boat decks are wet rotted and perfect candidates for this product. If you have dry rot when you drill your holes, lightly spray your newly perforated deck down with water and in 30 minutes, inject your deck. 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 5 minute work time. After 15 min it hardens.

Tip: drill a relief hole in the low point of every fiberclass sandwich core structure for a water drain and vent. Wet areas are better than dry.

We don’t recommend Injectadeck for use on Transoms. While people seem to like it for that, transoms would be considerd 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.

  • 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!
