Some decks are straight laid and others have the planks sprung to follow the sheer. Straight laid decks are far easier to install. What we do to install sprung decks is clamp ,wedge and weight.
We take small blocks of plywood
, about 2"x 3", the thickness of the teak planks being installed and super glue these to the sub deck. You can use hot melt glue but super glue works better. The technique is to apply glue to the block and spray the activator to the deck and then press the block down where you want it. With this method the glue is not as permanent and will bond in 2-3 seconds. Then when you want to remove it a sharp blow with a hammer will usually remove it. Or use a chisel bevel down and pop it off.
We tape the sides of the block with mylar packing tape to prevent epoxy from sticking to them.
For the first plank you glue the blocks down along the inner edge of where you want your plank. This means you are gluing in an area that will be under the next plank. We then use small clamps to pull this first plank tight to the blocks. After a dry fit we wipe the plank with denatured alcohol, then apply epoxy to the sub deck with notched plastic spreaders,
and install the plank.We use 25 lb bags of lead shot for weights.
It's very important to be meticulous cleaning
up the squeezed out epoxy. We keep qt bottles of alcohol and boxes of paper rags and trash buckets handy. We also like the little black plastic mixing sticks that West Systems sells. The chisel end of these works well or cleaning
and doesn't scratch.
If you need to glue a block down on a finished surface we put masking tape down first. This works well as the load is in sheer.
On subsequent planks we glue the blocks in far enough to allow f
or a small plywood
wedge to push between the block and the plank to tighten up the seam. We make seam spacers of starboard as the epoxy doesn't stick. We always use epoxy to glue down decks and haven't had a problem on several hundred decks in over 10 years.
We also sometimes will super glue pieces of tongue depressors to the plans to hold the in position while the epoxy sets. We use the non-permanent method here and usually sand these off to avoid any damage to the teak surface.
Once you are in the rhythm you can actually glue down several planks at one go. Once you have planks glued down you then go to the other side o the boat and proceed there. We work mostly in south FL and we use fast epoxy so we can usually do 2 and sometimes three sets a day on each side o the boat.
The other method is to build the to a pattern upside down on a bench and then glue on a plywood or fiberglass
skin to the bottom to hold the spring in the planks. The panels
are then glued to the sub deck.
Sprung decks will cost about a third more than a straight laid deck because o the additional labor involved.
Hope this was clear enough and is o some value. David
