sealing joints on a wood deck

joist

a joist is a horizontal structural member used in framing to span an open space, often between beams that subsequently transfer loads to vertical members. when incorporated into a floor framing system, joists serve to provide stiffness to the subfloor sheathing, allowing it to function as a horizontal diaphragm.joists are often doubled or tripled, placed side by side, where conditions warrant .

oakum

its main traditional applications were in shipbuilding, for caulking or packing the joints of timbers in wooden vessels and the deck planking of iron and steel ships; in plumbing, for sealing joints in cast iron pipe; and in log cabins for chinking. in ship caulking, it was forced between the seams using a hammer and a caulking iron, then sealed into place with hot pitch.

strapping

strapping can also be used in loops attached to holding locations on rail cars, skids, etc. joining methods. after the strap is tensioned, the strap is often sealed to itself. steel strap is sealed with a seal and notch joint, a seal and crimp, seal-less joint, or via welding. seals come in various shapes depending on the application; some can .

scarf joint

the scarf joint in wood in woodworking, there are two distinctly different categories of scarf, based on whether the joint has interlocking faces or not. a plain scarf is simply two flat planes meeting on an angle relative to the axis of the stock being joined, and depends entirely on adhesive and/or mechanical fasteners such as screws, nails, or bolts for all strength.

splice joint

a splice joint is a method of joining two members end to end in woodworking.the splice joint is used when the material being joined is not available in the length required. it is an alternative to other joints such as the butt joint and the scarf joint.splice joints are stronger than unenforced butt joints and have the potential to be stronger than a scarf joint.

coping joinery

coping or scribing is the woodworking technique of shaping the end of a moulding or frame component to neatly fit the contours of an abutting member. joining tubular members in metalworking is also referred to as a cope, or sometimes a 'fish mouth joint' or saddle joint.. most english-speaking countries outside the united states use the terms scribe and scribing.

sealant

history. sealants were first used in prehistory in the broadest sense as mud, grass and reeds to seal dwellings from the weather such as the daub in wattle and daub and thatching. natural sealants and adhesive-sealants included plant resins such as pine pitch and birch pitch, bitumen, wax, tar, natural gum, clay mud mortar, lime mortar,.
