Marine decking
US 3863417 A
Marine decking comprises a panel of wood blocks embedded in a bedding composition with a rubbery grouting composition between the blocks. The decking is laid by spreading the bedding composition, before the composition has set embedding the panel therein, and after setting applying the grouting composition.

PATENTEB F 4W5 sum 20F 2 MARINE DECKING The invention relates to external marine decking and a method of laying it.

Marine decking according to the invention comprises a bedding composition having embedded therein a panel of wood blocks held together in mutually spaced relationship, the blocks having dovetail grooves along lower edges, and a rubbery grouting composition between the blocks. The decking may include a levelling latex underlay.

The blocks may be held together by a sized textile mesh, preferably of cotton, the mesh preferably being from one eighth to three eighths inch (about 3 to 9 mm) across, preferably one quarter inch (about 6 mm) square. Alternatively, the blocks are preferably held together by staples on the under side, the staples generally extending laterally at the middle and ends of each block, giving a total of eight staples entering each block. Additional longitudinal rigidity may be provided by staples between the ends of adjacent blocks at the edges of the panel. Alternatively again, the blocks may be held together in a panel initially by a sheet material such as paper adhering to the upper surface. In this case, the blocks are held together in spaced relationship in the finished decking by the bedding and grouting compositions after the paper has been removed. Each panel is preferably about 2 feet (60 cm) by about 18 inches (45 cm).

The wood blocks are preferably of hard wood such as teak, preferably of square or approximately square cross-section, and several times as long as they are across. The preferred dimensions are /2 inches (about 140 mm) long X "/8 inch (about 22 mm) wide X inch (about 19 mm) thick. The preferred spacing between adjacent blocks is one eighth inch (about 3 mm). In order to improve adhesion, a longitudinal groove may be cut along the middle of the underside of each block about as deep as the dovetail grooves, that is about one eighth inch (about 3 mm) wide and not more than three sixteenth inch (about 4.5 mm) deep, for example a saw cut.

The method of laying marine decking according to the invention comprises spreading bedding composition on the deck, before the composition has set, embedding therein a panel of wood blocks held together in mutually spaced relationship, the blocks having dovetail grooves along lower edges, and, after the bedding composition has set, applying a grouting composition between the blocks. I

Prior to laying, the deck should be clean and level. A levelling latex underlay may first be applied, generally over the whole area to be laid, and allowed to set before the bedding composition is spread. The bedding composition is generally spread over a small area at a time, and the embedding therein of the blocks coordinated therewith so that the composition does not set before the embedding. In the embedding, the bedding composition should pass up between the blocks and cooperate with the dovetail grooves to retain the blocks in position. After the bedding composition has set, the grouting composition is applied, and after the grouting composition has set, the decking should be finished by sanding.

The panels may be made by mounting the blocks on the mesh by means of an adhesive such as a waterbased polyvinyl acetate. In the preferred alternative method, the blocks are stapled together after arrangement in a jig with the undersides uppermost in the desired spaced relationship, for example by means of a hydraulically operated bank of staplers. In the other method, the blocks are arranged in the jig with the upper surface uppermost, and a sheet of material is made to adhere to them.

The bedding composition, grouting composition and latex underlay may each be such as would naturally be adopted by a man skilled in the appropriate art. By way of example only, we mention that the bedding composition may consist of:

natural rubber latex. fully stabilized. 30% by wci ht solids. modified with anti-foam and the grouting composition may consist of: Y carboxylated styrene/butadiene rubber latex, 40% by weight solids. In place of the styrene/butadiene latex, other synthetic rubber latices such as those of neoprene or an acrylic or vinyl copolymer.

The invention is illustrated by way of example in the drawings of which:

FIG. 1 shows a cut-away section of external marine decking;

FIG. 2 is a perspective view of the underside of a small panel of teak blocks held together by staples to illustrate the manner of use of a full size panel in the preferred alternative form of decking according to the invention.

In FIG. 1 a metal external marine deck 1, with a weld 2, has a levelling latex underlay 3 thereon. On the underlay 3, there is a bedding composition 4 having embedded therein a sized cotton textile mesh 5 with teak blocks 6 secured thereto by means of adhesive. The blocks 6 have a dovetail groove 7 along each lower edge to assist in retention by the composition 4. A rubbery grouting composition 8 is between the upper parts of adjacent blocks. This decking has much of the good weathering and wear characteristics and attractive appearance of solid teak decking.

In FIG. 2, the blocks 6 are held together by staples l0, and a longitudinal groove or saw cut 12 is shown on one block only for illustration. The staples 10.are all transverse except those at the edges of the panel.

What we claim is:

l. The method of laying marine decking on a deck area, comprising forming dovetail grooves along the lower edges of wood blocks, securing together a plurality of said wood blocks in mutually spaced relationship to form a panel, spreading a bedding composition on the deck area, pressing said panel of wood blocks into said bedding composition before the latter has set such that the bedding composition passes up between said wood blocks as said panel is pressed, allowing said bedding material to set such that the set bedding material cooperates with said dovetail grooves to retain said wood blocks on said deck area, and applying a grouting material between said wood blocks.

2. The method according to claim 1 including utilizing staples to secure said plurality of wood blocks to form said panel.

3. The method according to claim 1 including securing said plurality of spaced wood blocks to a sized textile mesh.
