Description
Jeffery's No.2, Black Marine Glue. This traditional product has been the premier choice for deck seaming for decades. Its fine pouring qualities allow it to be used for the smallest seams and once cured it adheres tenaciously to the seam, will not crack and remains flexible for many years.
Instructions for Melting and Applying
Break the glue into small pieces and put in a clean melting pot to three-quarters full, and place over heat source. Melt glue slowly, giving occasionally stirring until it flows freely, which will be about 200'C Care must be taken during the melting process, as prolonged overheating will damage certain qualities of the glue. The caulking must be hammered well down into the seams, which must be free from dust, grease, etc. which may prevent adhesion. Due to the expansion and contraction of timber and confirmed by practical experience we would suggest the following seam dimensions as being the minimum necessary to give a trouble free and waterproof deck.
Timber Width of planks Width of seams Depth of seams
Teak 50mm 2.4mm 9.6mm
Teak 75mm 6.5mm 12.5mm
Softwoods 50mm 2.4mm 9.6mm
Softwoods 75mm 6.5mm 12.5mm
Two applications of glue should be made the first coming level with the top of the seam. The first application will release a mass of bubbles of steam and air into the seam,which will rise to the top of the glue but will not all be released owing to the chilling of the surface. The second application will then reheat the top of the glue, allowing the bubbles to float out into the bead, which will later be scraped off and discarded.
The glue is available in 12.5 kg packs and 25 kg tins.
