Hi guys, Everything went according to plan ...... first class service.
Very effective product. Easy to apply
I have used Boracol for over twenty years as an annual treatment for the teak on my Yacht. I have just refurbished a teak bench that is over 40 years old with excellent results.
It works superbly. Fantastic product. Will be getting more.
Was hoping it would remove the discolourations in the Teak, but unfortunately it has not done so

Wash to remove all dirt and coatings (some manufacturers of Teak Decking do not recommend pressure washing, please check with the manufacturer beforehand). Allow the surface to dry out until the surface is just damp.
Apply one coat of Boracol 5Rh, by brush or spray, to refusal (visibly wet on the surface, but not running off). Avoid any run off to other parts and from the boat.
Allow the surface to dry out until just damp again. Apply a second coat of Boracol 5Rh to refusal.
Remove any thick layers of organic growth with a suitable brush or scraper.
Some species of lichens are resistant to treatment due to their impervious surface. To optimise the effect of the biocide solution it is advisable to abrade the face of such growths prior to treatment (e.g. by wire brush).
Apply ACS Boracol 5Rh under dry conditions using a coarse spray to saturate the surface. Allow to dry thoroughly and apply a second coat if required.
Apply to refusal as coverage will be governed by the porosity and type of substrate i.e. wood, brickwork, concrete.
ACS Boracol 5Rh is suitable for application on roofs, walls timbers, paths and patios.
Clean all wooden surfaces using a brush or vacuum.
Cover electrical installations, water tanks, stored goods and isolate adjacent areas notrequiring treatment. Lift floorboards as required and clean out debris.
ACS Boracol 5Rh can be applied to timbers by brush or coarse spray.
During spray application some respiratory / face protection will normally be required.
Under normal circumstances one coat will be sufficient, however ensure that all accessible wood surfaces are thoroughly wetted out. Any surface which rapidly absorbs ACS Boracol 5Rh should be sprayed again at the time.
In the case of timber sub-floor areas, the base of the structural walls, sleeper walls and oversite (solum) should be treated with ACS Boracol 5Rh.
Apply a second coat of ACS Boracol 5Rh after one to eight hours where there is severe fungal attack or the presence of House Longhorn beetle (Hylotropes Bajulus).
Provide adequate ventilation following treatments and maintain as long as possible after re-occupation.
Please note that any metallic surfaces (such as copper pipes) should be isolated from the treatment area as the boron salts may cause a chemical reaction causing surface pitting of the metal.
By Brush: 1 litre per 2m² to 4m² of surface.
By Spray: 1 litre per 2m² to 4m² of surface.
As long as timbers are dry, re-occupation can take place 48 hours after treatments are completed.
Floor coverings should not be laid for at least 72 hours (or longer for certain impermeable or other floor materials, e.g. vinyls, foam-backed carpets etc.) In all cases, use lining papers to protect coverings from direct contact with timbers.
Treated timbers can be over coated when dry with a range of decorative / protective paints etc. (to ensure compatibility check a small area first).
