Compliance Statement
Scope of Use
Osmo Anti-Slip Decking Oil
(430) is a clear, slip-resistant top-coat oil for exterior timber decking,
steps and walkways where enhanced underfoot grip is required - decks, pool
surrounds, ramps and stair treads in Bangkirai, Massaranduba, Garapa, Larch, Douglas
Fir, Pine and similar woods, on smooth, ribbed or grooved boards. Specify it as
the top coat over a pigmented Osmo Decking-Oil base coat, which provides the
colour and UV protection; 430 is not a stand-alone finish and must not be used
over clear Decking-Oil 007 Teak.
New Zealand Building Code (NZBC)
The product will, if employed in accordance with the supplier's installation and maintenance requirements, assist with meeting the following provisions of the building code:
Notes
Osmo's Anti Slip Decking Oil has been tested in NZ by Opus Laboratories for its anti slip effectiveness. When applied correctly, the results achieved a P4 rating with an SRV of 49. A copy of the test certificate can be supplied upon request.
Evidence
The product meets the requirements set out in the following documents, or relevant parts of cited standards within the documents:
Osmo Anti-Slip Decking Oil
(430) is a clear, slip-resistant top-coat oil for exterior timber decking,
stairs and walkways, applied over a pigmented Osmo Decking-Oil base coat. Pine
decking finished with Anti-Slip Decking Oil 430 was slip-resistance tested to
AS 4586:2013 (wet pendulum method, Four-S slider) by WSP Opus for Osmo NZ,
achieving a mean wet pendulum (BPN) value of 49 and a classification of P4,
with a mean coefficient of friction of 0.52. The finished surface is therefore
expected to contribute to compliance with NZBC Clause D1 (Access routes), which
requires walking surfaces to have adequate slip resistance, including external
and wet pedestrian areas. Slip resistance depends on correct application, wear
and cleaning. Test certificate available on request.
Design requirements
Osmo Anti-Slip Decking
Oil (430) is a clear, slip-resistant top-coat oil for exterior timber decking,
steps and walkways where enhanced underfoot grip is required - decks, pool
surrounds, ramps and stair treads in Bangkirai, Massaranduba, Garapa, Larch, Douglas
Fir, Pine and similar woods, on smooth, ribbed or grooved boards. Specify it as
the top coat over a pigmented Osmo Decking-Oil base coat, which provides the
colour and UV protection; 430 is not a stand-alone finish and must not be used
over clear Decking-Oil 007 Teak. A compressed organic non-slip additive
provides slip resistance (tested to AS 4586:2013 - see the compliance
statement), and the coating carries film protection against mould, algae and
fungal growth. Design the base colour to suit the timber species and setting.
For interior slip-resistant floors and stairs, specify Osmo Polyx-Oil Anti-Slip
instead.
Installation requirements
Apply to clean, dry
exterior timber that has weathered sufficiently (resinous softwoods and dense
hardwoods must weather before the first coat) and is free of old coatings, dirt
and mill glaze; clean and de-grey beforehand with Osmo Wood Reviver Power-Gel
or Decking Cleaner as needed. Apply the system in two stages: first a pigmented
Osmo Decking-Oil base coat on raw wood at approx. 35-45 ml/m2, left to dry ~12
hours; then the Anti-Slip Decking Oil top coat at approx. 35-45 ml/m2 (approx.
24 m2/L). Stir 430 thoroughly and regularly during use to keep the non-slip
additive evenly suspended, and apply thinly and evenly along the grain by brush
or roller. Recoatable after ~12 hours; ventilate and protect from rain until
dry. Do not apply over Decking-Oil 007 Teak. Caution: oil-soaked cloths can
self-ignite - dry flat or store in a sealed metal container.
Maintenance requirements
Keep decking clean to
preserve both appearance and slip resistance: regularly remove leaves, dirt and
organic debris and wash with water and Osmo Decking Cleaner, working along the
grain; avoid aggressive or film-forming cleaners that could reduce grip. Where
the surface has greyed or the finish has worn, clean and de-grey with Osmo Wood
Reviver Power-Gel, allow to dry, then re-oil. Osmo Decking-Oil systems refresh
without sanding or a primer - normally one maintenance coat of pigmented
Decking-Oil followed by a coat of Anti-Slip Decking Oil restores colour,
protection and slip resistance. Whenever the surface is recoated, re-establish
the Anti-Slip top coat so slip resistance is maintained. Frequency depends on
exposure, wear and foot traffic - typically once a year on well-used or
weather-exposed decks.
