OSB 3 Tongue & Groove Flooring Board Key Features:
OSB3 board – also known as sterling board – is an extremely versatile engineered wood sheet material that promises quality results.
Strips and softwood flakes of wood are layered with an adhesive resin and then hot-pressed into a panel. This strength lends itself to OSB3's performative superiority over its sister board OSB2.
While Class 2 OSB sheets can only be used for non-load bearing applications in dry conditions, OSB3 is an ideal solution for structural, load-bearing uses in humid conditions in housing applications. The boards are edge-coated with a proprietary water-resistant sealer to lessen the chances of edge swelling.

OSB Board for Humid Conditions
Thanks to the resin binders and wax involved in its manufacturing process, OSB sheet material is tolerant of both moisture and humidity. While the OSB2 board is only suitable for dry conditions, OSB3 board can withstand more challenging conditions. Despite this being the case, it is always a good idea to add further weather protection if you are planning to use it for permanent outdoor use.
You can do this by adding weather-proof exterior paint. Follow the exterior paint with a wood waterproofing sealant. Allow 12-14 hours for it to dry before installing it - you can add a second coat if required.
