Outdoor Chalkboards and
Weatherproof Blackboard Signs
Outdoor chalkboards use exterior-grade HPL (High-Pressure Laminate) or EOT surfaces that repel moisture, resist UV fading, and wipe clean without ghosting after outdoor exposure. Must be used with waterproof liquid chalk pens, as traditional stick chalk washes off immediately in rain. Treated solid wood frames resist rot and swelling in wet weather. Available wall-mounted with fixing kits, as portable A-boards for pavement placement, and in shaped panels. Sizes A4 to A0.
An indoor chalkboard left outside will absorb moisture, warp, grow mould on the wood frame, and have the chalk wash away in the first shower. Outdoor chalkboards are constructed from different materials throughout: non-porous HPL surface panels that repel water rather than absorbing it, wood treated with weather-resistant stain and marine-grade varnish, and UV-stabilised surface coatings that maintain the deep black colour through full seasonal sun exposure.
Our most popular outdoor chalkboards include the A1 wall-mounted outdoor chalkboard for pub and restaurant entrance walls, the black wooden outdoor chalk A-board for pavement placement, and the heavyweight outdoor chalk A-board for high-traffic hospitality positions.
