Bauder AP3 Protection Board is a lightweight, pre-fabricated board composed of fibres saturated with a minimum of 75% bitumen. It offers impact and abrasion resistance, safeguarding the waterproofing system and is suitable for both horizontal and vertical applications. The board has smooth surfaces on both sides, covered with a polyethylene film. Modified bitumen membranes can be applied using torching, mopping, or cold adhesive directly onto the board.

Bauder AP3 Protection Board provides both temporary and permanent protection for waterproofing applications on parking garage decks, terraces, roadways, green roofs, planters, and promenade decks. It protects horizontal and vertical waterproofing membranes from damage due to site traffic, mechanical impacts, and ground settlement.

For temporary protection, the boards can be removed later if needed to accommodate subsequent trades.
