Expert Verdict Reviewed by the SuperArbor Pro Desk

Start BUR jobs with a properly attached base sheet, keeping laps shingle-lapped in the direction of water flow. On decks that require mechanical attachment, fasten at the specified pattern to resist wind uplift before mopping plies. Roll out material fully and let it relax before adhering to avoid buckles.

Mopping asphalt is a hot-work hazard; follow hot asphalt handling practices, wear protective gear and keep flammables clear of the kettle and mop cart.
