Guidance from job tag (Japanese)
入職にあたって、特に学歴や資格は必要とされない。必要な技能は、現場で働きながら身に付けていくのが一般的である。技能を習得するのに必要な年数は防水層の種別や工法の種別によって異なるが、早ければ2～3年、遅くても5年程度で一応の仕事はできるようになる。
　入職後一定の実務経験を積んだ後に、厚生労働省の定める技能検定の「防水施工技能士」の資格を取得すると、技術の証明となる。
　入職後に技能の向上を図り、更に経験を積むことによって、自営業者として独立、開業の可能性もある。
　なお、防水工事の際にトルエンやキシレンなどの人体に有害な物質を含むウレタン溶剤などを用いることから、「危険物取扱者」、「有機溶剤作業主任者」などの資格を持っていることが望ましい。
