【施工前】 約800ｍ2の施工面積。 今回の仕様は【シールハードFGS+SSP100目地充填工事】 光沢ある床に目地の充填も請け負いました。 この組み合わせを大変好評がよく、メンテナンスもさらに容易になります。
-
【目地充填】 アメリカ生まれのポリユリア性の樹脂。 微弾性があり、コンクリートの収縮に追従し目地が開くことがない絶妙な硬度。 目地を埋めることでゴミつまり、̚角欠けがなくなり運用が楽になります。
-
【目地充填後】 柱周りも目地充填しました。 カッター目地+目地充填を行う事でコンクリート特有のクラック軽減にもつながり、お勧めの仕様です。 アメリカではスタンダードな仕様になっております。
-
【研磨工程】 目地充填後に、シールハード工事スタートしました。 じっくり、丁寧に研磨工程を行い、バキュームで汚水を吸いとります。
