This versatile primer is ideal for automotive refinishing, industrial applications, and custom projects where a durable, smooth base coat is required. Its flexible acrylic formulation ensures compatibility with most topcoats, making it a reliable choice for achieving professional-quality finishes.\u003cbr\u003eSurface preparation is simplified with this primer’s excellent adhesion capabilities, which help ensure a strong bond to diverse materials. The high-build nature allows for effective filling of surface imperfections and minor imperfections, reducing the need for extensive bodywork. The primer dries in approximately one hour and can be recoated after 5 to 10 minutes of flash time, allowing for efficient application workflows. Applying 2 to 3 medium wet coats will typically cover around 11 square feet at a 2 mil dry film thickness, supporting both small repairs and larger projects. This primer is easy to sand, making it straightforward to achieve a smooth surface before applying the final topcoat.\u003cbr\u003eDesigned for ease of use, the aerosol format provides precise application and minimizes overspray, making it suitable for both professional body shops and DIY enthusiasts. Whether working on metal or plastic surfaces, the SEM High-Build Primer Surfacer provides a reliable foundation for high-quality finishing results. Its compatibility with most refinish materials ensures a seamless layering process, ultimately delivering a durable, professional-looking finish that meets industry standards.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eProvides superior adhesion for multiple substrates including metal and plastic\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eExcellent filling properties for surface imperfections\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eWorks on steel, aluminum, fiberglass, and plastics\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEasy to sand for a smooth finish\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with most topcoats and refinish materials\u003c\/li\u003e\u003c\/ul\u003e","brand":"SEM","offers":[{"title":"Default Title","offer_id":44434496389162,"sku":"109313","price":20.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/109313XL.jpg?v=1780914700","url":"https:\/\/atticusgoods.com\/products\/sem-high-build-primer-surfacer-20oz-aerosol-can-black-for-automotive-and-industrial-applications","provider":"Atticus Goods","version":"1.0","type":"link"}
