Remove grease, wax, cement slurry and all other adhesion-reducing substances. Sand the substrate. After that, the substrates are primed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e\u003cbr\u003e\nWear appropriate protective clothing during application, such as: safety glasses, disposable gloves, and respiratory masks if necessary. Apply the primer using a squeegee, paint roller or airless sprayer. No further dilution is necessary when using an airless sprayer. Apply the material quickly and evenly without puddles on the substrate. Depending on the flatness and porosity of the substrate, 100-300g\/sqm is required for priming. Very absorbent substrates must be primed again. We recommend sanding substrates that will not be further processed on the same day with BK-705 quartz sand.\u003c\/p\u003e\n","brand":"BEKATEQ","offers":[{"title":"1L","offer_id":55311812657486,"sku":"6370001","price":33.0,"currency_code":"CHF","in_stock":true},{"title":"2x 1L","offer_id":55311812886862,"sku":"6370002","price":55.0,"currency_code":"CHF","in_stock":true},{"title":"3x 1L","offer_id":55311812985166,"sku":"6370003","price":74.0,"currency_code":"CHF","in_stock":true},{"title":"5x 1L","offer_id":55311813083470,"sku":"6370005","price":116.0,"currency_code":"CHF","in_stock":true},{"title":"10x 1L","offer_id":55311813214542,"sku":"6370010","price":215.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/9131\/9328\/files\/bk-637pu02dose-kleinjpg-433189.jpg?v=1793794577","url":"https:\/\/www.bekateq.de\/en-ch\/products\/bk-637pu-1k-pu-grundierung","provider":"BEKATEQ","version":"1.0","type":"link"}
