Before applying, make sure the surface is clean and free from dust, rust, paint and grease. In the case of porous surfaces, it is advisable to moisten the material with water. For an 8-meter 6x6 mm joint, it is sufficient to use a putty cartridge.\u003c\/p\u003e\u003cp\u003e To apply, moisten the joint with water and spray an even layer of sealant. Next, immediately smooth with a damp putty knife. Leave to dry for at least 24 hours and then heat until the product is completely dry. In the exhaust pipes, apply a layer of sealant, insert a piece of glass cloth and cover again with sealant. Leave to dry for at least 24 hours and remove excess sealant immediately with water.\u003c\/p\u003e\u003cp\u003e It is recommended to remove wet stains with water. Dried residues can only be removed mechanically. It is important to avoid overheating the sealant during the drying process, as this may cause the sealant to crack and crumble. It is normal for a liquid layer to form on the sealant over time, but this does not affect the quality of the product.\u003c\/p\u003e\u003cp\u003e Drying time may vary depending on the type of surface, the amount of product used, the air temperature and humidity. It is recommended to use Bostik refractory mastic within 24 months of production to ensure maximum effectiveness.\u003c\/p\u003e","brand":"UHU BOSTIK SPA","offers":[{"title":"Default Title","offer_id":40852283981895,"sku":"024768","price":10.72,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0567\/0148\/5127\/files\/ec265347942276b7ce223acad8cdf695.jpg?v=1715025617","url":"https:\/\/www.iperbriko.com\/products\/bostik-refractory-sealant-for-fireplaces-and-stoves-530-gr-putty-d2025","provider":"Iperbriko","version":"1.0","type":"link"}
