Key specifications include mfp535 of 50 lbs and mfp535-l of 55 lbs. It is the same exclusive mortar supplied with every Mason-Lite fireplace kit, so you can be confident it meets the strength and heat-resistance requirements of the system. Using the correct refractory mortar is essential for safety, and ordinary masonry mortar should never be substituted in a fireplace application.\u003c\/p\u003e\u003cp\u003eThe dry mix is supplied in a sealed bucket that stays easy to store and transport, then mixes with clean water on site for a smooth, workable consistency. Keep extra on hand for large projects, multiple fireboxes, firebrick panels, masonry chimney sections or repairs and touch-ups. It bonds pre-cast blocks tightly and cures to a strong, heat-resistant joint that stands up to years of fires. Choosing genuine Mason-Lite parts keeps your installation consistent with the manufacturer's tested system, protecting performance, appearance and long-term reliability.\u003c\/p\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e(1) Refractory Mortar\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHigh-temperature refractory formula\u003c\/li\u003e\n\u003cli\u003eSame mortar supplied with Mason-Lite kits\u003c\/li\u003e\n\u003cli\u003eFor fireboxes, firebrick and masonry chimneys\u003c\/li\u003e\n\u003cli\u003eDry mix in a sealed bucket\u003c\/li\u003e\n\u003cli\u003eMixes on site with clean water\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eMason-Lite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eCategory\u003c\/th\u003e\n\u003ctd\u003eMortar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003eLimited Lifetime Warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eMade In\u003c\/th\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eWeight\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMFP535\u003c\/td\u003e\n\u003ctd\u003e50 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMFP535-L\u003c\/td\u003e\n\u003ctd\u003e55 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eDocuments \u0026amp; Files\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0772\/9646\/8151\/files\/masonry-accessories-brochure-web.pdf\" target=\"_blank\" rel=\"noopener\"\u003eAccessories Brochure\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Mason-Lite","offers":[{"title":"Default Title","offer_id":58009251643575,"sku":"MFP535","price":190.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/9646\/8151\/files\/MFP535_1.webp?v=1793180509","url":"https:\/\/www.efireplacedirect.com\/products\/mason-lite-refractory-mortar","provider":"efireplacedirect","version":"1.0","type":"link"}
