A sealant for the remedial sealing of self-sealing coke oven doors, or ordinary coke oven doors sealed with a conventional lute, or for sealing spigot joints in off-gas pipe lines in coke oven installations comprises a mixture of from 25 to 45% of a latex, (preferably a PVA-based latex) from 10 to 25% water, from 25 to 45% of a particulate filler (preferably a talc) and from 5 to 15% of an inorganic fibre (preferably an asbestos fibre). At least 40% of the fibre should pass through a British standard 100-mesh sieve. The sealant may vary from a flowable to a putty or paste-like consistency and may be applied by spraying or trowelling as appropriate. If the inorganic fibre is not an asbestos the sealant may also include a proportion of a water soluble thickener to enhance the compatibility of the mixture.
