A method for insulating an object with a protective coating under unfavorable conditions of, for example, high humidity, without separation or running of the binding material. The method provides for making a coating consisting of mineral fibers and a binder which includes one or more alkali silicates as well as one or more organic polymers for silicon dioxide. This binder and the mineral fibers are applied to the object together with a hardener for the binder, at the time of application to the object. The invention further describes an apparatus for simultaneous spray application of fibers, binder and hardener to the object to be protected.

A method for spray application of a protective coating to an object comprising spraying the coating onto the object, said coating being a mixture of mineral fibers and a binding material consisting of a solution of at least one alkali silicate, at least and at least one water-soluble and alkali-resi

A method for spray application of a protective coating to an object comprising spraying the coating onto the object, said coating being a mixture of mineral fibers and a binding material consisting of a solution of at least one alkali silicate, at least and at least one water-soluble and alkali-resistant organic polymer, wherein a hardener for hardening said alkali silicate binding material is added to said coating by independently conveying said hardener in the form of a solution to a spray nozzle which independently projects said mixture and said hardener towards the substrate being treated.
