The invention relates to a microemulsion comprising water in an amount of 1-30 w %; sodium or potassium oleate, Na/K salts of tall oil fatty acid, and/or Na/K salts of C16-C18 saturated or unsaturated fatty acids in an amount of 10-40 w %; oleic acid, tall oil fatty acid, or C16-C18 saturated or unsaturated fatty acids in an amount of 2-40 w %; ethanol in an amount of 0-40 w %; glycerol in an amount of 5-40 w %; and liquid hydrocarbon(s) in an amount of 5-40 w %, up to a maximum or total of components parts of 100 w %. Moreover, methods of manufacture and uses of the microemulsion are disclosed.

An extrusion system (100) includes at least one sensor (102, 104) to detect localized presence of oil (701) on an exterior surface (715) or skin of wet extrudate material (714 e.g., ceramic material having a honeycomb cross-sectional shape), and at least one infrared emitting device (106, 108) configured to impinge infrared emissions on at least a portion of the exterior surface responsive to one or more sensor signals. Localized impingement of infrared emissions may reduce presence of oil streaks (701) without undue differential drying of the extrudate skin (715), and avoid surface fissures that would otherwise result in fired ceramic bodies. Separately controllable infrared emitters (502), or at least one controllable infrared blocking or redirecting element (603), may be used to impinge infrared emissions on selected areas. A humidification section (120) arranged downstream of infrared emitters (106, 108) may be used to at least partially rehydrate the wet extrudate material, if necessary.

A material restoration system disclosed herein. The material restoration system includes a first composition (referred to herein as Composition A) and a second composition (referred to herein as Composition B). Composition A is a cleaning, stain-lifting, and rejuvenation product which is permeable into many construction materials (i.e. concrete). Composition A is capable of removing surface contaminants, including salt, surface rust, calcification and hard water byproducts, oxidation, and efflorescence. Composition A permeates into the material and acts to lift stains. Composition B is a surface applicant and can be used to resurface construction materials (particularly concrete) or fill voids and damage broken construction materials. Composition B has strong bonding properties and is able to provide structural benefits when used to fill cracks and chips.
