HMK S748 Extra Color Enhancing and UV Protection
Ultimate Color Stability keeping Ctone Colors looking Great for up to 5-Years
HMK® S748 is a ready to use, solvent-based oleophobic special impregnator with color
enhancing properties for use on natural stones, artificial stones and terrazzo surfaces that reduces the
penetration of water, dirt, oil and grease. HMK® S748 is suitable for interior and exterior use.
Properties: HMK® S748 reduces the penetration of water, dirt, oil and grease into surfaces. As a result, it greatly reduces staining and also facilitates dirt removal and regular cleaning. The colour and structure of the surface are significantly accentuated due to its colour enhancing properties. The water, oil and grease repellent properties depend on the absorbency of the respective surface. The repelling and colour enhancing effect is increased by the amount of HMK® S748 the surface can absorb; the more that is absorbed the better is the effect. Acid-sensitive natural stone surfaces, e.g. polished marble and limestone, may still be adversely affected by contact with wine, orange juice, cola etc., however, to a considerably lesser extent than untreated surfaces, making it significantly easier to remove any dull areas. HMK® S748 does not yellow with age. The water-vapour diffusion properties of the material are only slightly affected. Once dry the residual material is not hazardous to health and is approved for use with foodstuffs by the LFGB (German Food and Feed Code).
HMK® S748 is suitable for all absorbent natural and artificial stones, such as polished, honed or textured marble, limestone, travertine, Solnhofen slabs, granite, gneiss, terrazzo, agglomerate marble etc. Suitable for interior and exterior use. Non-absorbent surfaces, such as glazed tiles and the like, cannot be treated with this product.
Durability: The durability of the product once applied depends on the absorbency, saturation and uses of the surface, the amount of traffic and the implementation of a suitable care, maintenance and cleaning program. HMK® S748 generally lasts several years and can be easily renewed if necessary.
Application: When treating freshly laid areas allow sufficient time for drying to permit moisture to escape from the surface and substructure (max. residual moisture 2-4%). If under floor heating exists, make sure it is turned off at least two days before application to allow the surface to cool. Ensure the surface is of ambient temperature, clean, dry, free of stains and absorbent prior to beginning treatment.
To clean the area thoroughly before treatment use HMK® R55 Intensive Cleaner -acid free-.
After the surface has been thoroughly cleaned allow it to dry for at least 1 to 2 days for the moisture from the cleaning solution to escape the surface (max. residual moisture 2-4%). Important: Test the product in an inconspicuous area to determine suitability and coverage.
Apply HMK® S748 generously and evenly on the naturally cooled, clean, dry and absorbent surface using a natural bristle paintbrush or a roller with short fibres. Leave on for 20-30 minutes, with sufficient HMK® S748 on the surface to keep it wet. Afterwards, immediately and completely remove excess HMK® S748 with a plain white paper towel and rub the surface dry. Dark marks or streaks may occur if excess material is not removed adequately.
Repeat treatment for very absorbent surfaces after approx. 24 hours.
Care recommendation: We recommend using HMK® P324 Liquid Stone Soap -no rinse- for regular cleaning, as well as occasionally using HMK® P319 Marble and Granite Polish (Interior use) to refresh the shine on polished indoor surfaces.
Important: Do not apply to rubber, plastics, lacquered or varnished surfaces, waxed or stained wood and solvent intolerant materials. Protect surfaces that are not to be treated, such as walls, glass, furnishings, etc.
Working temperature: The ideal working temperature of the surface to be treated is between +50°F and +80°F. Do not apply in direct sunlight..
Drying time: Depending on room temperature and ventilation approx. 10 to 12 hours. Do not walk on the treated area during this time. Protect the surface from rain and humidity for 72 hours. The resistance to oil and water is developed within 72 hours.
Removal: HMK® S748 can not be removed chemically after polymerization.
Pearling effect: A pearling effect can temporarily occur after applying HMK® S748. This effect, however, should disappear on its own and should not used to assess the effectiveness, protective characteristics or durability of the product.
Coverage: Approx. 50 to 220 sq.ft/litre, depending on material and surface treatment.
Packaging: 12 x 1L tins per box; 2 x 5L tins per box
