HYDRO ornamental effect

• Sand the selected substrate material well (such as FPY or MDF priming foil, or melamine resin foil). We recommend sanding with 150 - 240 grit. Depending on the desired effect, we also recommend using an initial filler on bare MDF surfaces and edges to achieve an homogenous base.  
• The drying time for this primer coat is ideally overnight at 20 °C room temperature. Then sand with 280 - 400 grit directly before further coating.  
• Next apply HYDRO COOL-COLOR HB 65285-(colour tone), adding 25 - 30 % of HYDRO Ornamental additive HZ 78 depending on the desired ornamental structure. Mix in this additive with a stirring stick until it is homogeneously distributed. Please ensure that no air is incorporated into the lacquer if you use an electric mixer; therefore set it to slow (exception: see under hints and tips)!  
• Apply 120 - 150 g/m² of this prepared colour lacquer mixture to the substrate material using an (over) pressure cup gun.  
• Subject to the size of the surface to be coated, the desired ornamental effect can be worked in using a brush or other tool after 5 - 10 minutes of initial drying at 20 °C room temperature.  
• Depending on the level to which the ornamentation is raised, allow the surface to dry at least overnight (around 16 h), preferably 48 h / 20 °C room temperature.  
• The ornamentation can then be appropriately accentuated using a wiping stain, such as Hesse HYDRO Wiping stain TW 4130-7040.  
• Allow the surface to dry for around 1 - 2 h.  
• Then sand for effect and remove the sanding dust accordingly.  
• Finally finish the surface either using Hesse COOL-TOP HE 6509x(gloss level) or Hesse HYDRO-PUR PRIMO HDE 5400x(gloss level), mixing ratio 10 : 1 with HDR 5091.

Information on creative effects

• By intentionally stirring air into the Pigment filler (fast stirring with an electric mixer) you can achieve surfaces that dry out to be bubbly/foamy. When these surfaces are sanded you can create crater-like depressions. These are appropriately emphasised by the stain.  
• The base tone conforms to the colour tone of the colour lacquer used. This can be further nuanced if necessary by adding Hesse HYDRO pigment concentrates (such as HFM 985, black). Maximum added quantity 5 %.  
• Further variations result from using a different colour of Wiping stain.  
• Additional background structures can be developed using different sanding methods (hand sanding with sandpaper, sponge, etc. or machine sanding with an orbital sander, or similar).  
• Different patina effects can also be achieved with effect accentuation of the stain using a gauze rag or a sponge.  

Please observe the latest technical information and the material safety data sheets for the stated individual products.

Particular instructions

• Please follow the precise specifications for addition of hardeners and any other additives as well as the drying times. Ensure careful stirring or respectively mixing in of all necessary components.
• HYDRO lacquered surfaces should be freshly sanded on the next day before the finish is applied to avoid adhesion problems.
• Each prepared surface is a unique piece!  Please conduct a sample coating under real conditions.
