Tips & Tricks: IRSA Design-Colour Oil
- Invariably a test staining must be carried out (with newly laid parquet flooring on the sample piece of the original parquet) with the desired varnish or oil system (only use IRSA HP-Oil High-Protection). Wood is a natural product and according to the material content and growing area can have differing reactions and show colour discrepancies.
- Show the customer as large a surface area as possible (the stained large surface can look different to a small wooden sample which was polished manually) and get the desired colour confirmed in writing. Make it clear to the customer in writing that manual staining is a skilled profession, during which subtle colour graduations can occur.
- The surface must show an evenness in polish (even at the edge areas; i.e. the surface must be completely sanded with the same sanding grit (e.g. 120 grit on oak), so that the colour primer does not soak in at varying degrees and cause patches. On surfaces which soak up less, like bamboo or olive wood parquet, check whether a coarser end sanding will bring better results.
- Ensure that all sanding dust has been completely removed.
- The coloured IRSA Design Colour Oil is always rubbed into the pores in the wood without leaving any residue. Any oil remains will dry on leaving a shiny finish and will partially deepen the colour of the wood.
- Several workers should always work on very large areas so that the time the oil takes to seep in on a freshly oiled surface does not exceed 40 minutes.
- A second coat of oil is then applied, either when the surface still absorbs oil after the first oil application dried over night, or if the surface is still rough because of the type of wood. Industrial and/or upright segment parquet generally requires a second coat of oil.
For the second coat of oil use the appropriate coloured IRSA Design Colour Oil or the additionally protective IRSA HP-Oil colourless.
- When staining in summer avoid direct sunlight on the floor; the floor temperature should lie between minimum +18° C, maximum +25° C, and the humidity be approximately 55 % .
The re-treatment of coloured oiled surfaces
It is unavoidable that coloured oiled wooden floors become unequally worn during the course of use, so that they should be re-oiled in good time with the appropriate coloured IRSA Design Colour Oil, as in comparison to the colourless oiled surfaces. Before re-oiling with IRSA Design Colour Oil the surface should be thoroughly cleaned with IRSA Base Cleaner G88 and after the floor is dry it should simply be given a new thin coat of oil using the suitable IRSA Design Colour Oil and then the surface polished as described above. If the surface is cared for correctly, re-oiling can be delayed.
Special Care Instructions for coloured oiled floors can be received from IRSA.
All surfaces stained with IRSA Design Colour Oil can, if a higher degree of gloss or an additional protection against penetration by liquid (e.g. in bars or bathrooms) is required, be re-waxed with IRSA Natura Hard Wax. In doing so, one can choose from the colourless, white or the light and/or dark brown IRSA Natura Hard Wax depending on the stain of the floor.
If re-waxing is not desired, then one should use IRSA Care Oil (only available in colourless) with the appropriate pre-oiled cloths for continued maintenance and cleaning. For more stubborn dirt and for mop cleaning use IRSA Soap Cleaner. For white oiled and/or white oiled and white waxed surfaces the best cleaner is the IRSA Soap Cleaner white for daily mop cleaning.
The appropriate care instructions, which are available free of charge from the manufacturer IRSA should be enclosed with the price offer and the invoice. Please also pay attention to the label as well as the technical data sheet for IRSA Basic Color and the sealants.
