DEC 21

DEC 21 is a mix of organic solvents and wetting agents that is used to strip wax deep down from surfaces. It is able to remove old residues of synthetic and organic wax, sealants and water- or solvent-based treatments, impregnators, greasy or oily surface stains, or deep, long-standing oily dirt. DEC 21 is recommended to remove previous coats of solvent-based products or to completely strip wax from flooring to restore its original appearance. Although it is extremely effective when it comes to removing dirt, wax, and previous treatments, it will not damage surfaces or change their appearance.

DEC 21 is a product that as well as being suitable for use on its own, is often used together with one of Faber’s strong alkaline-based degreasers, such as COTTOSOLV or DECERA/P, for a full, deep wax removing action, known as “double wax stripping” Double wax stripping is an operation developed especially to remove any organic compound or residue from a surface, such as, wax, resin or previous treatments, for example, or even layers or stains of oily dirt.

Preparing and cleaning the surface

Before proceeding to wash the surface with DEC 21, it is advisable to clean away any surface residues, such as dust, debris, and coarse dirt, using a broom or a vacuum cleaner,
We recommend treating small areas of the surface at a time. The size of the area to be treated individually should be decided according to the absorption level of the material. When applying to highly absorbent surfaces, such as terracotta, it is necessary to work on an area of no more than 4-5 square meters, to ensure that the product does not penetrate the surface completely, which would prevent it from carrying out its function. When applying to low-absorption surfaces the treated area may be larger, according to the requirements and the capability of the operator.



• DEC 21 is ready to use.
• Apply the undiluted product to the surface, covering the whole area being cleaned and distributing it evenly with a single-disc machine or large brush.
• Let the product work for about 10-15 minutes, helping its dissolving action by passing over with a single-disc machine or large brush at more or less regular time intervals, according to the stubbornness of the dirt. This will boost the dissolving action of the product and give you better results.
• When applied to particularly absorbent surfaces, while working with the product, it may be necessary to pour some more onto the surface, to compensate for the product absorbed by the material. For the best possible results, the surface needs to be completely covered by a fine layer of product throughout the treatment.
• This operation can be carried out using a more or less abrasive disc or brush, to be selected according to the type of material and the type of dirt or treatment being removed. Green discs are normally used for wax stripping operations.
• Once the said time has passed, remove the residues. Pour a sufficient amount of clean water onto the surface to form an emulsion with the solution on the floor; distribute this evenly with the single-disc machine or brush, and then remove any excess. This operation is best performed with a liquid vacuum cleaner.
• After removing the residues, rinse the surface thoroughly using clean water. If needed repeat the operation, following the steps above.

Opening to floor traffic

After rinsing the surface with water, the floor can be opened for use as soon as it is dry. When applying the treatment again, it is necessary to wait for the surface to be completely dry, all the way through. The amount of time for this will vary according to the type and absorption level of the material.

• Before applying the product to the whole surface, it is advisable to test a small, unexposed area or unused piece to check its suitability for use.
• When applying to recently laid or grouted surfaces, wait
• For the adhesive or grout to cure completely.
• Do not mix with other chemical compounds unless this is expressly indicated, such as in the case of double wax stripping as described above.
• If the finished result is not satisfactory, repeat the process as described above.
