Instruction for cleaning in between the paint job

Cleaning is elementary for good painting results.

All work must be performed with the appropriate PPE (personal protective equipment) What does PPE include?

Cleaning between the operations

After all sanding work, the object is again cleaned dust-free. This can be done by blowing off and dusting with the dust binding cloth.
Contamination with hand perspiration or grease must be prevented here.
Wearing gloves is recommended (see also PPE – personal protective equipment).

A clean, grease- and the dust-free substrate is elementary for the coating build-up in each layer.
After sanding, filler or primer is also cleaned as described above.

Cleaning before coating

Before applying the paint, it is important here to clean the surface again with silicone remover and, depending on the paint application, with alcohol cleaner. In this step, the silicone remover removes grease and greasy substances. The alcohol or water cleaner removes the last salt residues from the surface.

Then the object is blown off again and wiped with the dusting cloth. Here there is a special feature of the various clothes.

First, there are the so-called „honey clothes“, which are very sticky from the surface.
These clothes should NOT be used for water-based paints. Rubbing with these cloths can cause streaking on the surface, which can show up in the waterborne paint. Thus, the paint finish would be „destroyed“ for some color tones. Likewise, the adhesion of the basecoat to the substrate is interrupted or disturbed by the residues.
The markings caused by the sticky residues can only be removed by repainting.
For this reason, please use the corresponding non-sticky dust-binding cloths for water-based paints.

Some example products* that can be used for cleaning (for most chemical products, preliminary tests on non-visible areas are necessary!)

For the water-based paint, you can get in the trade specially made for this purpose non-stick dust-binding cloths. This should be taken into account when purchasing the materials for the work to be performed.

Now the surface is ready for further paint application.

NOTE:
We also process solvents in the cleaning process. Here you should be aware that a respirator mask should also be worn during this work. For large surfaces, it is absolutely necessary!

Material and tool list

with sample products*

Disposable nitrile gloves

Dusting cloth „honey cloth“ for solvent-based materials or especially for water-based materials – „non-tacky

Silicone remover

EP thinner (slowly volatile thinner. Very good for large bare metal surfaces)

Microfiber cloths

Sanding fleece red (grit approx P240/P360 – before filler application or bare metal. Do not use on the paint!)

Grease and protein solvents (concentrates against stubborn insect residues, grill residues, etc.) – prior testing required!)

Insect remover (spray, soak, rinse. Of course it’s not that simple 😉 )

PPE

Work gloves

Disposable gloves

For long hair and working on rotating and cutting tools, tying the hair together is a must!

Safety goggles

Coarse dust mask for grinding and sawing work

Respirator mask for painting and cleaning A2P3
