Optimal Processing Conditions

Optimal processing conditions are between 15 - 25°C and a relative humidity of 30 - 60%.
High temperatures and low humidity shorten the drying time, while low temperatures and high humidity extend the drying time.
Do not process in direct sunlight to avoid too rapid drying of the paint and the formation of bubbles on the surface.
Do not paint when it is windy to prevent dust from settling on the surface before it dries.

Which tool is the right one?

For water-based paints, acrylic varnishes: flock roller or a short-pile lambskin roller, brush with synthetic or artificial fiber bristles
For solvent-based paints and varnishes: short-pile rollers (for example Vestan rollers) that do not trap air, natural bristle also called China bristle
For floor coating: lint-free paint roller
For facades: masonry brush, also called painter’s brush, or a simple paint roller
For PU varnish: paint rollers made of mohair, pile, velour, smooth felt, Royal, Rolloplan. Foam rollers are unsuitable!

How do you clean tools?

It depends on the materials you have worked with:

If it was a water-based product – you can manage with water
If it was solvent-based – use a universal thinner

Cleaning tools contaminated with epoxy resins is a bit more complicated. You should always weigh up cost vs. benefit:

Cleaning brushes, rollers, mixing cups, etc., is not worth it. The cost of cleaning agents is already significantly higher than using new tools. For simple tools, it is better to let them harden and use new ones.
When cleaning expensive tools, you should keep in mind that work equipment must never be cleaned with solvents or thinners. Even the smallest traces of solvents on the tools can prevent the epoxy resin from curing in your next project. In this case, all your work would be in vain.

Why is the paint or oil not drying?

Possible reasons:

At temperatures below +15°C / above +25°C and humidity over 70%, the drying time is extended
A thick layer of paint takes longer to dry
Products such as cleaners or degreasers can slow down the drying time
Both components of the epoxy paint are poorly mixed or incorrectly distributed

The surface is still sticky after a few days of drying. What can I do?

Possible reasons:
If the paint was applied thickly or the excess oil was not removed from the surface, the wood may remain sticky.

What to do:
You can use a soda lye with warm water or sand the surface mechanically and then reapply the paint or oil.
