Primer and deep primer – are they the same thing?
Short answer: Yes, essentially. Both terms describe a pre-coat applied before the main paint coat to improve adhesion and strengthen the substrate. In professional trades, the term Tiefengrund (deep primer) is typically used, while DIYers more often use the term Grundierung (primer).
The difference lies more in the composition: there are acrylic primers, silicate primers, and hybrid primers – all of which fall under the umbrella term "Tiefengrund" (deep primer).
The real problem: primer in the wrong place
Who hasn't experienced it: a splatter of primer lands on a plastic window frame, a glass pane, or tiles. While fresh, it can be wiped off – but once dried, it becomes a real challenge.
Typical mistakes when removing it:
- Scraping with blades: Risks scratches on glass and plastic
- Solvent-based cleaners: Can dissolve or dull plastic frames
- Household remedies like vinegar or spirits: Have little effect on mineral primers
Why conventional cleaners fail
Acrylic, silicate, and hybrid primers have different chemical structures. A normal all-purpose cleaner is not designed to break down these polymer structures. The result: you rub and scrape – and the primer remains.
Silicate deep primer, in particular, is considered particularly stubborn because it cures mineralogically and embeds itself deeply into surface pores.
The right solution: specialized remover instead of household remedies
The HATOCH® Deep Primer Remover SPECIAL was specifically developed for this problem. The utility-model-protected formula (DPMA DE 20 2021 105 495) penetrates even the toughest polymer structures – whether acrylic, silicate, or hybrid primer.
