In a nutshell: On a construction site, time and material protection are paramount. The HATOCH pH7 Stick is suitable for quick, targeted corrections immediately after priming, while the SPEZIAL 500ml variant is the safer choice for larger areas or unknown substrates – both with a flash point of 65°C, significantly above that of conventional solvents, and without causing material damage to adjacent surfaces.
→ Directly to the suitable product: HATOCH pH7 Stick 50ml or HATOCH SPEZIAL 500ml. For trade businesses, both are also available in boxes of 15 (SPEZIAL) and boxes of 18 (pH7 Stick).
For Painters: Remove Primer Splashes Immediately
Splashes on window frames, tiles, or floor coverings are easiest to remove while they are still fresh. The pH7 Stick fits into any toolbox and is designed for precisely these targeted corrections – with low odor in indoor spaces and a significantly lower fire risk than with open flames or power tools combined with conventional solvents.
For Floor Layers: Remove Residues Before the Next Work Step
Primer residues that are still visible before laying the next covering must be removed without leaving any trace so that the adhesion of the subsequent covering is not impaired. For larger areas or unknown substrate types, the SPEZIAL 500ml variant is more practical, as it covers acrylic/hybrid, silicate, and mineral primers.
Safety on the Construction Site
Both HATOCH products have a flash point of 65°C – significantly above room temperature and well above that of acetone (approx. -20°C) or isopropanol (approx. 12°C). This significantly reduces the fire risk indoors, although normal ventilation rules for cleaning agents are still advisable.

Frequently Asked Questions (FAQ)
Which product is suitable for mobile use on the construction site?
The pH7 Stick (50ml) is compact and ideal for targeted corrections directly on site.
Is it safe to use indoors?
With a flash point of 65°C, both products are significantly less critical than conventional solvents like acetone. Normal ventilation is still recommended.
What to do for larger areas with unknown substrates?
The SPEZIAL 500ml variant is the safer choice here, as it works reliably regardless of the primer type.
