Hello,
gladly.
BUT chromate allergy is not called mason's itch for nothing. In allergy tests at dermatology clinics, chromates with 4–10% positive reactions are among the most common contact allergens in Germany.
The reason is the very high cement content in wood-concrete to achieve usable strength values.
Regards
gladly.
