At the end of November 2019 specialists of Shebekinskaya industrialnaya khimiya, LLC (Russia) have done trials of a belt recipe with the use of a hand stucco AA 4646 of Pielcolor production for covering deep defects. The effect of the stucco application was clearly seen. We’ve offered finishing with dull and glossy fixing. The results of the work satisfied the management. Samples for extended trials were ordered. The finished articles will be sent to customers to get a feedback.
