Are there products in the Siniat range to improve mechanical key on smooth surfaces and prime high or low suction backgrounds?
No, Siniat do not have products for these applications.
The substrate must be clean of all contaminants and dust free. Very low suction backgrounds may require mechanical fixing system. High suction backgrounds will require a 3rd party PVAC bonding agent. Siniat do not recommend specific brands for this.
