Tarmac Whitewall Plaster

  1. Meshed Membrane Finish: Tarmac Whitewall Plaster is the recommended finish for Newton Meshed Membranes, delivering a smooth, hard, and durable white finish. Proven since the 1980s, it excels when applied over Newton 803 Newtonite and Newton 805 Newlath.
  2. Easy Application: Supplied as a powder, Tarmac Whitewall is easy to store and use. With coverage of 13-15 kg per m² in two coats (each 6mm thick), it provides a reliable and attractive white finish.
  3. Tailored to Meshed Membranes: While typically a single coat for most substrates, Tarmac Whitewall Plaster requires a two-coat application for Newton meshed membranes. It’s essential for a subsequent smooth finish coat, ensuring the best results before decoration. Refer to the installation instructions for the specific membrane for detailed application guidance.
