For Neoprene:
If Neoprene rubber has been Talced then this should be removed by washing with detergent or wiping with solvent soaked rag. Liquid Rubber can be applied directly to Neoprene. Some swelling of the Neoprene should be expected but this will recover over time. The distortion resulting from the swelling will be greater if Neoprene is thin and not adhered to a rigid substrate.
For Polyurethane:
A light sanding of the surface is recommended for better adhesion. No swelling will occur.

UNACCEPTABLE APPLICATIONS
Do Not use Liquid Roof or Liquid Rubber on the following substrates: For the below applications you can use the asphalt based system located here Asphalt Based Repairs

Built up asphalt roofs
Asphalt shingles
Modified asphalt roll roofing
Trafficked areas such as decks or patios
