  • Stir constantly using electric mixer or hand for around 10-15 minutes. Mix in a thorough fashion to get a paste like, creamy consistency.
  • Prevent formation of lumps during mixing.

Application

  • Apply a single coat of primer before applying putty and dry it overnight. This is recommended by some manufacturers while some do not.
  • The first coat must be applied in a vertical fashion of bottom to top by making use of trowel/ spatula/ putty blade etc.
  • Allow first coat of putty to dry for 6 to 8 hour
  • After it is dry, rub surface gently using emery paper to remove loose particles.
  • Following the first coat, begin application of second coat of putty.
