Timber, which has been exposed to the elements for more than four weeks, should be sanded back to a fresh, new surface. A grey or weathered surface makes an unsound base and will encourage peeling and flaking. Sand the surface to remove all greyed timber. Punch any nails well below the surface, spot prime and fill the nail holes with an exterior timber filler, such as Selleys Plasti-Bond. Sand smooth and apply Dulux 1 Step Acrylic Primer Sealer Undercoat to maximise paint durability.
Dear Sir/Madam, I would like to purchase 4L White paint for painting the exteriors. 1. The surface is metal (gate) and there are some rusts on it. I need to clean up the rusts and then paint it. a. What paint do you recommend? b. Can I apply the paint directly on the metal gate after the purchase or do I need to mix with other solutions? c. What is your quote? 2. The surface is exterior wall. Again, I need to clean up the moulds and then paint it. a. What paint do you recommend? b. Can I apply the paint directly on the exterior wall after the purchase or do I need to mix with other solutions? c. What is your quote? Please advise, Regards Malai,
