Top Tip

Always work in shaded areas during the hottest part of the day. If you are applying in hot, windy or on porous surfaces, thin the first coat by up to 10% with water.

Step 4: Let's Paint

After all that preparation, it's time to get paint on the walls. Once again we've pulled together some tips to make the job a whole lot easier.

Painting 1

1. Stir paint well before and during use with a broad paddle.

2. Use quality tape to mask off windows or trim.

Cover grass and shrubbery with drop cloths.

3. Paint only one wall at a time.

Painting 2

Brush a border around fascia, doors & windows with a 75-100mm synthetic brush, this is called 'cutting in'.

If painting with white & white tone colours on tannin or resin rich timber, apply an initial coat of Pascol Sunscreen as a sealer. Allow resin rich hardwoods to weather for 4 - 6 weeks before applying this initial coat.

4. Start painting at the highest point of the house we recommend following this sequence:

Painting 3

1.Eaves  2.Gutters  3.Fascias  4.Walls  5.Doors & Trim

When brushing large surfaces, (e.g. weatherboards), always work along the length to a natural break to minimise lap marks. Keep a wet edge (not letting the paint dry) by brushing back into immediately applied areas. Large flat surfaces may be cut in by brush & then rolled. Once the entire area has been painted with the first coat, the area is ready for a second coat by repeating this process.

5. Continue painting across the house.

Brush towards the unpainted area and then back into the just painted surface to prevent lap marks. Picture framing occurs when a wet finish coat is applied on to areas that already have dry paint.

Don’t 'cut in' the entire house before rolling out paint.

Work in sections in order to maintain a wet edge by painting into the wet paint so the paint blends with what has already been applied.

Roll over the 'cut in' area as much as possible without touching adjacent areas that are a different colour.

6. Next apply paint to trim, window, and frames.

Tips: Painting Exterior Trim

Water based vs Oil based Trim: Today's water based enamels are as tough and durable as traditional oil based enamels in most painting situations and have better exterior durability. Using a water based enamel offers the added benefit of low odour, non-yellowing and fast drying compared to traditional oil based enamels and they are better for the environment. Traditional Trim oil based enamels tend to chalk, crack and peel when exposed to exterior conditions resulting in loss of gloss and film failure. Most satin enamels are not exterior durable. Pascol Trim Water Based Enamels are exterior durable in both a Gloss and Satin finish.

Paint the Trim

Use a 25 - 65mm brush for doors, window frames and woodwork.

Great tips for applying enamels:

  1. Spread the paint quickly to an even film over a small section, laying off lightly into freshly painted sections.
  2. Avoid applying excessively thick coats as running or sagging may occur. Rebrush any runs or sags immediately. Don’t wait until the paint has started to dry.
  3. Splashes should be removed immediately with a dampened cloth.
  4. For best results to achieve a smoother finish, lightly sand after undercoating and between finishing coats with 240 or finer abrasive paper & remove dust.
  5. Coat window frames sparingly. To avoid sticking, move windows within 30 minutes and again in the first 24 hours.

To achieve the best results on your trims, preparation is key for the perfect finish
