Painting decks

 

Decks consist of many pieces of wood, the ends of which can soak up moisture.

Decks consist of many pieces of wood, the ends of which can soak up moisture. Properly cover these ends and any parts lying near the ground to keep the wood from soaking up too much moisture.

Don’t paint in the sun, if there is dew, if it is freezing, rainy or if the moisture content of the wood is greater than 12%. The best temperature for painting is between 15 °C and 25 °C (60 °F and 77 °F).

You should prime certain types of knotty wood with a coat of Polyprep 205-112 on the knots before applying an opaque coating. This product prevents bleeding of knots and sap veins of soft resinous woods like pine, spruce and fir. Check by applying 2 coats of coating to an out-of-the-way section of the wood.

Painting decks:

  1. Paint the underside of the boards before construction.
  2. Paint the horizontal sections.
  3. Paint the ends.
  4. Paint the sides and tops of the boards in 2- or 3-foot sections, starting with any cracks and knots. Let paint soak into cracks and knots to keep out any water that could cause mildew.
  5. Smooth over surface from the unpainted to painted portions.
