introduction

The frequency of painting or coating wood decking is not the same for all locations.

Malaysia's tropical weather with heavy rain and scorching sun accelerates the wear and tear of decking surfaces . Without proper maintenance, decking can easily crack, become moldy or rot.

Functions of Sealant & Paint for Decking

Protection from weather & moisture

Sealants and paints work to:

• Prevents air absorption which causes reputation

• Protects wood from UV rays that cause color fading

• Adds a layer of protection against fungi and insects

• Highlighting the natural beauty of wood grain

Factors Determining Frequency of Painting/Sealing

Not all decking needs to be treated equally often.

Some of the main factors are:

• Type of wood : Hardwood (merbau, balau) lasts longer than pine or softwood.

• Sealant/paint product type : High quality product lasts up to 2 years.

• Level of weather exposure : Exposed outdoor decking needs to be serviced more frequently than protected decking.

• Frequency of use : The more often you use it, the faster it wears out.

Recommended Frequency In Malaysia

General recommendations for tropical climates

• Once a year : Most recommended for decking that is fully exposed to rain and sun.

• Every 18–24 months : For partially covered decking and use premium products.

Tips:

• Do the sealing before the rainy season.

• Use special paint or sealant for outdoor wood (outdoor wood finish).
