Timber slat decks – decking slippery when wet

Cause

A smooth decking surface – the grooved decking timber is very worn, or non-grooved decking was installed

Repair

  • Replace decking with grooved decking timber

Cause

Grooved decking was installed parallel to the usual path of travel

Repair

  • apply a surface finish to aid slip resistance, and consider lifting and relaying decking at right angles to the path of travel

Cause

Moss has grown on the decking

Repair

  • clean decking to remove dirt and/or moss build-up by water blasting

Cause

Dirt has built-up on the decking

Repair

  • clean decking by washing using a stiff bristle brush with water and a mild detergent, or a solution of 1 part household bleach to 4 parts water; rinse off thoroughly; prime and paint timber decking and sprinkle sand over the top coat of paint before it dries
