Putting on the sealant
When the sealer is still wet, you should brush it to remove any remaining residue. You can apply the sealer by rolling it on or spraying it on but always remember to back brush after each application. Apply the sealer with a roller and immediately brush it back into place after it has been rolled on.

The surface tension of the composite deck will be increased if the sealer is brushed back into the wood grain.

Using more sealant than the composite can absorb will result in excess product being wiped away. Excess residual sealant can cause shiny moving spots on the deck surface if there is too much of it.
