Buyer’s Guide

Getting the right consistency

The first step is to mix the hardener and the filler to get the right consistency from your wood filler. If you are using a tube of wood filler, you should cut it open and pour it into a plastic cup. The next step is to add some water and stir until it becomes a creamy consistency. Once you have added enough water, the mixture should be thick but still smooth. It has the right consistency if you can run your finger over it without trouble.

Choosing siding

Make sure that your siding is in good condition before you start. If it is faded or peeling, the best thing to do is replace it. If you have already chosen your siding for the deck, make sure to find a color match to paint with. Another option, if you cannot get an exact match, is to use a primer from the same manufacturer and then paint over it using another color.

How to sand the wood filler

If there are rough spots on your wood filler, sanding them with fine-grit paper will help smooth them out. Sanding with fine sandpaper can also help in other ways. If there are some small splinters on the surface of the wood, filler sanding will remove them. But if there are some larger splinters, you need to use a wood filler removal tool.

What can you do if you are missing a piece of wood?

Given the amount of work you might have put into installing your deck and making sure that it is structurally sound. The problem with missing wood is that it can become problematic. It is always something to be concerned about.

Imagine a deck with no place to put the lawnmower, a small child who keeps falling off it, and a bird that lands on the deck and breaks its wing. You will likely want to replace the piece of wood as soon as possible to ensure it has never happened again.
