How to Seal Birdhouses


Locating paints that are suitable for use on bird feeders and birdhouses is an essential step in the process of ensuring that the building will not be harmful to the feathered companions you keep. Before beginning any project involving the construction of a new birdhouse or the painting of an existing one, it is important to familiarise yourself with the proper procedures for selecting non-toxic paints, stains, and other supplies.

Safe Paint for Birdhouses

Brightly coloured birdhouses may have an appealing appearance, but Happy Gardens warns that they may also draw the attention of potential predators, such as squirrels and birds of a bigger size. It is best to go with neutral colours since they give some concealment for the home as well as any flying visitors who may come to visit. Birds may be placed in danger by their attraction to bright colours such as blue and red, despite the fact that these hues may entice them. Happy Gardens recommends instead selecting a colour closer to olive green, brown, white, grey, or taupe.

When you go to the store to get paint, avoid picking up any versions that include heavy metals such as zinc or lead. Before you re-paint an already painted birdhouse, you might consider stripping it first if you are unsure of the kind of paint that is already on the surface. You should look for water-soluble exterior paints that are based on latex. Acrylic paints are chemically based; thus, you should avoid using them around the birds for their own protection.

Painting the birdhouse in the winter will ensure that it is prepared for usage when nesting season arrives in the spring. Apply two coats of paint to the outside of the birdhouse, being sure to wait for the first coat to thoroughly dry before moving on to the next. Paint should never be used on the inside of the birdhouse since it might be harmful to the baby chicks that are housed there.

Weatherproofing a Birdhouse

Birdhouses should be made of natural wood for the greatest results. Plastic, metal, and other types of materials do not give the same level of insulation that wood does, which is why this is the case, according to the Alaska Department of Fish and Game. It makes me think of plywood with a 3/4-inch thickness, rough-cut slabs, or tree parts. Check to see that the wood has never been treated with creosote, since this substance may be harmful to young birds and their eggs. In order to prevent rust, the nails need to be galvanised.

The yellow and white pine, spruce, and cedar trees are examples of some of the most rot-resistant types of wood. The birdhouse does not need any painting or staining, although doing so will help protect it from the elements and ensure that it will endure for more than just one season. You could want to experiment with a stain that is water-based and is designed specifically for the kind of wood that the house is built of.

It is suggested that you choose natural wood that has not been stained or painted since bird advocacy organisations like NestWatch assert that there are no conclusive studies that prove if there are wood dyes and paints that are 100 percent safe for birds. It is possible to increase the water resistance of a birdhouse by glueing and then firmly nailing together all of the seams. Be aware as well that the durability of angled birdhouse roofs is superior to that of flat roofs. You may also bring the floor down by a quarter of an inch, which will protect it from damage caused by dampness.

Birdhouse Tung Oil

You may try out a different sort of finish on a birdhouse if you want to shield it from the outdoors while also improving its resistance to the weather and its longevity. The use of tung oil or linseed oil is recommended by Gizmo Plans since either one will harden and cure the wood. Tung oil would need to be applied in about five coats, but it creates a more effective barrier against moisture than linseed does.

You are going to require sandpaper, wood filler, waterproofing tape, and tung oil in order to complete the finishing of the birdhouse with tung oil. Sand down the outside until it is nice and smooth, then use the wood filler to fill in any depressions or tiny holes that you may have found. The next step is to seal off any sections that you do not want completed using tape. Apply five applications of the tung oil, being sure to give each one enough time to dry in between the previous one. Even while it may seem like a time-consuming task, if the birdhouse is not abnormally huge, finishing this project shouldn’t take you very long at all.
