Fill Large Gaps in Wood Using Super Glue
Fill Large Gaps in Wood using Super Glue
Cyanoacrylate glue, commonly referred to as super glue is an adhesive that has numerous applications. Due to the fact that it sets in quickly and does not require clamping it is widely used in the woodturning industry. In particular, the glue is used to fill in gaps and cracks in wood. Available in several viscosities, this glue is preferred to epoxy and conventional gap filling wood glue. For purposes such as filling gaps and cracks, thick super glue is the best option because thin super glue tends to flow through the crack without bonding it. This is especially in cases where the crack has a considerably broad width.
It is important to note that thick super glue takes more time to cure than thin glue. Nonetheless, it is capable of bonding two sides of wood better than thin glue. This is the main reason why thick super glue is used for filling gaps. When using this type of glue, it is important to take in to account the health risks posed. While it is not as dangerous as using a hacksaw, a small drop of the liquid squirting into the eye can cause a lot of pain and discomfort. Additionally, the glue produces an unpleasant and acidic odor that can be harmful to some people.
For safety precautions make sure to use a mask and glasses when working with this type of glue. When applied to a gap or a crack on wood the glue will start curing. Due to its low viscosity, thick glue will cure slowly which gives time for adjustments. Due to the slow curing of this type of glue, it is advisable not to use it on cracks wider than 0.25 mm. Pressing the two sides of the wood together will make the glue cure almost instantly.
To make the glue easy to work with it is wise to combine it with another material when filling wider gaps. Some woodturners use sawdust and combining sawdust with the glue is possible to create a thick filler that hardens quickly. The resultant filler material can be drilled and also sand papered. Apart from saw dust baking soda is also used to create a gap filler material using super glue. While there is a host of liquid accelerator substances that have the same effect, baking soda and saw dust are safer to use. Thus, many prefer either of the two to commercial accelerators. Most commercial accelerators are alcohol based and can be found in most woodworking stores.
For filling large gaps, a mixture of super glue and baking soda is the best option. The filler material that is created is ideal for filling large gaps. Also, the type of super glue to use to create the filler is the liquid type and not the gel type. Below is a step by step process of creating a filler material for filling gaps using super glue. This process can be used in woodworking and woodturning projects.
How to Create a Filler Material Using Super Glue
Step one: Gather all materials necessary. The materials needed to create a filler for filling large gaps include thick super glue, baking soda, a small spoon, sanding paper, and tape.
Step two: Put baking soda into the crack or gap that is to be filled. This is followed up by the addition of super glue into the hole or gap. Depending on the size of the hole or gap, it is important to add baking soda and then add super glue until the crack is filled. The baking soda helps quicken the curing process and create a sand like substance.
Step one: As stated above saw dust can also be used in the same manner as baking soda. In the case of saw dust, all that is needed is the super glue and the saw dust. Once these two materials are present, the saw dust should be applied to the hole or gap that needs fixing.
Step two: After the saw dust has been poured into the hole or gap, super glue is then added to it to create a hardened substance. This method is great for filling large gaps or cracks in wood.
Super glue can also be used to fill gaps and crevasses on wooden surfaces. Where there has been an accidental damage to a wooden surface thick super glue can be used to fill the gap. As with other gaps baking soda or saw dust will come in handy when creating a filler material. To fill a crack on a wooden surface a little super glue is applied first. Then baking soda is added second. The mixture is allowed to sit for a few minutes for it to harden. After the area has hardened a sand paper or any other kind of sander is used to flatted the area. This is important to create a flat smooth surface.
In woodworking, a combination of sawdust and super glue is used to fill nail holes that are to be left unpainted. To fill such holes, super glue is first mixed with saw dust from the wood where the holes appear. The thick mixture that is created is then applied on to the holes using a putty knife. The mixture dries quickly thus it is important to push the mixture through the holes quickly.
Super glue is an instant adhesive that revolutionized the woodworking and woodturning industries. This strong adhesive has since been used with other woodturning supplies to create beautiful wooden finishes, turquoise inlay, metal powder inlay, and mother of pearl inlay. However, it has excelled in being used as a gap filler, bonding adhesive, and repair glue. The fact that it cures quickly makes it an ideal adhesive for this task. Additionally, with accelerator substances such as baking soda and saw dust, this adhesive is able to create filler materials that can be sanded and drilled. It is for this reason that it is used to fill large gaps. The result is always a smooth surface that does not look like it had cracks or holes.
