How to glue objects using an F-clamp


	Shop for clamps


		A common use for an F-clamp is to hold a number of workpieces in place, without any movement, while the glue which will bond them together sets.

		A tip to remember before you begin is that the moisture in the glue can cause the metal bar of the F-clamp to leave a dark stain on material, especially on wood. To avoid this, lay a sheet of wax paper over the bar of the clamp.

		Step 1 – Choose glue Before you begin, choose the appropriate glue for your project. There are many different types available, which are designed for different purposes and materials, so be sure to check the label before applying.

		Step 2 – Apply glue Carefully apply the glue to the parts which you wish to stick together. A flux brush (a brush designed to apply adhesives evenly) may come in handy here. Use it to spread the glue across the surface.

		Step 3 – Position parts Once the glue has been applied, place the parts together.

		Step 4 – Place clamp Place the clamp over the attached parts and close the jaws. The clamp should only be closed tight enough to firmly, but gently, hold the glued objects together.

		Excessive force is not needed, as too much clamping pressure will lead to an uneven glue line due to the glue leaking out of the joint. This could result in the parts coming apart in the long term.

		Step 5 – Spread pressure The clamping pressure should be spread evenly, meaning on large workpieces more than one clamp may be needed. Spread the additional clamps out along the workpiece to distribute the pressure.

		Step 6 – Leave to set Leave the clamps holding the parts together until the glue has set.

		Step 7 – Remove clamp Once the glue has set the clamps can be removed from the workpiece.
