The Worktop Express Nutshell Guide to Joining Earthstone Worktops
Earthstone worktops are an attractive, low-cost alternative to natural stone surfaces. Correctly joining Earthstone worktops gives the appearance of seamless, custom-built work surfaces. In this guide, we will cover exactly how to create perfect masons mitre and butt joints for Earthstone worktops.
Mason’s Mitre Joint
When utilising the mason’s mitre corner joint method for Earthstone worktops, it is recommended that biscuits are used.
Step 1.Align the jig and the worktop before clamping in position. For a left hand 90 degree joint, the female joint router needs to be face up, whereas the male joint router should be face down. The opposite is true for a right hand 90 degree joint – the female joint router needs to be face down, whereas the male joint router should be face up. When routing an Earthstone worktop, it is important to avoid making a single cut – instead, make three 12mm deep cuts in succession.
Step 2.Cut out three jointing bolt recess for a 650mm worktop or four for a 900mm worktop. Ensure that you offset the straight edge guide to suit the router you are using in order to achieve a clean and professional cut.
Step 3.Next, you need to make the pockets for the biscuits. No.20 biscuits are recommended, so, using a biscuit jointing machine, you should cut 20mm deep pockets to accommodate them. Make the cuts between each connector bolt recess.
Step 4.Using industrial denatured alcohol, clean the surfaces of the Earthstone worktop, taking special care to avoid the chipboard. Wait until the surface is dry then assemble immediately.
Step 5.Apply a small amount of Earthstone colour match adhesive to the biscuits and insert them into the pockets. Apply a bead of adhesive along the top edge of the cut and a second 5mm up from the bottom, before bringing the two worksurfaces together. Ensure that the faces align for an inconspicuous and stable join.
Step 6.Place the connection bolts into the jointing bolt recess and tighten them using a 10mm spanner, ensuring that you do not over tighten them. Wait 40 minutes for the adhesive to harden before removing any excess using industrial denatured alcohol.
Butt joints are used to join two straight lengths of Earthstone worktops. The method is similar to that of mason’s mitre joint, the only difference is the first step.
Step 1.To create an invisible join, both work surfaces have to be exactly parallel. To do this each worktop should be milled at right angles and then straight. The next steps are identical to the mason’s mitre joint so please follow steps 2 – 6 above.
