Place the pavers upside down on a clean surface. Smooth around the edges with 60-grit metal abrasive paper. Place the pavers on timber offcuts to elevate them off the workbench, then smooth around the sides and tops with 120-grit metal abrasive paper.
Spray tile cleaner over the tops and sides, wipe with a cloth, then spray with water and remove residue with a clean cloth. Leave to dry.
Apply sealer with a mini roller, leaving it to soak in for a few minutes, then apply a second coat before it dries. Repeat for a third coat, keeping the surfaces wet. Wipe around the base to remove drips, then leave to dry thoroughly.
Referring to photo 4 above, mark 450mm from the bottom left corner of the plywood. Use a protractor to mark 60º at the corner and your mark, then use the square to draw a triangle of equal sides. Leaving a gap of 3mm between each, draw a 370mm triangle along the top edge, then a 300mm triangle. (Setting them out like this minimises the number of cuts.) Use a handsaw to cut triangles, following the order shown, working off the edge of a stable workbench.
Tip: Cut along the outside of the line as the 3mm gap allows for the width of the saw blade.
On the triangles, position leg plates 50mm from the corners, marking the holes and along the tips. Remove the corners with a handsaw, then drill the screw holes with a 2mm bit and the centre holes using a 6mm bit. Secure the leg plates with the supplied screws. Attach 150mm legs to the 300mm base, 230mm legs to the 370mm base, and 400mm legs to the 450mm base. Sand the legs with 180-grit paper and add self-adhesive glides to the bottom of each leg.
Use a measuring tape to centre the bases on the corresponding pavers and mark around them. Apply adhesive, re-position the bases, clamp and leave to dry.
Handy tip: A standard 18mm-thick plywood sheet is 1200mm x 600mm, but since the table bases only require half, have it cut widthways in store so it's easier to manage. The 18mm thickness allows for the length of the leg bolts and avoids having to drill into the concrete.
