A number of edging profiles can be supplied, either factory fitted to Simmons’ epoxy resin worktops or in loose lengths for fitment to other materials. Loose edgings can be supplied pre-cut and mitred at an additional cost.
Epoxy resin grout/adhesive is recommended for fitting all edgings.

As with all worktops a reasonable standard of laboratory housekeeping will help to keep the worktops in good condition. All spillages should be cleaned up as soon as possible. Staining agents and aggressive chemicals should not be allowed to sit in contact with the tops for a prolonged period of time.
Areas of chemical attack or staining can be removed with a polishing compound or very fine abrasive paper, but it should be stressed that this will alter the finish of the surface. Performance will not be affected.
The use of a wax furniture polish will help to retain the gloss finish.
Components should not be exposed to dry-ice or liquid nitrogen and heat insulation pads should be placed between a top and a steambath or hotplate to prevent thermal stress.
List of Tools and Equipment required:-
All edging and upstand should initially be dry fitted to check for size and fit.
Minor adjustments can be made using 80 grit sandpaper.
The underside of the edging or upstand and the area onto which it is to be fitted must be rubbed down with sandpaper and then with cellulose thinners.
Both components have a coating of release from the casting procedure which will prevent anything bonding to it unless this coating is removed.
A mix of grout should then be prepared as described above. When completely mixed this should be applied in a thin layer to the underside of the edging/ upstand. The edging should then be placed in position and securely clamped down (using blocks to protect the surface of the edging). This will squeeze out any excess grout which should be removed with a sharp flat chisel when it becomes rubbery. After approximately 10 – 15 minutes when the grout has fully hardened the clamps may be removed.
It is important that a radius fillet of grout is applied to the joint between edging and the worktop so as to ensure that there is an easily cleanable and fully sealed joint. A fresh mix of grout should be prepared as described above.
When completely mixed this should be applied along the joint using the wooden sticks provided. A final run around with the radius end of the stick will give a tidy finish. When the excess grout becomes rubbery it should be very carefully removed using a sharp flat chisel. Approximately 1 hour after this the joint can be wiped down with cellulose thinners.
This radius fillet is not required with flat sheet upstands which meet the top at a 90° angle.
Grout is supplied as a pack of two components :- resin and hardener. Once mixed the grout has a workable life of approximately 5 minutes. It is therefore essential that only a manageable amount of grout is mixed at one time, and that all preparatory work is done before mixing.
The resin and hardener should be measured out at the ratio stated on the containers onto a mixing board. When ready for use this should be thoroughly mixed using the wooden sticks provided until the two components are homogeneous.
Please note that a minimum room temperature of 5°C is required to initiate the cure cycle for the grout. The useable life of the grout will vary with the ambient temperature. The warmer the room the quicker the reaction.
It is recommended that Latex gloves are worn whilst using epoxy resin grout components and cellulose thinners.
