Fitting Wooden Worktops

Fitting wooden worktops

The guide explains and sets out the requirements and procedures for fitting wooden kitchen worktops.

Wooden kitchen worktops are made from solid hardwood staves with a moisture content of 10 – 11% at time of manufacture. They are designed to be used in normally heated, furnished domestic interiors.

Hardwood is a natural material and is affected by changes in temperature and humidity. It expands and contracts naturally across the grain. Observance of the correct installation procedure carried out in properly conditioned interiors will prevent any problems from occurring.

The manufacturers will not be liable for solid wooden worktop failure that arises from poor fitting, the wrong fittings and materials being used, inappropriate or adverse site conditions or any other failure to follow the wooden kitchen worktops fitting procedures and requirements set out in this guide and the care and maintenance routines.

The Installation kits are required for the proper fitting of wooden worktop, while the Care Kit will help you to maintain wooden worktops for years to come.

The Installation and Care Kits need to be specified at the time of order. They can be found in the on-line store.

The Fitting kits include:

– slotted steel stretcher brackets and screws to fix down the tops
– low modulus (flexible) clear silicone sealer for sealing joints, to sinks, to walls and to adjacent furniture

– worktops bolts and biscuit joints to align and clamp up joints between pieces of worktops

Wooden worktops fitting should be done as soon as possible after delivery.

If storage is necessary, the tops must be kept in a weather tight environment, at a temperature and humidity the same as the room (in normal use) where they are to be fitted, no wet trades being carried out, no wet or drying building work.

Store the tops flat and level, supported on battens at 500 – 600mm centres in their original wrapping and completely away from any sources of heat or moisture.

Never store them on edge or on end.

Never store them where any building works are going on.
