Treating and Fitting Guide

This advice is to be read in conjunction with the treatment advice leaflets that will be inside the wrapper of your door. If by any chance there are no instructions please email the Sales Office at customer-service@tranikdoors.co.uk. Remember to state your order number in any email.

Ensure your doors are stored in a suitable environment, away from any direct heat source and allow good air circulation if being stored for any period of time.

Doors must not be hung or stored in damp or freshly plastered rooms. All new plaster needs at least a six week drying out period before doors should be stored or installed within this environment.

All doors need finishing and should be sealed prior to hanging. Ensure both faces and all four edges are fully treated.

All timber internal doors require protection from the natural moisture content of the surrounding conditions which can vary throughout a property, for example kitchen and bathroom humidity.

Moisture ingress or egress can affect the door within a few hours of being unwrapped but the visual effect of this may not manifest until some time later. As soon as you unwrap your door it is exposed, even if it is inside your garage or home, so treatment must be applied as soon as the door is out of its protective wrapper.

Treatments

Bare timber doors will require light sanding prior to finishing.

Take care to avoid getting finish on the glass of any glazed doors. Secondary protection such as masking tape may be required, including on Paint 'N' Peel doors. If the doors are supplied as Paint 'N' Peel, keep this protective coating in place until finishing has been completed.

If using a varnish

You must treat your door with a minimum of two coats of a good quality solvent based treatment such as Sikkens TSI. A minimum of three coats will be required for steamy areas such as kitchens, bathrooms and shower rooms. Always ensure that the product you wish to use is suitable for engineered doors, and follow the manufacturers guidelines for application.

If using oil

If you wish to use an oil then Osmo Door Oil is the only suitable product to use. Only doors from the Deanta, LPD or XL Joinery brands can be treated with oil.

We do offer very similar designs from more than one brand so do not assume that if the door design you have appears in our website under the named range, that is the door you have purchased. Please email customer-service@tranikdoors.co.uk to confirm the brand you have purchased.

If painting

When applying finishing coats to a door supplied primed you may need to lightly sand the primer, if very smooth, to give a suitable surface for base and top coats. If the door is supplied in bare timber and you wish to paint, a good quality primer must first be used.

Ensure that you use good quality base and top coats, again following the manufactures guidelines and apply with a brush (we do not recommend rollers). Make sure that all products, primer (if required), base coat and top coats are compatible with each other and suitable for engineered / veneered doors. Water based primers and paints are not suitable for use with doors from the Mendes brand.

Prefinished doors

Prefinished doors are supplied with the faces and edges already finished. Do not apply further finishing coats on top of this. As with all doors you will however need to apply adequate finish to any bare areas caused by trimming and hardware fitting.

Whatever your choice of finish, check that the finish manufacturers’ product is suitable for use on veneered / engineered doors. Your guarantee will be void if you use a non-suitable product. If you have any questions over the suitability of a product, please contact us prior to applying the finish to your doors

Fitting

A maximum 2-16mm trimming to each edge which must be removed evenly. **please refer to Technical Information 'Trimming Allowances' for full details**

All doors should be fitted using three ball bearing hinges. In the case of Fire Doors, you must use sufficiently Fire Rated hinges.

Latches and locks should not be fitted adjacent to door mid-rails as this may compromise the joint.

All hardware screw holes should be pre-drilled to prevent splitting of the timber.

To preserve the Fire Rating on any Fire Door you must ensure the door is correctly fitted and appropriate hardware is used in accordance with the Fire Certificate.

Rebated door pairs are supplied with separate instructions for fitting / trimming.

Any areas of the doors which are trimmed during the fitting process, including any cut outs for door furniture, will need to be re-finished in full as soon as the fitting process has been completed.
