**Finishing for External Doors**
PLEASE NOTE:( All Exterior & Interior Doors Should Be Treated Before Fitting The Door.)
For your reference, below is a précis of the widely published Sikkens finishing instructions which is for practical guidance only and not intended to be promoted as being “de jure”. The acclaimed Sikkens range, produced by global chemicals giant Akzo Nobel and widely available from retail stores throughout the UK and ROI, comprises microporous, clear and translucent woodstains and opaque paints, The key advantage of using Sikkens microporous, or “breathable” products, is the finish will not peel, crack, deteriorate or suffer from premature erosion of the film if the decorative finish is correctly maintained.
For optimum protection, each door leaf should undergo an intensive 3 stage finishing process. In respect of Oak and Hardwood timber species, the first stage involves the use of Cetol HLS Plus Base Coat, which is comprehensively applied to all surfaces of the door, to ensure maximum protection. Stage 2 involves completely sealing the end grain of the wood at the top and bottom of the door stiles and at all joints with Sikkens special Kodrin products. Finally, two coats of Top Coat should be applied to all surfaces, which in respect of Oak doors is clear Cetol Filter 7 and in respect of Hardwood doors is Cetol Filter 7 translucent.
The final result, is a fantastic, durable finish, which affords superior protection and enhances the door’s aesthetic appearance.
Depending on location and weather conditions, Oak doors will typically require re-coating every 12 months, whereas it is recommended re-coating Hardwood doors every two to five years, but it is also important to check the finish every six months, and re-coat as necessary, to properly maintain the decorative finish. Please note that the clear finishes offer comparatively less UV protection than Sikkens translucent woodstains or opaque paints, which contain more pigment and therefore afford better protection against UV. Consequently, Oak doors require re-coating more regularly than Hardwood doors, in order to maintain the integrity of the protective finish, so if longer maintenance schedules are preferred, any colour from the Sikkens Filter 7 Translucent range is recommended.
All our range of wooden doors are of an engineered core with an oak or hardwood veneer face.
It is recommended that front doors are always either under a canopy or in a porch to protect against the extremes of weather conditions
The Front Door range of doors are all supplied in their natural state ready to be varnished or painted and the pictures shown are not totally accurate in colour as wood always varies and some styles have been laquered. Oak in its natural state is a honey colour and hardwood is a meranti wood which is a lighter version of mahogany.
Q1. What is the U-Value of a specific external door?
Certified U-Values are available for the majority of XL Joinery Doorsets. These U-Values have been determined by Chiltern Dynamics, an independent UKAS accredited testing laboratory. External doors sold separately are available with indicative U-Values only. These indicative U-Values are based upon information from BRE 443 2006 Edition: Conventions for U-Value Calculations, produced by the Building Research Establishment Limited.
Q2. The label on the door states that I cannot use wax, teak oil or varnish…….why not?
When we manufacture a door it has a controlled moisture content, the above mentioned treatments will not seal the moisture content into the door, therefore allowing moisture ingress or loss to occur causing the door to either swell or shrink. Only a fully paint finish (primer, undercoat & gloss) or high performance wood stain/lacquer should be used.
Q;3 I have broken a piece of glass, can you supply a replacement piece? (applies to all internal doors XL Joinery supply)
These doors are of cassette construction therefore they are built around the glass and there are no loose beads. We do not have replacement glass. If the customer wants to re-glaze, they would need to router the mould off one side of the glazing aperture, remove the broken glass, put new glass in and acquire a new loose beading to re-glaze the door ( probably as cheap to buy a new door).
Q4. The glazing bars on my doors are out of line, not square, what can I do?
The vertical glazing bars can be tapped back into line, these are dry set into the door and could move in transit.
Q5. What is the thickness of glass?
Flat Glass: 4mm approx
Bevelled Glass: 6mm approx
Double Glazed: 14mm approx
Tripled Glazed: 18mm approx
Q6. Can you give out glass sizes?
We do not give out glass sizes for the reason that the measurements could be taken down or given incorrectly.
Q7. What if I receive an obscure glazed door and it has clear patches on the glass?
This effect is usually caused by a substance "filling in" the glass etching and turning it almost transparent, usually caused by silicone. It can be removed with white sprits and vigorous rubbing of the transparent patch. Once the white sprit as been applied, leave to dry and the glass should become obscured again.
