Preparation makes or breaks a front door spray job. The good news is that most of the work is done by ColourHaus. There are just a few simple things the homeowner needs to do beforehand. This guide covers both sides: what you should do before the team arrives, and the preparation steps ColourHaus carries out on the day.
- Remove door furniture (knocker, letterbox, numbers, handle) before the team arrives if possible.
- Tell ColourHaus about any chips, cracks, rot or damage during the site visit so it can be factored into preparation.
- ColourHaus handles all filling, sanding, priming, masking and spraying.
- Best conditions for exterior doors are dry days above 10 degrees Celsius with low humidity.
- Door furniture can be refitted 24 hours after spraying once the paint has fully hardened.
What the Homeowner Needs to Do
Your preparation is simple. Remove the door furniture, flag any known damage and make sure there is clear access to the door on the day. That is all. ColourHaus handles everything else. Do not attempt to sand or clean the door yourself before the team arrives, as this can sometimes create problems if the wrong products are used.
Remove door furniture. If you are comfortable doing so, remove the door knocker, letterbox plate, house numbers, handle and any other ironmongery before the team arrives. This speeds up the job on the day. If you would rather leave this to ColourHaus, that is fine too. Our team carries the tools to remove and refit standard furniture.
Clear the area around the door. Move any plant pots, doormats, bikes or furniture away from the entrance. ColourHaus needs clear access and will be laying dust sheets and masking the surrounding area. The more space available, the easier the masking job.
Flag any known damage. If there are chips, cracks, areas of soft wood or suspected rot, mention these during the initial site visit or when confirming the booking. This allows the team to bring the right fillers and repair materials. Small repairs discovered on the day can usually be handled without delay, but significant rot may need to be assessed before spraying can proceed.
Consider access for working at height. Most front doors are accessible from ground level. If your door has a tall fanlight, sidelights above the frame or an unusual configuration that requires working at height, mention this when booking so the team can bring appropriate equipment such as a small platform or ladder.
What ColourHaus Does: The Professional Preparation Process
The preparation ColourHaus carries out is where the difference between a professional finish and a DIY result is made. Every step is important. Skipping or rushing any stage leads to early failure.
Fill and repair. Any chips, dents, cracks or areas of damage are filled with an appropriate filler and sanded flush. This stage takes time on older doors with significant wear but is essential for a smooth final result.
Sand the surface. The entire door surface is sanded to remove any gloss, key the existing coating and create a consistent surface for the primer to grip. The level of sanding required depends on the condition of the existing paint and the door material.
Degrease and clean. The door is wiped down with a degreaser to remove any oil, wax, dirt or residue left from the sanding. This is a critical step because even a small amount of contamination can prevent primer from adhering correctly.
Mask the surrounding area. The frame, doorstep, walls, glass panels and any glazing are all masked carefully. ColourHaus uses professional masking tape and dust sheets to protect every surface that should not receive paint.
Prime. A primer coat suited to the door material is applied. Timber doors get a wood primer. Composite doors get an adhesion primer appropriate for the composite. This stage is not optional. Primer is what makes the topcoat bond and gives the system its longevity.
Spray two coats of topcoat. The colour coat is applied in two full passes with a flash-off period between them. This builds the film thickness needed for good coverage, UV resistance and durability.
Apply lacquer. A clear protective lacquer is applied over the topcoat. This adds UV resistance, protects against minor abrasion and gives the finish its final sheen level (satin, gloss or matt).

Best Weather Conditions for Exterior Doors
Spray painting exterior doors is weather-dependent. The ideal conditions are a dry day with temperatures above 10 degrees Celsius and humidity below 80%. In these conditions, each coat dries and cures at the right pace. In cold or damp conditions, paint takes longer to dry and is more vulnerable to contamination.
ColourHaus plans jobs with weather in mind and will reschedule if conditions on the day are unsuitable for exterior work. In some situations, a temporary canopy can be used to create a dry working environment. The team will always advise you in advance if weather is a concern.
Spring and early summer are the most popular booking times for exterior door spraying in Yorkshire. If you are planning ahead, February and March are good times to book for April and May slots. For more on colour options and how colour affects perceived value, see our article on whether front door colour affects house value and our guide to the best front door colours for Yorkshire stone houses.
Drying and Curing Times
These two things are different. Drying refers to when the paint feels dry to the touch. Curing refers to when it has fully hardened and reached its maximum durability. Touch-dry time is typically two to four hours for the topcoat. Full cure takes five to seven days.
You can gently close the door within a few hours of the final coat. Avoid slamming, pressing hard on the surface or getting it wet for the first 24 hours. Door furniture can be refitted the following day once the paint has hardened sufficiently. For information on how long the finished result will last, see our article on how long front door spraying lasts.
Common Mistakes Homeowners Make
The most common mistake is applying a coat of paint or varnish to the door before calling a professional. This can complicate preparation significantly, especially if the DIY product is incompatible with the professional system that follows. Always call ColourHaus before attempting any surface preparation yourself.
Another common mistake is leaving silicone sealant around the frame or glazing. Silicone prevents paint from bonding to the surfaces around it and should only be applied after spraying, not before. If you have recently resealed the frame, mention this at the site visit.
Finally, do not assume that an old, peeling paint layer will be sprayed over without being addressed. ColourHaus will remove or stabilise any loose material before applying primer. Attempting to spray over peeling paint without stripping it first leads to early failure. Our front door spraying service page covers what is and is not suitable for spraying.
In most cases, no. ColourHaus sprays front doors in place. The door furniture is removed, the surrounding frame, walls and floor are masked carefully, and the door is sprayed on its hinges. This avoids the complexity of rehinging. In some situations, such as when the door needs significant repair work, it may be easier to remove it temporarily.
Most front door spray jobs are completed in a single day. Preparation, priming, two coats of colour and a lacquer finish typically takes five to seven hours. The door can be gently closed by the evening but should not be slammed for the first 24 hours while the paint fully hardens. Door furniture can be refitted the following day.
Small areas of surface rot can often be cut out, filled with a specialist wood repair compound and sanded flush before spraying. This is standard practice for timber front doors. If the rot is structural or affects the door's ability to hang and close properly, the door may need to be replaced before spraying. Our team will assess this during the free site visit.
