Solid Timber Interior Door

Our factory-engineered solid timber interior door adopts wood-based structural assemblies for a robust, long-lasting build. In line with project specifications, solid wood can be integrated with engineered wood materials including LVL and MDF to enhance dimensional stability and streamline production efficiency.

Within lacquered wooden door ranges, our solid timber interior doors feature a high-temperature baking varnish process. Multiple layers of specialized coating are sprayed onto door slabs and thermally cured, delivering a smooth, uniform finish with waterproof, moisture-proof, scratch-resistant and anti-cracking properties for a premium finish. This is a widely adopted finishing method for premium interior wooden doors. In contrast, paint-free doors skip onsite painting: they use HDF as the base substrate, bonded with PVC or other decorative overlay layers. Both options carry distinct benefits. Lacquered doors provide superior aesthetics, refined texture and extended service life, ideal for residential projects focusing on quality and long-term performance. Paint-free doors offer cost advantages and shorter lead times, perfectly suited for housing developments and bulk orders. You may select the appropriate solution according to your project requirements.

Why Combine Solid Timber with Engineered Wood?

• Improves structural consistency
• Allows accurate dimensional production
• Supports large-scale manufacturing
• Provides flexibility in surface design
• Allows different core configurations
• Helps balance performance and project cost

Different projects have different requirements for appearance, stability, weight and budget. We can configure the door construction according to the intended application.

Solid Wood Components

Suitable for projects where a more substantial timber construction and natural wood character are important.

LVL Structural Components

Provide consistent structural dimensions and are suitable for repeatable project manufacturing.

MDF Door Face

Creates a smooth and stable surface for painted, lacquered or decorative finishes.

Solid Wood Core

Provides a heavier and more substantial door construction.

Honeycomb Core

A lighter option when weight and cost efficiency are important.

Custom Construction

The combination of MDF / LVL / Solid Wood / Core Filling can be adjusted according to the project specification.

The painting process for solid timber interior door is as follows:

1. Clean and remove oil stains, then use water-based putty to fill nail holes, cracks, depressions, pits, and other defects. Generally, wood-colored water-based putty is used, and the principle is that the color must be the same as the natural color of the wood.
2. Sand the door with 150 grit sandpaper to make it smooth.
3. Polish the door panel with 180 grit sandpaper until it is smooth and flat.
4. The workers apply the stain. For wood with large pores, you can first apply a layer of stain. For wood with small pores, such as pine, staining is not necessary. Staining is only used for special process requirements.
5. we apply the first coat of clear varnish. Generally, when applying clear varnish, you should apply two coats. The first coat should be thinner and the varnish should be slightly thinner. Allow it to dry completely for more than 12 hours. Sand it smooth with slightly fine sandpaper before applying the second coat. After the second coat is completely dry, sand it smooth with polishing sandpaper.
6. Workers apply putty to fill in any gaps. This putty repair mainly corrects any defects missed in the previous step.
7. Sand with 180-grit dry sandpaper, then with 240-grit and 320-grit sandpaper, and finally with 600-grit or elastic cloth for polishing.

After this, apply the second coat.

A quality painted timber door depends not only on the coating itself, but also on surface preparation and sanding between coating stages.

The landscape painting in the background, the blue and white porcelain vase, the bonsai, the Chinese-style long table, and the wooden lattice partition on the left are all typical Chinese symbols, conveying an elegant and understated oriental charm. The solid timber interior door stands calmly and gently in the elegant space of the new Chinese style. Every time the door is opened, it adds a touch of just the right amount of refinement.

The wall lamps, minimalist black door locks, and clean-lined wooden door design echo the warm wood finish throughout the house. Opening the door reveals a tranquil and elegant oriental ambiance, while closing it shuts out the outside world's noise, creating a space of relaxation and peace just for you.

Solid timber doors are sensitive to environmental conditions, so material selection, moisture control, construction and finishing should be considered together.

• Target Country / Climate
• Timber Moisture Requirements
• Door Thickness
• Core Construction
• Frame Construction
• Surface Finish
• Installation Environment
