Table revarnishing

For UK homeowners, this process is an environmentally friendly alternative to buying new. A high-quality finish not only enhances the aesthetic of your dining or living space but also significantly increases the longevity of the timber, protecting it from moisture, heat, and UV damage.

What Does the Work Involve?

• Initial Assessment: The restorer inspects the wood species, identifies the existing finish (wax, oil, or lacquer), and checks for structural issues like loose joints or lifting veneers.
• Surface Preparation: Surrounding areas are protected with heavy-duty dust sheets. The old finish is removed using specialist chemical strippers or controlled mechanical sanding with dust extraction.
• Repairs and Staining: Dents are steamed out or filled, scratches are sanded, and joints are reinforced. If a colour change is requested, a wood stain is applied evenly to the bare timber.
• Coating Application: A primer or sealer is applied, followed by 2–4 coats of high-quality varnish (polyurethane, acrylic, or traditional resin), with light "denibbing" (sanding) between each layer.
• Finishing and Curing: The final coat is left to level and dry in a dust-free environment. The tradesperson will then provide advice on curing times before the table can be used for heavy items.

Typical Costs

The cost of revarnishing varies based on the table's size, the complexity of its design (e.g., carved legs), and the level of repair required. Prices generally include all materials, professional-grade abrasives, and waste disposal.

Note: Premium finishes like French Polishing or high-gloss "piano" finishes will sit at the top end of these estimates due to the intensive labour involved. Always clarify if VAT is included in your quote.

How Long Does It Take?

• Small Projects (Coffee Tables): 1 day. Sanding and initial coats can often be completed in a single visit, though curing takes longer.
• Standard Dining Tables: 2–3 days. This allows for thorough stripping, drying time between multiple coats, and final buffing.
• Complex Restorations: 4–7 days. If the table requires significant structural repair or veneer work, it may need to be taken to a workshop.
• Curing Time: While the table may be "touch dry" in 4 hours, most modern varnishes require 7–14 days to fully harden (cure) before you should place heavy or hot objects on them.

DIY or Professional?

While a basic sanding and "refresh" is achievable for a confident DIYer on inexpensive pine furniture, professional restoration is highly recommended for valuable hardwoods or antiques. Professionals use industrial-grade dust extraction, preventing fine particles from coating your home, and have the expertise to handle chemical strippers safely.

Professional furniture restorers have access to AC (Acid Catalyst) lacquers and high-build varnishes that are far more durable than the "off-the-shelf" products found in local DIY sheds.

Attempting to sand a veneered table without experience often results in "sanding through" the thin layer of decorative wood, which can be an expensive mistake to rectify. For anything of sentimental or financial value, hiring a specialist ensures a flat, bubble-free finish.

Choosing the Right Tradesperson

• Check Portfolios: Look for "before and after" photos of similar wood types (e.g., if you have teak, ensure they know how to handle oily timbers).
• Insurance: Ensure they hold Public Liability insurance, especially if they are working inside your home or transporting your furniture to a workshop.
• Questions to Ask:
  • Will you be stripping the wood chemically or just sanding?
  • What type of finish do you recommend for high-use dining (e.g., heat and alcohol resistance)?
  • How do you manage dust control in a domestic environment?
  • Do you offer a guarantee against the finish peeling or clouding?

UK Regulations

• VOC Regulations: Professional finishes must comply with UK REACH and VOC (Volatile Organic Compounds) limits to ensure indoor air quality.
• Waste Disposal: Old finishes, especially from pre-1960s furniture, may contain lead. Professionals must dispose of chemical waste and contaminated sanding dust according to the Environmental Protection Act.
• Health and Safety: If work is done on-site, the tradesperson should provide a COSHH (Control of Substances Hazardous to Health) assessment if requested for the chemicals used.

Common Problems

• Dust Contamination: Tiny particles landing in wet varnish create a "gritty" texture. Professionals use tack cloths and sealed environments to avoid this.
• Fish-Eye/Bubbling: Often caused by silicone contamination (from household polish like Pledge) or improper mixing. This requires the coat to be stripped back and started again.
• Clouding (Blooming): This occurs when moisture is trapped under the varnish, usually due to high humidity during application.
• Uneven Staining: Blotchy patches can appear if the wood isn't prepped with a grain filler or conditioner, particularly on softwoods like pine.

Frequently Asked Questions

Can you change the colour of my table during revarnishing?

Yes. Once the old finish is stripped back to bare wood, a stain can be applied to lighten, darken, or change the tone (e.g., turning orange-toned pine into a modern walnut shade) before the protective varnish is applied.

Is modern varnish heat resistant?

Most professional-grade polyurethane and AC lacquers are highly resistant to heat and liquids. However, they are not heat-proof; we still recommend using coasters and heat mats for items straight from the oven.

Can the work be done in my dining room?

Yes, many professionals offer on-site refinishing. They will use "tenting" and dust extraction to protect your home. However, for very large jobs or those requiring spraying, the table may need to go to a workshop.

How do I clean a newly varnished table?

Avoid silicone-based aerosol polishes. Use a slightly damp, lint-free cloth followed by a dry microfibre cloth. For stubborn marks, a very weak solution of pH-neutral dish soap is sufficient.

Why is my old varnish sticky?

This is usually "finish failure" caused by a build-up of household cleaning fats or UV degradation of the old lacquer. The only permanent fix is to strip the table back to bare wood and revarnish.
