Common Mistakes to Avoid When Choosing Kitchen Plywood
Ignoring moisture resistance
Kitchens see constant exposure to steam, spills and humidity. Using MR-grade plywood instead of BWR or BWP grade is one of the most common mistakes homeowners make, leading to swelling and delamination over time.
Choosing thickness on price alone
Thinner panels cost less upfront but sag and warp faster under the weight of utensils and appliances. For cabinet carcasses, 18-19mm is usually the safer choice.
Overlooking the core quality
Two sheets can look identical on the surface but have very different core construction. Always ask for the grade certification and check for uniform, gap-free layers.
Skipping the edge banding
Exposed plywood edges absorb moisture fastest. Proper PVC or laminate edge banding on every cut edge keeps water out and extends the cabinet's life significantly.
Frequently Asked Questions
1. Which plywood grade is best for a kitchen?
BWP (Boiling Waterproof) or Marine grade is recommended for kitchens because of constant moisture and steam exposure.
2. Is 18mm plywood enough for kitchen cabinets?
Yes, 18-19mm is the standard thickness for cabinet carcasses and shutters in most modular kitchens.
3. Does edge banding really matter?
Yes. Unsealed edges are the most common entry point for moisture, so proper edge banding significantly extends the life of the cabinet.
