Figuring Out Paint for Kitchen Cabinets: The Basics
The amount of paint you’ll need for your kitchen cabinets depends on several factors. Let’s break down the key elements that influence your cabinet paint quantity estimator.
Paint Coverage: What to Expect
Every type of paint has a different coverage rate, usually listed on the can. This tells you how many square feet one gallon of paint can cover.
- Typical Coverage: Most quality cabinet paints cover between 350 to 400 square feet per gallon. However, this can vary.
- Factors Affecting Coverage:
- Paint Type: Latex, oil-based, and enamel paints can have different coverage rates.
- Surface Texture: Smooth surfaces generally require less paint than textured ones.
- Application Method: Spraying might use more paint than brushing or rolling due to overspray.
- Number of Coats: Most cabinet refinishing projects require at least two coats for a durable and even finish.
Surface Area Calculation: The Foundation
The most important step in determining how much paint for kitchen cabinets is calculating the total surface area you’ll be painting. This includes:
- Cabinet Doors: Measure the height and width of each door. Multiply these dimensions to get the area of one door. Then, multiply by the total number of doors. Don’t forget to account for both sides of the doors if you plan to paint them.
- Cabinet Drawer Fronts: Measure the height and width of each drawer front. Multiply for the area of one, then multiply by the total number of drawer fronts. Again, consider painting both sides if applicable.
- Exposed Cabinet Sides: Measure the height and width of any cabinet sides that will be visible when the doors are closed.
- Cabinet Frames/Face Frames: These are the visible parts of the cabinet box that the doors attach to. Measure the length and width of these sections.
Tip: Use a simple tape measure for accurate measurements. It’s always better to be slightly generous with your measurements to avoid running out of paint.
Estimating Paint for Kitchen Cabinets: A Practical Approach
Let’s walk through a practical example to illustrate the cabinet paint volume calculation.
Imagine a kitchen with:
- 20 cabinet doors (12″ x 30″ each)
- 5 drawer fronts (6″ x 24″ each)
- 2 exposed cabinet sides (24″ x 36″ each)
- 10 linear feet of face frame (average 3″ width)
Calculation Steps:
-
Cabinet Doors:
- Area of one door = 12 inches * 30 inches = 360 square inches
- Total area of 20 doors = 360 sq in * 20 = 7,200 square inches
- Convert to square feet: 7,200 sq in / 144 sq in/sq ft = 50 sq ft
-
Drawer Fronts:
- Area of one drawer front = 6 inches * 24 inches = 144 square inches
- Total area of 5 drawer fronts = 144 sq in * 5 = 720 square inches
- Convert to square feet: 720 sq in / 144 sq in/sq ft = 5 sq ft
-
Exposed Cabinet Sides:
- Area of one side = 24 inches * 36 inches = 864 square inches
- Total area of 2 sides = 864 sq in * 2 = 1,728 square inches
- Convert to square feet: 1,728 sq in / 144 sq in/sq ft = 12 sq ft
-
Face Frames:
- Face frames are typically measured in linear feet. A common rule of thumb is that 1 linear foot of face frame (at a standard width) might equate to roughly 1 square foot of surface area for painting.
- Total area of face frames = 10 linear feet * 1 sq ft/linear ft = 10 sq ft
-
Total Surface Area:
- Total area = 50 sq ft (doors) + 5 sq ft (drawers) + 12 sq ft (sides) + 10 sq ft (face frames) = 77 sq ft
Now, let’s factor in coats and coverage:
- Assume you need 2 coats of primer and 2 coats of paint (total of 4 coats).
- Assume your paint coverage is 350 sq ft per gallon.
Paint Needed for One Coat: 77 sq ft / 350 sq ft/gallon = 0.22 gallons
Paint Needed for Four Coats: 0.22 gallons * 4 coats = 0.88 gallons
Recommendation: Always round up to the nearest whole or half gallon. In this case, you would likely need 1 gallon of primer and 1 gallon of paint.
Using a Paint Calculator for Cabinets
Many paint brands and home improvement websites offer a paint calculator for cabinets. These tools are incredibly helpful. You input the dimensions of your doors, drawers, and cabinet boxes, and the calculator estimates the amount of paint needed.
These calculators often factor in:
- Standard paint coverage rates.
- The number of coats typically recommended.
- Sometimes, they even allow you to specify the type of finish or application method.
How to Use a Paint Calculator:
- Gather Your Measurements: Have all your cabinet dimensions ready.
- Visit a Reputable Site: Look for calculators on major paint brand websites (e.g., Sherwin-Williams, Benjamin Moore) or large home improvement retailers.
- Input Data Carefully: Enter your measurements accurately.
- Review the Estimate: The calculator will provide an estimated quantity. Again, it’s wise to round up slightly for any touch-ups or unforeseen needs.
Factors Influencing Paint Amount for Cabinet Refinishing
Beyond the basic surface area, several other elements can affect how much paint you’ll need for your kitchen cabinet painting project.
Number of Coats: The Key Determinant
This is perhaps the biggest factor after surface area.
- Primer: Most cabinet refinishing projects benefit from at least one, if not two, coats of primer. Primer helps with adhesion, blocks stains, and creates a uniform base for your topcoat.
- Topcoat: Two coats of your chosen cabinet paint are standard for durability and a smooth, consistent color. In some cases, especially with lighter colors over dark cabinets, or if you’re using a paint with lower coverage, you might need a third coat.
Table: Estimated Gallons Based on Coats and Surface Area (assuming 350 sq ft/gallon coverage)
| Total Surface Area (sq ft) | 1 Coat (Gallons) | 2 Coats (Gallons) | 3 Coats (Gallons) | 4 Coats (Gallons) |
|---|---|---|---|---|
| 100 | 0.29 | 0.57 | 0.86 | 1.14 |
| 200 | 0.57 | 1.14 | 1.71 | 2.28 |
| 300 | 0.86 | 1.71 | 2.57 | 3.43 |
| 400 | 1.14 | 2.28 | 3.43 | 4.57 |
| 500 | 1.43 | 2.86 | 4.29 | 5.71 |
Note: Always round up to the nearest full or half gallon. For example, if a calculation shows 1.14 gallons for 2 coats, buy 1.5 gallons.
Type of Paint and Finish
Different types of paint have varying coverage.
- Water-based (Latex/Acrylic) Paints: Typically offer good coverage and are easy to clean up.
- Oil-based (Alkyd) Paints: Often provide a harder, more durable finish but can have a stronger odor and longer drying times. Their coverage can be similar or slightly less than water-based.
- Cabinet-Specific Paints: Many brands offer specialized cabinet paints formulated for durability, adhesion, and a smooth finish. These can sometimes have slightly different coverage rates.
Sheen: While sheen (satin, semi-gloss, high-gloss) doesn’t directly affect the amount of paint needed, it’s a crucial consideration for the final look. High-gloss finishes can sometimes show imperfections more readily, which might lead some people to opt for an extra thin coat for perfection.
Application Method
- Brushing and Rolling: This is the most common DIY method. Coverage is usually close to the manufacturer’s stated rate. You might use slightly more paint if you apply it too thickly.
- Spraying (HVLP Sprayer): Spraying can achieve a factory-like finish but often results in more paint being used due to overspray. You might need to factor in an extra 10-20% of paint when spraying compared to brushing/rolling.
Cabinet Style and Complexity
- Flat-Panel Doors: These are the easiest to paint and require less paint per square foot because there are no intricate details.
- Recessed Panel Doors: The recessed areas add a bit more surface area and can be trickier to get into consistently.
- Doors with Many Details (Molding, Glazing): Intricately detailed doors will have a larger surface area and may absorb more paint, especially in the crevices.
Color Change
- Lightening a Dark Color: If you’re painting dark cabinets a lighter color (e.g., dark wood to white), you’ll definitely need adequate primer to block the original color. You might also need an extra coat of paint to achieve full coverage and avoid the dark color showing through.
- Darkening a Light Color: This is usually less of an issue. A good primer is still essential, but you might get away with just two coats of the darker topcoat.
Determining Paint for Cabinets: A Step-by-Step Process
To ensure you have the right paint needed for cabinets, follow these steps.
Step 1: Measure Everything Accurately
This cannot be stressed enough. Get out your tape measure and measure every surface you intend to paint.
- Doors: Height x Width (for each side if painting both).
- Drawer Fronts: Height x Width (for each side if painting both).
- Cabinet Boxes: Measure visible sides, tops, and bottoms.
- Face Frames: Measure the linear feet.
Tip: Keep a notebook or use a spreadsheet to record all measurements. Label each measurement clearly (e.g., “Upper Cabinet Door 1,” “Bottom Drawer Front 3”).
Step 2: Calculate Total Surface Area
Add up all your measurements. Remember to convert inches to feet by dividing by 12 (for linear measurements) or square inches to square feet by dividing by 144 (for area measurements).
- Area of rectangles: Length x Width
- Convert inches to feet: Inches / 12
- Convert square inches to square feet: (Inches / 12) x (Inches / 12) OR Square Inches / 144
Step 3: Determine the Number of Coats
- Primer: Plan for at least one, but preferably two, coats of primer.
- Paint: Plan for two coats of your topcoat. If making a drastic color change or using a paint with lower coverage, consider three coats.
Step 4: Consult Paint Coverage Rates
Check the paint can or the manufacturer’s website for the stated coverage rate (e.g., 350 sq ft per gallon).
Step 5: Calculate Gallons Needed
Use the formula:
Total Surface Area (sq ft) x Number of Coats = Total Square Footage to Cover
Total Square Footage to Cover / Paint Coverage Rate (sq ft/gallon) = Gallons Needed
Example:
- Total Surface Area: 250 sq ft
- Number of Coats (Primer + Paint): 4 coats (2 primer, 2 paint)
- Paint Coverage: 375 sq ft/gallon
- Total Square Footage to Cover: 250 sq ft * 4 coats = 1,000 sq ft
- Gallons Needed: 1,000 sq ft / 375 sq ft/gallon = 2.67 gallons
In this scenario, you would need to purchase 3 gallons of paint (and potentially 1-2 gallons of primer, depending on your primer needs).
Step 6: Round Up and Account for Extras
It’s always better to have a little extra paint than to run out. Round up your calculated amount to the nearest half or full gallon.
- Consider Touch-Ups: Having extra paint is invaluable for future touch-ups if you scratch or scuff your cabinets.
- Application Method: If spraying, add an extra 10-20%.
- Complex Designs: If your cabinets have a lot of trim or detail, add a small buffer.
Buying the Right Kitchen Cabinet Painting Supplies
Choosing the right supplies is as important as calculating the paint amount.
Primer
- Purpose: Ensures adhesion, blocks stains, creates a uniform base.
- Type: Look for a high-quality, stain-blocking primer specifically designed for cabinets or furniture.
Paint
- Type: Opt for paints formulated for cabinets. These are typically durable acrylic enamels or oil-based enamels. They offer good adhesion and a smooth, hard finish.
- Sheen: Satin or semi-gloss are popular choices for cabinets as they are durable and relatively easy to clean. High-gloss offers a very slick look but can highlight imperfections.
Brushes
- Types:
- Angled Sash Brushes: Excellent for cutting in edges and painting detailed areas.
- High-Quality Synthetic Bristle Brushes: Good for latex or acrylic paints.
- Natural Bristle Brushes: Better for oil-based paints.
- Size: Have a few sizes on hand, like a 1.5-inch or 2-inch angled brush for precision and a larger brush for broader surfaces.
Rollers
- Types:
- Foam Rollers: Provide a very smooth finish, ideal for cabinet doors and drawer fronts.
- Microfiber Rollers: Offer excellent coverage and a smooth finish with fewer drips.
- Nap Size: A short nap (1/4″ or 3/8″) is best for smooth surfaces like cabinets.
Other Essential Supplies
- Painter’s Tape: For masking off areas you don’t want to paint.
- Drop Cloths: To protect your floors and countertops.
- Sanding Blocks and Sandpaper: For preparing surfaces (essential for adhesion!). Grit sizes 120-180 for initial sanding and 220-320 for between coats.
- Screwdriver/Drill: To remove cabinet doors and hardware.
- Cleaning Supplies: Degreaser (like TSP substitute), rags, buckets.
- Putty Knife and Wood Filler: For filling holes or dents.
- Caulk: To fill gaps between cabinet frames and walls.
- Paint Trays and Liners: For easy cleanup.
- Gloves and Safety Glasses: For protection.
Deciphering Paint Amount for Cabinet Refinishing: Common Pitfalls
Even with careful measurement, mistakes can happen. Here are common pitfalls to avoid when estimating paint for kitchen cabinets.
Underestimating Surface Area
- Problem: Forgetting to measure both sides of doors, or overlooking small cabinet sections.
- Solution: Be meticulous with your measurements. A second person can help ensure accuracy.
Ignoring the Need for Multiple Coats
- Problem: Thinking one coat will be enough, especially for drastic color changes.
- Solution: Always plan for at least two coats of paint, plus primer. This ensures durability and a professional finish.
Not Accounting for Surface Texture or Detail
- Problem: Assuming all surfaces paint the same. Textured surfaces or cabinets with intricate molding require more paint.
- Solution: Add a small buffer (5-10%) to your estimate if you have detailed cabinets.
Forgetting About Primer
- Problem: Skipping primer, especially when painting over dark colors or laminate.
- Solution: Factor in primer as a separate coat. Most projects benefit from 1-2 coats of primer.
Using Inaccurate Coverage Rates
- Problem: Relying on outdated or generic coverage rates.
- Solution: Always check the specific paint product’s label for its stated coverage.
Frequently Asked Questions (FAQ)
Q1: How much paint do I need if my cabinets are very large?
A1: For larger cabinets or a more extensive kitchen, you might need 2 to 3 gallons of paint. Always perform the surface area calculation as outlined above to get an accurate estimate.
Q2: Can I use leftover paint from another project?
A2: Yes, if it’s the correct type and color and in good condition. However, ensure you have enough for the entire project, including multiple coats and touch-ups. Mismatched batches can cause color inconsistencies.
Q3: Do I need a special type of paint for kitchen cabinets?
A3: Yes, it’s best to use a paint specifically designed for cabinets or high-traffic furniture. These paints offer superior durability, adhesion, and a smooth finish that can withstand frequent cleaning and use. Look for acrylic enamels or alkyd enamels.
