# Paint Coverage Calculator MCP

> Paint Coverage Calculator estimates paint volume for any project. You calculate precisely how much paint you need by factoring in surface area, material texture, and the number of coats required. It accurately determines net paintable space after deducting openings like windows and doors.

## Description

Painting a room isn't just pouring paint on walls; it’s a calculation. This MCP estimates exactly how many gallons or liters you need for any job. You determine the actual surface area that needs coverage by accounting for cutouts, like window frames and door jambs. Next, you find out the specific coverage rate—is your wall smooth or rough? Is your paint economy grade or professional quality? Knowing this yield prevents buying too much (or too little). Finally, running those figures through our calculator determines the total volume needed after accounting for multiple coats. It's simple math that saves a trip to the hardware store and a massive headache on renovation day. With Vinkius managing the catalog, you connect once from any MCP-compatible client and get access to this tool alongside thousands of others.

## Tools

### calculate_net_area
Finds the total square units of surface that actually need paint after subtracting windows and doors.

### calculate_required_volume
Computes the total liquid volume needed to complete the entire painting project.

### lookup_surface_yield
Retrieves the standard coverage rate based on whether the surface is smooth or rough and what grade of paint you use.

## Prompt Examples

**Prompt:** 
```
I have 50 sqm of walls and 20 sqm of ceiling. There are 5 sqm of windows. How much area do I need to paint?
```

**Response:** 
```
The net paintable area is 65 square units.
```

**Prompt:** 
```
What is the standard yield for Premium paint on a Smooth surface?
```

**Response:** 
```
The standard coverage rate for Premium paint on a Smooth surface is 12 square units per liter.
```

**Prompt:** 
```
I need to paint 100 sqm with 2 coats. The paint yield is 10 sqm/L. How many liters do I need?
```

**Response:** 
```
You will need 20 liters of paint for this project.
```

## Capabilities

### Find actual paintable surface area
The system subtracts non-paintable openings (windows, doors) from a total area measurement.

### Determine standard coverage rate
It retrieves the expected yield of paint based on both the wall's surface texture and the specific grade of paint used.

### Calculate project volume requirement
The tool aggregates the area, yield, and desired coats to output a precise total liquid volume measurement.

## Use Cases

### Renovating a living room with mixed surfaces
The owner asks their agent, 'I have 150 sqm of walls, 30 sqm of ceiling, and 15 sqm of windows. The surface is standard, and I'm using Premium paint for two coats.' The agent uses `calculate_net_area`, then checks the yield with `lookup_surface_yield` before finally calculating the volume needed via `calculate_required_volume`.

### Painting a commercial kitchen
The facility manager needs to paint multiple rooms. They feed the total dimensions into `calculate_net_area`, then tell the agent they need enough paint for three coats, letting the system handle the rest of the yield calculations.

### Calculating a small bathroom repaint
A homeowner wants to know if they need two gallons or three. They check `lookup_surface_yield` first to confirm their paint grade is accurate, then use that figure along with the dimensions in `calculate_net_area` and finally nail down the total using `calculate_required_volume`.

## Benefits

- Saves money by preventing over-purchasing. Using `calculate_net_area` means you only account for the walls and ceilings that actually require coverage, not the windows or doors.
- Reduces project delays. By using `lookup_surface_yield`, you factor in surface texture (like rough stucco vs. smooth drywall) so your calculation is based on reality, not assumptions.
- Minimizes waste. The final output from `calculate_required_volume` gives you a single number: the exact liters needed for all coats, making material ordering straightforward.
- Better budgeting. You get clarity up front. Knowing the precise volume required helps manage costs across large-scale renovation jobs.
- Streamlines planning. Instead of manual measurements and complex spreadsheets, your agent runs these calculations instantly.

## How It Works

The bottom line is you move from guesswork about paint supply to a solid, actionable volume measurement.

1. First, you run `calculate_net_area` by providing the gross surface dimensions and listing all openings that won't be painted.
2. Next, use `lookup_surface_yield`, specifying the wall texture (e.g., Smooth) and paint grade (e.g., Premium) to get the standard coverage rate per liter.
3. Finally, input the net area and the number of coats into `calculate_required_volume` to receive the total liters needed.

## Frequently Asked Questions

**How do I calculate the area for my walls and ceiling?**
Use the `calculate_net_area` tool. Provide the gross wall area, the gross ceiling area, and any openings like windows or doors to get the net paintable area.

**Does surface texture affect how much paint I need?**
Yes. Rougher surfaces absorb more paint. You can use `lookup_surface_yield` to find the standard coverage rate for Smooth, Standard, or Rough textures.

**How do I know how many liters of paint to buy?**
Once you have your net area and the number of coats planned, use `calculate_required_volume` with the appropriate yield per liter to get the total volume needed.

**What units does the `calculate_net_area` tool accept when measuring surface dimensions?**
The tool requires all measurements to be in square meters (sqm). Ensure that every dimension for walls, ceilings, and openings is converted to sqm before running the calculation.

**If I use `lookup_surface_yield`, how do I handle specialty paint grades not listed?**
The calculator is based on standard industry yields. For specialized or unique paints, always check that product's specific data sheet first; the tool provides estimates for common professional grades.

**Are there rate limits when running `calculate_required_volume` multiple times?**
No, Vinkius supports high throughput for these calculations. You can run multiple volume estimates across different projects without hitting standard rate restrictions.

**What happens to my project data after I use the calculator's tools?**
Your specific measurements and calculation results remain private. Vinkius uses your inputs only to process the necessary calculations, never storing personal details long-term.

**When using `lookup_surface_yield`, how do I determine which surface type is appropriate?**
The best way to decide is to physically test or inspect the substrate. Use 'Standard' if unsure, but select 'Rough' for heavily textured masonry and 'Smooth' for drywall.
