Asian Paints Apex Ultima 20 Litre Price Per Litre Coverage and Cost Calculator

June 9, 2026

Summary

The key to budgeting for Asian Paints Apex Ultima isn't the 20L bucket price (around ₹5,800), but the effective cost of ~₹2.45 per square foot for a finished, two-coat wall.
For a typical 1,000 sq ft exterior, you'll need about 16.7 litres, meaning a single 20-litre bucket is sufficient for the complete two-coat system.
To ensure you get the full 8-year performance warranty, proper surface preparation with primer (like Asian Paints TruCare Exterior Wall Primer) is non-negotiable.

You searched for the Asian Paints Apex Ultima 20 litre price — and you'll find it in this article. But here's the thing: that number is only half the story.

The real question — the one that actually determines your total project budget — is: what is my effective cost per square foot of finished wall?

As homeowners and contractors across India have noted, "comparison of the brands is tough from online search due to so many options under each brand". And then there's the classic trap: you don't know your wall's sq ft, so you either over-buy or run out of paint mid-project with your painter standing idle. And if you go cheap to save money upfront? As one experienced painter put it bluntly — "they might cost you more in the long run as the durability is less."

This guide cuts through all of that. We'll give you a clear coverage calculator, a worked example for a standard 1,000 sq ft Bangalore exterior, and everything you need to budget your project with confidence.

The Apex Ultima Cost & Coverage Calculator

Stop guessing. The table below breaks down the true cost of each Apex Ultima variant — not just what you pay at the counter, but what you spend per square foot of finished, protected wall. That's the number that matters.

How to read this table: "Effective Cost per sq ft" accounts for the paint's price, its spread rate per litre, and the fact that a proper exterior finish requires 2 coats. This is your real budgeting number.

Variant	20L MRP (Indicative, Bangalore)	Spread Rate (sq ft/litre, per coat)	Coats Required	Effective Cost per sq ft (₹)
Apex Ultima	₹5,800	110–130 sq ft	2	~₹2.45
Apex Ultima Protek	₹12,644	~90 sq ft (top coat)	2	~₹7.02
Apex Ultima Protek Duralife	₹14,500	~90 sq ft (top coat)	2	~₹8.05

Prices are indicative and subject to change. For current prices and 60-minute delivery in Bangalore, check Asian Paints on HomeRun. Spread rate based on Asian Paints' official recommendations on average masonry surfaces. Actual coverage varies with surface porosity, texture, and application method. Effective cost = (Price per litre) ÷ (Spread rate ÷ 2 coats).

Why Cost Per Sq Ft Is the Only Metric That Matters

Think of it this way: judging paint by its 20L sticker price is like buying a car based on fuel tank size instead of mileage. The tank size tells you nothing about how far you'll actually go.

A paint with a higher spread rate covers more area per litre, meaning you buy fewer buckets for the same job. A paint with a lower per-litre cost but poor spread rate can end up costing you more overall — plus an extra trip to the store when you run short.

Several factors will influence the coverage you actually get on-site:

Surface porosity: New, unpainted plaster absorbs significantly more paint than a previously coated wall
Surface texture: Rough, sand-finished walls have a larger effective surface area than smooth walls
Application method: Brush application typically uses more paint than roller or spray
Dilution ratio: Always follow the manufacturer's specified dilution — incorrect dilution directly impacts coverage and paint film performance

Worked Example: Total Paint Cost for a 1,000 sq ft Bangalore Exterior

Let's make this real. You're painting the exterior of your Bangalore home. Total paintable wall area: 1,000 sq ft. Here's how to calculate your material cost for each variant.

Using Standard Apex Ultima

Step 1: Total coverage needed

1,000 sq ft × 2 coats = 2,000 sq ft of total paint application

Step 2: Litres of paint required

Apex Ultima covers approximately 55–65 sq ft per litre for the complete two-coat system. Using a practical average of 60 sq ft/litre:
1,000 sq ft ÷ 60 = ~16.7 litres needed

Step 3: Buckets to buy

One 20-litre bucket covers your entire 1,000 sq ft exterior with paint to spare.
Total material cost for paint: ₹5,800

Using Apex Ultima Protek (for comparison)

Protek's top coat covers approximately 45 sq ft/litre for the two-coat system
1,000 sq ft ÷ 45 = ~22.2 litres needed
You'd need one 20L bucket + one 4L bucket (~₹3,068)
Paint material cost: ~₹15,712 — plus the mandatory Protek Base Coat

The premium variants offer a longer warranty (Protek: 10 years vs Apex Ultima's 8 years) and superior protection. But the table above makes the cost difference transparent so you can make an informed call based on your building's age, location, and exposure to rain and sun.

Real talk from the community: "The paint is actually cheap — it's the labour that costs a lot." (Reddit). This is why getting your paint quantity right the first time matters so much. Running out mid-project doesn't just cost you another bucket — it means your painter is waiting.

What Is Asian Paints Apex Ultima? (Quick Product Brief)

Before you buy, here's what you're getting. According to the official Asian Paints product page:

Type: 100% acrylic weatherproof exterior emulsion
Technology: Advanced PU Serum technology for superior algae and fungus resistance
Warranty: 8-year performance warranty against weather damage
Finish: Luxurious sheen with excellent UV protection
Dirt Resistance: High Dirt Pick-Up Resistance (DPUR) keeps walls cleaner for longer
VOC: Meets LEED VOC criteria as per Indian Green Building Council (IGBC) standards

It's a genuinely premium product — and as users on the ground have confirmed, "Asian Paints Apex Ultima" is the go-to recommendation for Bangalore's tough combination of monsoon rains and harsh summer sun.

Application Is Everything: How to Get Your 8-Year Warranty

Here's a point the community is absolutely right about: "Just make sure the putty and primer work is done good. If not, no paint is gonna save you." (Reddit)

To get full 8-year performance from Apex Ultima, follow this application sequence:

Surface Prep: Remove all dust, grease, laitance, and any loose or flaking old paint. Treat efflorescence with a dilute acid wash.
Crack Filling: Fill hairline cracks and surface defects with an appropriate filler or putty. For exterior walls, use Asian Paints TruCare Cement Wall Putty for a uniform base; check the latest wall putty price list to budget for this crucial step.
Sanding: Sand the surface to even out the filler and ensure a smooth, consistent substrate.
Primer — 1 Coat: Apply one full coat of Asian Paints TruCare Exterior Wall Primer (dilute 90–110% with water). Check our wall primer price list for current rates. Allow to dry completely — typically 4–6 hours.
Top Coat — 2 Coats: Apply two coats of Apex Ultima. Dilute with maximum 40% water. Allow 4–6 hours drying time between coats.

Skipping the primer coat is the single most common reason premium exterior paint underperforms. The primer seals the surface, ensures adhesion, and is what actually activates the full warranty protection.

Get Genuine Apex Ultima Delivered to Your Bangalore Site in 60 Minutes

Here's a frustration that's all too common on Bangalore job sites: the painter shows up, you realise you're short by a bucket, and now you're burning an hour (and paying idle labour) to track down the right variant from a local hardware store — only to wonder if what you're getting is the genuine article.

Your Takeaway: Budget by Square Foot, Not by Bucket

The next time you're planning an exterior paint project, resist the urge to judge paint by the price printed on the bucket. Run the numbers:

Measure your paintable wall area in sq ft
Look up the spread rate for the variant you're considering
Divide area by spread rate to get litres needed
Multiply litres × price per litre = your real material cost

For most standard Bangalore exteriors in the 800–1,200 sq ft range, one 20-litre bucket of Apex Ultima will handle the job. Factor in one bucket of exterior primer and a bag of wall putty, and you have a complete, warranty-backed exterior paint system — ready to face the next eight monsoon seasons.

Frequently Asked Questions

What is the price of a 20L bucket of Asian Paints Apex Ultima?

The indicative MRP for a 20-litre bucket of Asian Paints Apex Ultima is around ₹5,800 in Bangalore. However, the true cost of your project depends on the "effective cost per square foot," which is approximately ₹2.45 for a standard two-coat application. This metric is more important as it accounts for the paint's coverage area, giving you a more accurate budget.

How many square feet does a 20 litre bucket of Apex Ultima cover?

A 20-litre bucket of Asian Paints Apex Ultima will cover approximately 1,000 to 1,200 square feet of wall area for a complete two-coat system. The paint's spread rate is 110–130 sq ft per litre for a single coat. Since two coats are required for proper protection and warranty, the effective coverage is about 55-65 sq ft per litre for the full job.

Why is Apex Ultima Protek so much more expensive?

Apex Ultima Protek is more expensive because it offers superior technology, a longer performance warranty, and enhanced protective features. While standard Apex Ultima comes with an 8-year warranty, the Protek series offers up to a 10-year warranty, advanced damp-proofing, and crack-bridging capabilities, justifying its premium price for buildings requiring maximum protection.

Do I really need to use a primer before applying Apex Ultima?

Yes, using a primer is essential to get the full 8-year performance warranty and durability from Apex Ultima. A coat of Asian Paints TruCare Exterior Wall Primer seals the surface, ensures proper adhesion of the topcoat, and prevents issues like flaking or uneven finish. Skipping primer is a common mistake that significantly compromises the paint's lifespan.

What is the correct mixing ratio of water for Apex Ultima?

You should dilute Asian Paints Apex Ultima with a maximum of 40% water (400ml of water for every 1 litre of paint) for application. Following the recommended dilution ratio is crucial for achieving the specified coverage area and ensuring the paint film performs as designed. Incorrect dilution can lead to poor coverage and reduced durability.

How do I calculate the total paint needed for my house?

To calculate the total paint required, first measure the paintable exterior wall area of your house in square feet (length x height, minus windows/doors). Then, divide this area by the paint's effective two-coat coverage rate (around 60 sq ft/litre for Apex Ultima). For a 1,000 sq ft house, you would need approximately 16.7 litres, making one 20-litre bucket the perfect amount.
