Outline Cap

From £0.22

The Outline Cap is a versatile spray paint cap designed to deliver clean, controlled lines, making it one of the most widely used and essential caps for graffiti artists, muralists and creative professionals. Recognised as a true all-rounder, the Outline Cap is compatible with most 400 ml spray paint cans and is particularly suited for use with brands such as MTN, Loop, Molotow and Flame. Producing an average spray width of around 1–4 cm depending on the pressure and distance applied, it is perfect for outlining, detail work and medium-sized fills. Its balanced spray output offers excellent control while maintaining good coverage, making it a go-to choice for both beginners and experienced writers.

Medium Spray Width (1–4 cm): Provides controlled, versatile lines ideal for outlines and medium fills.
All-Round Performance: Works equally well for detail work, outlines or general-purpose spraying.
Wide Compatibility: Fits most standard spray paint cans, including MTN, Loop, Molotow and Flame.
Balanced Output: Offers a steady, consistent flow of paint without excessive drips or overspray.
Reliable for All Skill Levels: Easy to use for beginners while offering precision for experienced artists.

How to Use

Attach the Outline Cap firmly onto your spray can, then shake the can well before spraying to mix the paint. Hold the can at a consistent distance and apply smooth, steady movements to achieve clean lines or medium-width fills. Adjust your pressure and distance to vary the line thickness between approximately 1 and 4 cm. After use, clear the cap by spraying briefly upside down to prevent clogging and maintain consistent performance for future sessions.

Real professionals who keep their word

My order arrived with the box opened and products missing. I contacted the store by email and they responded very quickly. They called me personally and assured me the missing items would arrive the next day, along with a small gift as compensation.

Cheapest paint store

Cheapest paint store I've found. Two free cans when you order over £40, crazy deals on pens at the moment. Every time I order they pack in a fredo too, which gets me excited not going to lie.

So fast! 20 hours to ship a 20kg package!

Ten out of Ten! All present and correct and a couple of free cans and stickers and the paint was delivered barely 20 hours after the order was made. What more could you ask for?

So much better than elsewhere

So much better than the main competitor (you know the ones). Always get my paint on time (unlike the competitor who take a week to ship it out sometimes). Alfreshco Dave is the man!
