Canterbury Spar Pebble Dash: Colour, Size & Alternatives

Canterbury Spar is a multicoloured stone used to create a pebble-dash finish on exterior walls. It usually combines pink or salmon tones with white and grey stones and darker flecks, although the mix varies between suppliers. GravelMaster no longer stocks Canterbury Spar, but this guide will help you recognise it and find a suitable match for an existing wall.

What is Canterbury Spar pebble dash?

Canterbury Spar is the stone you see on the surface of a Canterbury pebble-dashed wall. In a dry-dash finish, the aggregate is applied to fresh render to create the wall’s colour and texture. You may also see this type of finish called spar dash.

If you are repairing an existing wall, the name alone is not enough to identify a match. Canterbury Spar products from different suppliers can vary in their stone mix and grading, so compare the material itself before choosing one.

What colour is Canterbury Spar?

Canterbury Spar is generally a lively mix of salmon pink or pink, white and grey, with some darker stones. Depending on the supplier, you may also see red or brown tones. It has a more varied appearance than a plain white or cream pebble dash.

Look at the whole wall rather than picking out one stone. The proportions of each colour affect the overall finish, and the render visible between the stones can change how light or dark it appears. Loose stone may also look different when wet, so compare samples in natural daylight and, if possible, against a clean area of the existing wall.

What size is Canterbury Spar?

There is no single size shared by every Canterbury Spar product. Suppliers list examples graded from 3–8mm, as well as products described by 5mm or 8mm grades. Always check the specification of the material you are considering.

For a repair, size matters alongside colour. A patch made with noticeably larger or smaller stones can stand out even when the colour mix looks close. Compare a sample with the stones already set into the wall, rather than relying on the product name.

How can you match Canterbury Spar on an existing wall?

Start by looking at a clean, undamaged part of the finish. Compare three things: the apparent stone size, the balance of pink, white and grey, and the colour of the background render. An older wall may have weathered, so a fresh sample can appear brighter than the existing finish.

If a supplier offers a sample, hold it against the wall outdoors and view it from both close up and a few steps back. This gives you a better sense of how the mix will look across a repaired area. For a larger repair, ask the person carrying out the work to check that the chosen aggregate is suitable for the render system as well as visually similar.

Is Canterbury Durite the same as Canterbury Spar?

Canterbury Durite is a particular product sold for the same type of pebble-dash finish. Other Canterbury Spar products may differ in stone size and colour mix. If you are matching an existing wall, compare a sample in natural light before choosing—the names alone will not tell you whether the finish will match.

Can Canterbury Spar be used as garden gravel?

Some suppliers also list their Canterbury Spar products for decorative garden use. Check the guidance for the particular stone and where you intend to lay it. Fine dashing aggregate used as a loose surface will behave differently from larger chippings chosen for a path or driveway.

The reverse matters too: a garden gravel with similar colours is not automatically suitable for pebble dashing. Stone size, grading and the supplier’s stated uses all need to be considered before applying an aggregate to a rendered wall.

What are the alternatives to Canterbury Spar?

If you are matching a pebble-dashed wall, look for a purpose-made dashing aggregate with a similar size and colour balance. Compare a sample with the existing finish and check that the supplier recommends it for your intended application. A colour match alone is not enough.

If it is the pink, white and grey look you want for a garden path or border, Flamenco Gravel 20mm is one landscaping option to consider. It is a different, larger product and should not be treated as a replacement for Canterbury Spar on a wall. You can also compare colours and sizes in GravelMaster’s Gravels & Chippings range.

Frequently asked questions

Does GravelMaster sell Canterbury Spar?

No. GravelMaster no longer stocks Canterbury Spar dashing blend. For an existing pebble-dashed wall, look for a current dashing product whose specification and sample suit the repair.

Does Canterbury Spar look different when wet?

It can. Wet stone may show stronger colours than dry stone, and loose material can look different from a finished wall. View a sample in the conditions that matter to you before making a choice.

Can ordinary decorative gravel replace Canterbury Spar on a wall?

Do not assume it can. A similar colour does not establish that garden gravel has the right size, grading or suitability for a pebble-dash finish. Check the product guidance for wall use.

How do I choose a close match for an existing finish?

Compare a physical sample with a clean section of the wall. Look at the stone size, the proportion of each colour and the background render. Check the proposed aggregate’s suitability with its supplier or the person carrying out the repair.
