We get a lot of questions about chalk finish paint — from complete beginners wondering where to start, to experienced painters troubleshooting a specific problem. Here are the most common questions we get, answered honestly.

Do I need to sand before using chalk paint?

Not heavily. A light scuff sand with 180 grit is all you need on most surfaces — you're just dulling the surface to give the paint something to grip, not stripping the existing finish. The exception is waxed surfaces, which must have the wax removed before painting. More on painting over waxed surfaces here.

Do I need to prime before using chalk paint?

Usually not. Artisan Chalk Finish Paint adheres to most surfaces with just a clean and scuff sand. The exceptions are very high-gloss surfaces (use a bonding primer), oily timbers like teak (use a shellac-based primer), and very dark surfaces where you're painting a light colour (use a blocking base coat). More on painting light over dark here.

How many coats of chalk paint do I need?

Two coats is the standard for most projects. The first coat seals the surface and provides a base; the second coat gives full, even coverage. On very dark surfaces or very porous timber, a third coat may be needed. Always sand lightly with 220 grit between coats.

Do I need to seal chalk paint?

Yes — always. Chalk finish paint is porous and will mark, stain and wear without a protective topcoat. Wax is the traditional sealer for chalk paint and gives a beautiful soft finish. For high-use pieces — dining tables, kitchen cabinets, children's furniture — use a durable water-based sealer or polyurethane instead. Full sealing guide here.

Can I use chalk paint on laminate furniture?

Yes, with the right prep. Laminate is non-porous, so you need to scuff sand more thoroughly than on timber and apply a bonding primer before painting. Artisan Mineral Paint is actually a better choice for laminate — its primer-blocker-paint formulation gives better adhesion on difficult surfaces. Full laminate guide here.

Can I use chalk paint on outdoor furniture?

We don't recommend it. Chalk finish paint is formulated for interior use and will fade and deteriorate quickly outdoors. For outdoor furniture, use Artisan Mineral Paint, which has built-in UV protection and water resistance. Full outdoor furniture guide here.

Why is my chalk paint streaky?

Streakiness is usually caused by one of three things: paint applied too thickly, going back over paint that's started to dry, or a brush that's too dry. Apply thin coats, work confidently without going back over drying paint, and make sure your brush is adequately loaded. Sanding between coats also helps significantly.

Why is my chalk paint peeling?

Peeling is almost always a prep issue. The most common causes: the surface wasn't cleaned properly (grease or wax residue), the surface wasn't sanded, or the paint was applied over a waxed surface. How to fix peeling paint on furniture.

Can I mix chalk paint colours?

Yes — Artisan Chalk Finish Paint colours can be mixed together to create custom colours. Mix within the same range (chalk finish with chalk finish, mineral with mineral) for the best results. Keep a note of your ratios so you can recreate the colour if you need more. Full colour mixing guide here.

How long does chalk paint take to dry?

Artisan Chalk Finish Paint is dry to touch in approximately 30–60 minutes under normal conditions (20–25°C, moderate humidity). Allow 1–2 hours between coats. The paint is fully cured after 7–14 days — treat the piece gently during this period.

Can I use chalk paint on fabric or upholstery?

Yes — chalk finish paint can be used on fabric and upholstery, diluted with water to a thin, milky consistency. It gives a matte, slightly stiffened finish. This is a specialist technique — test on an inconspicuous area first and be aware that the fabric will feel stiffer after painting.

How much chalk paint do I need?

A 250ml tin covers approximately 3–4 square metres (enough for a small piece or one coat on a medium piece). A 1 litre tin covers approximately 12–16 square metres (enough for most medium to large pieces in two coats). When in doubt, buy slightly more than you think you need — having leftover paint for touch-ups is always useful.

What's the difference between chalk paint and chalk finish paint?

"Chalk paint" is a generic term that's become widely used to describe any flat matte furniture paint. "Chalk finish paint" is more accurate — it describes the finish (chalk-like, flat matte) rather than the ingredients. Artisan Paint Company calls their range "Chalk Finish Paint" for this reason. The terms are used interchangeably in practice.

Is chalk paint the same as regular paint?

No — chalk finish paint is specifically formulated for furniture, with higher pigment load, better adhesion to smooth surfaces and a flat matte finish that regular wall paint can't replicate. Full comparison here.
