Non-Darkening Sealer for Anti-Graffiti PaintPre anti graffiti paint sealing coat

Anti Graffiti Paint - Graffiti Magic Graffiti Magic™ Non-Darkening Sealer is a clear 100% acrylic sealer dispersed in water making it low odour, non-flammable and low toxicity.

Used as a transparent sealer for porous surfaces, such as, brick, mortar, concrete, render, porous stone and bare timber prior to application of Graffiti Magic Anti-Graffiti Paint.

It is used to avoid darkening the original surface - for example bricks may not show any darkening when an anti-graffiti coating is applied but the mortar may do.

It is not required over sealed or previously painted surfaces.

Also suitable for sealing sandstone and other natural stone products against the ingress of water reducing mould and mildew discolouration.

Can also be used as a general non darkening sealer for concrete and concrete products such as cement render, mortars and grouts, fibro cement, etc.

To test the effect of Non-Darkening Sealer on a surface we strongly recommend a small discrete trial application be carried out.


Non Darkening Sealer

5 Litre Container   £45.00(ex vat)




Water based: more environmentally friendly and can be applied to damp surfaces.
Adhesion: excellent adhesion to concrete and most common building surfaces.
Excellent durability: resists mould and mildew discolouration.
Water resistant: reduces water penetration on porous surfaces.
Stain resistant: improved resistance to oil, petrol and mild chemical stains.

Spread Rate

10 to 12m2/Litre depending on density of concrete surface.


Application is by brush, spray or roller.

Apply one good coat of Non Darkening Sealer over a clean, dry substrate - first ensuring that any brick acid/etch cleaner used has been thoroughly rinsed off.

Non Darkening Sealer is milky white when first applied but dries clear.

For Non Darkening Sealer to work it is important that it be allowed to dry fully before applying any Graffiti Magic finishing coats. Allow at least 4 hours under good drying conditions, but preferably overnight.

Important: Avoid using a paint brush when applying Graffiti Magic Non Darkening Sealer to surfaces subjected to efflorescence (i.e. salt deposits on cement substrates). Efflorescence can be difficult to detect on light coloured surfaces and will produce a milky effect on a clear finish if disturbed during application (i.e. by shear action of using a brush). Roller or spray application is recommended where efflorescence may be present.
