General Details about Weathering Liquid

Water-soluble and translucent dye that makes things look dirty, old and weathered. Apply to a non porous surface like plastic, let dry, then smudge and wipe using a damp cotton bud or tissue to create great weathered effects. Wipe off a surface, but leave weathering liquid trapped in panel lines and projections such as stanchions making them look dirty. Weathering liquid will always be water soluble and will never fully harden. Being translucent means that it does not cover or obscure like an opaque paint. After weathering liquid has dried you can still see through it to the surface underneath.

* Rich concentrated colours that can be applied neat, straight from the pot using a paint brush or air brush spray.

* To weaken the colour, dilute with water or spirits. Dilute with water to make a colour wash or water colour paint that can be brushed on. You can add 4 or 5 times as much water as weathering liquid and get delicate shades. The more water used the lighter and fainter the shade gets. When water is added, weathering liquid dries more slowly. Dilute with spirits and the mixture dries fast leaving a water soluble matt surface coating.

* Use on many types of materials such as plastic, card, wood, plaster and metal.

* Before each use shake the pot until the ball bearing rattles, then shake for at least 15 seconds more. The liquid will be shiny if the pot is not full shaken. Shake again if the pot has been standing for more than a few minutes. The jar should be at room temperature, if the liquid is cold the dye will not mix properly.

Applying by Brush

Use like a paint. Apply straight from the pot using a brush.
Before use, test first on a hidden surface to check that it does not cause damage or staining. Even if a single application appears not to cause damage, multiple applications of liquid may cause damage. The liquid is a solvent and may discolour or strip paint, especially if applied heavily. Do not apply liquid on to unvarnished paintwork, or unvarnished printed surfaces.
To make brick joints, recesses and panel lines look dirty, dilute the weathering liquid, 1 of liquid to 1 of water and apply by paint brush or cotton bud. Wait until dry, then wipe from the surface leaving some trapped. Paint on small areas of concentrated liquid to highlight areas.
To colour wash buildings, wagons, carriages and loco's, dilute using up to 5 of water to 1 of liquid. This dries to a barely visible coating, like a very faint stain. After drying, smudge using a cotton bud or kitchen roll.
For a rustic weathered effect on through coloured plastic wagons, paint on neat liquid straight from pot, let dry, then smudge using damp kitchen roll. The wetter to kitchen roll, the more will be removed. As noted above, the liquid is a solvent, so before use on paintwork test on a hidden surface first to check that it does not cause damage or staining.


Weathering liquid can be rewetted using just water, and smudged or wiped to create more realistic weathering effects, just like the Modelmates weathering spray cans. Smudge it to make rain staining or remove create highlighted areas.General Information:
Kitchen roll works really well for smudging because it is tough and absorbent. If dryer, less is removed - if wetter, more is removed. Hold damp kitchen roll against the dried liquid and smudge/wipe using a twisting motion.
Smudging only works on non-porous surfaces such as plastic. Porous surfaces such as card, plaster, timber, cast metal models and many painted and printed surfaces will sometimes absorb Modelmates and be permanently stained. Methylated spirits can sometimes remove stains that cannot be removed by water.
Modelmates is translucent and will not colour and obscure in the same way as a paint. The colour of a surface is often more dominant than the Modelmates colour.
Different background surface colours will change the appearance of the Modelmates colour.
Surfaces previously sprayed with a matt sealer, varnish or enamel may be permanently discoloured by Modelmates. This is because the dye gets trapped in the rough matt finish.


If you have a gravity feed airbrush (see image below), put 5 or 6 drops into the cup on top and use straight away. Use a little at a time. Apply under low pressure, perhaps 10 psi. Some of the liquid will bounce back off hard surfaces, always wear a good quality face mask when spraying and use a spray booth if possible, better still, why not spray outside. When airbrushing, dry liquid will bounce back off solid surfaces like plastic. Do not breathe vapour/ spray. Use only in well ventilated areas. Dilute the liquid with either water or methylated spirits. Diluting with water creates an interesting colour wash effect, but it can usually only be done once because water takes a long time to dry and will dilute any coats of weathering liquid sprayed earlier. Diluting with methylated spirits makes the spray dry more quickly. A fine, light spray will usually dry almost on contact with a surface and not dilute earlier coats of weathering liquid. Fine spray will allow coats to be built up, just like with the spray cans. The more that are applied, the darker the colour gets.To clean the airbrush, just rinse in warm water after use.

* Caution:  weathering liquid is a solvent and can damage some surfaces. To protect a surface, such as paintwork, apply a matt varnish spray before applying Weathering Liquid. Before use, always test on hidden surfaces to check that weathering liquid causes no damage or staining. Porous surfaces such as paper or unpainted plaster will absorb the ink and be permanently stained, however, the effect can look really good.
