    • Which paint is the most suitable for farm equipment?

      Ralston Solvent Industrial High Gloss is a hard-wearing primer and coating for metal. Thanks to its corrosion-resistant properties it is an excellent finish for farm equipment. It is also recommended for steel fencing and boats above the waterline.

    • Which primer can I use on metal and plastics?

      Ralston Solvent Uni-Primer ensures good adhesion on almost all metals and plastics (except stainless steel, PE and PP). It is also a suitable adhesive primer for plastic sheeting such as Trespa. It is quick drying and repainting time is short. Available in all colours. 

    • What product can I use as an adhesive primer on plastic sheeting, for example, Trespa?

      Ralston Solvent Uni-Primer is recommended for Trespa and suchlike materials. It is quick drying and repainting time is short. Remove oil or grease from the substrate and sand lightly. On plastic, one coat is sufficient to ensure good adhesion. 

    • Is there an exterior wall paint that is resistant to algae and moss growth?

      Ralston Exterior Siloxan Mat is recommended for facing walls, masonry, plaster and concrete. Good resistance to algae and moss is one of its properties. The paint is water-repellent and has excellent outdoor durability and weatherproof performance. Due to the specific properties of this product there is less risk of damp walls and frost damage. 

    • What product can I use as an adhesive primer on plastic sheeting, for example, Trespa?

      Ralston Solvent Uni-Primer is recommended for Trespa and suchlike materials. It is quick drying and repainting time is short. Remove oil or grease from the substrate and sand lightly. On plastic, one coat is sufficient to ensure good adhesion.

    • How long is the shelf life of paint?

      Our (wall) paints generally have a maximum period of 12 months for which it may be used (in an undamaged original packaging). This does not mean that the paint would not be suitable to paint. If a paint is kept cool and frost-free, than it would be usable for many years.

      By using the solvent based paints, the drying time will be somewhat longer. This is due a functional decline of dryers (drying stimulating substances) in the paint.

      Water based (wall) paints can smell amazingly bad over time. When this is the case, the paint is no longer usable.

      The paint must always be stirred well before use. If the paint has not been used for a long time, it must be stirred well in order to be homogeneous. The solid constituents of the paint drop over time to the bottom of the tin or bucket. Do you notice that these constituents at the bottom no longer can be stirred? If this is the case, then the paint is absolutely not suitable for painting.

      It is possible that a skin formation takes place in the paint when the packaging is open. Thus, it makes the painting dries as a result of its reaction with the oxygen. You should always close the tin of paint well. So, it is important to avoid damaging the cover or the closure of the paint bucket while using it. Putting the paint can upside down can also provide a solution. The entry of oxygen through the closure of the paint bucket is thereby prevented.

      Are the storage conditions of paint met? Then, we guarantee a usage period of 12 months. This means, as indicated, that you should take into account that the quality of paint decreases over time.

      Finally, it is advisable to always put on a test piece when you are going to use the ´old´ paint. If the paint is easy to apply, dries satisfactorily and gives the desired result, you can still use the paint.

    • What is required in the long-term storage of a used paint brush?

      • Start with cleaning the in paint covered brush bristles, with turpentine in a big glass jar.
      • If the paint on the brush is largely dissolved, pick up the brush and hold it steady between your hands. Start rolling the brush back and forward. Keep the lower parts of the brush and the brush bristles in the jar.
      • After that, rinse the, nearly dry brush, with clean turpentine in another glass jar.
      • After this, dry the brush by rolling it back and forth in your hands, keeping it in the glass mayonnaise jar.
      • Then, wash the clean brush bristles with soft soap and rinse the brush bristles with clean water.
      • Then again, dry the brush by rolling it back and forth in a glass jar by holding the brush steady between your hands.
      • After this, roll the paint brush in paper towel, bind it with a rubber band and tape it, to avoid getting dust in the brush. Then store it in a dust-proof storage.
      • Now the paint brush is clean, dust-proof and ready to be used for a next paintjob.
      • Add the turpentine, used for rinsing the brush, to the turpentine in the mayonnaise jar.
      • Seal the jar filled with turpentine, and let the paint residues settle in the jar.
      • The inflated turpentine in the mayonnaise jar can be used again for a new first cleaning of a paint brush.
      • Let the settled paint residues in the jar dry and dispose it as (gray) waste.

      What is required when storing a paint brush that is frequently used?

      • Put the paint brush with its brush bristles, halfway into the water or even better in raw linseed oil.
