Our most frequently asked questions
There are a number of different reasons why a coating does not cure within the usual time frame.
To help speed up the process, the drying area should be well ventilated & warm; and drying may be accelerated by increasing booth temperature after spraying.
For minor water spotting problems, the best repair method is to polish the affected area(s). For major problems, you will need to sand smooth, then repaint. To prevent water spotting happening again, follow the recommended cure times before washing or exposing to rain; increase the spray booth temperature, and use a two pack paint system.
Liquid solvent becomes "trapped" in the paint film when the surface layer skins over too quickly, preventing their evaporation into the atmosphere. Solvents that vaporize within the paint film leave bubbles, pinholes or craters as they push through and "pop" the surface.
Solvents can be trapped due to:
There are a couple of different ways to repair Solvent Popping issues. For a minor problem, allow the finish to thoroughly dry/cure, sand smooth and refinish. Inspect surface carefully to ensure all craters have been removed. For a major problem, remove the affected film. Prime, seal and recoat, as necessary.

There are a number of ways you can prevent your paint from running or sagging.
See below our recommendations for prevention:
To prevent an orange peel effect on your paint surface, proper surface preparation is needed:
For the joinery industry, changing to water based is very straightforward. The drying times are not that different to solvent based and providing you have a dry filter spray booth at ambient temperature you will have no difficulty.All water based paint must be stored at above 5oC at all times.
If changing to water based paint for steel then you must look to invest in dry heating for both the spray booth and the drying area. The ideal temperature for water based painting on steel is 20oC. If moisture gets trapped under the surface of the paint, it causes significant problems. Please call our technical helpline on 01302 571503, for more information.
For 1 x 20 foot container, you will need approximately 15 litres of Ultrimax SG.
It is important to remove as much of the rust as possible with a wire brush or angle grinder. The best method is shot blasting to SA21/2 which removes the rust altogether. If the rust is still visable you can use Ultrimax Rustcoat which turns the rust back to clean metal. You can then overcoat with Ultriprime or similar product.
First, calculate the square area (metres) of the space that you are painting. Then, find out what the Theoretical Spreading Rate (TDS) is for your paint coating, which can be found on the Product Technical Data Sheet. Then divide your square area by the TDS, to give you the quantity of litre(s) you will need to cover the job.
This depends on the product. For water based paints, it is usually maximum 12 months. For solvent based paints - 24 months. Please check the Technical Data Sheet for the product used.
Please refer to the Technical Data Sheet for the correct thinners to use. Add as required, usually no more than 5-10% required by volume.
The paint coverage is only theoretical, and does not account for any loss due to product left in the paint tin, on brushes or rollers, and variations in the surface it is applied to. It is advisable to allow 20% loss factor when calculating paint coverage.

Yes we do. We have invested in advanced colour matching technology in our head office at Doncaster. Samples can be sent to us for colour matching.
Water based paints are usually slower drying but are very environmentally friendly and safe to use in confined places. They are low odour products but cannot be used for resistance to chemicals or solvents. Solvent based paints are quicker drying and many of them are resistant to chemicals, solvents, UV and have very anti-corrosive properties. It is difficult to get a very high gloss finish with a water based coating but easily achieved with solvent. The challenge with solvent based paints is the need for the correct respiratory protection and the fumes can be very strong. If large volumes of solvent are used there may be a need for compliant coatings due to VOC (Volatile Organic Compounds) regulations.
Alkyd Paints - Oxidative curing alkyd coatings, sometimes referred to as `Oil based coatings` have been used for thousands of years. Modern day alkyds are a combination of natural drying oils and synthetic resins. A benefit of alkyds is that they are single pack and easy to apply. A disadvantage is that they can be very slow to fully cure.
Epoxy Paints - These were first developed in the mid-to-late 1950`s and are now the most widely used industrial and marine protective coating. They are two-component coatings, packaged in separate containers. One container holds the epoxy resin and the other is the curing agent. Epoxies can be solvent-based, water-based or essentially solvent-free. Epoxies can also be used in powder coating. Epoxies have excellent adhesion, chemical resistance, water resistance and wet adhesion. The disadvantage is they are susceptible to chalking so not suitable as a topcoat outside.
Polyaspartic - Initially introduced in the 1990`s, they are technically an aliphatic polyurea and can be used to achieve very low VOC systems. Polyaspartics are now being used as finish coats to achieve film builds up to 380 microns in a single pass and achieve a high gloss level.
Polyester - These coatings are used in marine and joinery and are two component paints with a rather short pot life of approximately 40 minutes. Once cured they are very durable and can be used for tank linings, decks and to provide a high gloss finish for joinery.
Polysiloxane - These are used where there is heavy abrasion, chemicals, extreme UV or high temperatures. These are very expensive coatings but designed for long life.
Polyurethane - These can be single component or two component products and are very resistant to UV and have excellent gloss and colour retention. The main hazard associated with the use of polyurethane is the toxicity of the isocyanate component. Users must follow safety precautions and an air fed mask should be worn when this product is sprayed. Curing times are fast but pot life is usually around 4 hours.
Masking paper should always be applied with the 'shiny side out'. This is so the coating you are using will not soak into the paper, which could cause it to stick to, and damage the surface you are protecting.
