One of the complaints levelled at all paint manufacturers concerns moisture blistering, which is probably one of the hardest problems to explain to the repairer on the bodyshop floor. With inclement weather conditions, there are bound to be some cars developing moisture blistering which is more often than not blamed on the paints used. The bodyshop rarely realises that the blistering is due either to application, conditions in which the vehicle is sprayed, preparation, or indeed the weather itself.
The cause of blistering is saturation of the film by exceptional levels of atmospheric humidity, together with the presence of water-soluble materials, either absorbed into the film or present on the surface before painting. The blisters are formed when the moisture eventually escapes from the film as humidity decreases and temperature increases. The pressures formed in the film are enormous and often sufficient to deform the film into blisters. Where very low temperatures are involved, moisture freezes in the film and this leads to weakness in adhesion, which make the subsequent blistering much more likely.
One of the main causes of this phenomenon is osmotic pressure developed by the meeting under and in between the different layers microblistering. It may be that contamination is caused by moisture or even road salt. If a vehicle has been subjected to road salt and this is not very thoroughly flatted out of the film, osmotic blistering will occur when it is repainted.

General
Users are advised that the actual paint colour from the container might not be identical to that shown on shade cards, brochures or in photographs. The differences can be caused by a number of factors that will result in colour variation, these include different substrates, different level of gloss which will affect the perceived colour, different angle of viewing, the level and type (fluorescent, tungsten, natural daylight etc.) of lighting.
Uniform Colour
A major problem is that people start painting an area and run out of paint, buy more and then notice that the two colours are not exactly the same. This sheet gives some advice and steps to take to avoid this happening. It also includes some information as to why different containers of what is the 'same' colour might look different when applied.
How Much Paint?
To minimise problems of having too little or too much paint it is important to calculate as best you can how much paint you will need.
In-Store Tinted Paint and Ready Mixed Paints
Do not use both ready mixed paints (those already in the container with specified colour) with in-store tinted paints (paints prepared in store using base and tinters). This is because there is always a tolerance in producing any colour and it is likely that when produced in a manufacturing plant it will differ to that made up in a store.

CE Marking
As part of the requirement of the Construction Products Regulation (CPR) (305/2011EC) products that comply with this regulation have to carry the CE mark either on the product and/or on the attached information that accompanies the product. To meet the requirements of the CPR the product has to conform to a ‘harmonised standard’ (hENs)*.
The CPR also requires that products that are in scope have a Declaration of Performance (DoP) that goes with the product, this will give information on the hEN that the product complies with.
Paints
Many companies have been asked why are their paints which are used in/on construction products are not CE marked. The simple answer is that there is no harmonised standard that the paint can be tested against to see if it meets any specific requirements. Without a standard it CANNOT be CE marked.
Standards
The European Commission issues Mandates which lay out ‘essential requirements’ that a product has to meet to comply with the Construction Products Regulation.

We have no experience of this but we wouldn't recommend it.
I would assume from the description that this is a metal substrate? If so our initial suggestion would be Rust-Oleum Mathys Noxyde. If you contact our Technical Team on 0113 2455450 (option 2) or [email protected] with some further information - size, images, etc. then they would be able to provide a more detailed specification for your project.
We would recommend applying Thermilate InsOpaint Anti-Condensation Paint. Thoroughly clean down the surface, lightly sand to remove the sheen on the existing paint and apply 2 - 3 coats. This can then be left as a finish or over painted with your own paint/colour if required.

Could you advise which product you require this colour in please?
Yes you can see our range of aerosols HERE.
This information relates to Sikagard 206 W (Sterimatt) in BS 14C31. Sikagard 206 W (Sterimatt) has been discontinued by the manufacturer and has been replaced with Sikagard 406 W which is also available in BS 14C31.

You haven't advised which specific product you are using or intend to use but usually not, the topcoat would be required to be applied in quick succession to ensure weather resistance.
See our blog post How to Prepare and Apply Epoxy Floor Paint to Your Old Concrete Garage Floor.
We would suggest 503 Easy Clean Anti Slip Coating - ensure that the self levelling product used is OK to be left as a wearing surface and receive an epoxy coating.

MMA stands for Methyl Methacrylate, and it is typically used in heavy duty interior and exterior floor products - for high traffic areas on suitably primed concrete, bitumen, tarmac and asphalt.
Methyl Methacrylate
As a reactive resin, MMA's polymerised form can be found in a range of products at Rawlins Paints and wider afield, including:
- • Floor coatings
- • Flexible floor coatings

There are vast types of paints available for all sorts of specialist projects. We have tried to simplify your search on our website with comprehensive categories and sub-categories.
If there is a specific paint or use you are looking for, you can also use the ‘Search’ tool which will prompt/suggest products you may be looking for.
Each header has a dropdown box, and then each category has further subcategories that appear to the right when the cursor is hovered over the category name.
We have a designated ‘Wood Finishes’ category under ‘Paints & Coatings that categorises further into:
- • Wood preparation
- • Interior wood finishes
- • Exterior wood finishes
- • Wood floor finishes
- • Decking paint
We stock a comprehensive range of wood varnishes, stains, oils, protective finishes, and wood paint for both interior and exterior uses – pretty much every project you can think of is covered by a product in our range. Whatever you need, we can provide advice on the best wood finish to use, from heavy duty floor varnish to opaque wood paint, decking oil to Danish oil, and water-based or solvent-based.
A primer is a preparatory product. It creates an extra layer between your paint and the substrate, helping it last longer, bond better and often smoothing out the surface for optimum lifespan and performance. To look at it a different way, makeup primers are used for the same purpose in cosmetics!
Primers can also be used to add more specific extra protection, such as using a UV primer, a waterproofing primer or a penetrating primer.

We would suggest Blackfriar Anti-Slip Deck Coating here, test a small area first to ensure compatability, appearance, adhesion etc. before doing the whole area.

Assuming this is standard universal beams and columns in a domestic residential property with steels located in interior, dry environments needing 30 minute protection we would recommend Zeroflame Aquasteel WB+ 30min System for Steel.
We would need to know the composition of the headboard so that we can match it as closely as we can to a test?
Unfortunately we don't have any fire retardant paint for ceiling tiles.
