Oil Based Exterior Paint Uk Masonry Paints
Is this newer type of paint the one to go for? Weathershield and it went flakey after a year or so. Preparation for exterior surfaces is not dissimilar to jobs indoors – surfaces need to be clean and dry, and woodwork lightly sanded or, in the case of ironwork, rubbed down with a stiff wire brush to key the surface.
Whites and creams blend in anywhere, and some historic towns have a prevalence of pink, blue, yellow or rust. It gives an authentic finish to older homes, but most importantly, it is a breathable finish that allows moisture to escape. Surface contamination such as grease and dirt could also be a problem. It is likely that the surface was contaminated. It’s also easy to apply and has all the quick drying and low odour benefits of emulsion paint. This is not unusual with standard matt emulsion paints especially when very dirty and stubborn stains are being removed. Any paint mixed by us cannot be returned. Hi there, would you like to get a quote? There are many ways to help improve the look of your property. As a general rule, masonry paint is used to paint the exterior of your property, whereas emulsion tends to be more for internal use.
If exposed externally, emulsion paint will not last. If you find the walls are wet or damp, this can result in a cold house or building. In worst cases, painting professionals will need to repair metal that is rusted, damaged or missing pieces due to climate conditions. So which is best and does it really matter? Afterwards simply coat with two or three coats of masonry paint in your chosen colour (the first coat slightly thinned with water).

Why has my internal woodwork painted with solvent based brilliant white gloss turned “yellow” over a period of time? General discolouration occurs with all solvent based paints over a period of time, but is particularly noticeable when brilliant white has been used.
Nicotine and oil burning appliances will also discolour the paint. Why has the gloss paint on the outside of my property dried flat? The loss of gloss on external paint coatings is usually due to exposure to damp or cold conditions while drying. Providing good ventilation is essential. Removing soft furnishings before painting is a good idea as the odour can cling to them. Apply the paint generously and spread it evenly, taking care not to overspread it. It would be ideal in this situation. When using this type of paint it is essential the surface to be painted is clean and dry. Failure to carryout any of these two simple processes will result in a lack of adhesion making the coatings much more susceptible to impact.
What has caused runs to appear on my gloss painted surfaces? This has been caused by uneven application or applying further paint where the coating has started to set creating thick joints.

Once the paint is sufficiently dry and hardened rub down and paint again. Generally the finishing coats need to be applied as soon as possible. The surfaces need to be washed down to remove as much surface contamination as possible. Leyland finishes can be applied over the product even solvent based gloss. Priming bare timber is essential for the success of the whole paint system. This provides a sound base for the next coating. The paint can be applied exactly as if emulsion paint was being used on a wall. The rougher or more textured the floor is the heavier the pile of roller needed. Why has the floor paint stuck to my car tyres? In most instances this is due to a lack of adhesion between the floor and paint coating. Applying a very thick coating in one application can also cause problems as the paint will take longer to cure. As a guide allow a drying period of a month for every inch of concrete laid in depth. Application of the paint to the floor before it is fully dry will result in a premature breakdown. Coverage is usually measured as a theoretical average of the paint being applied to both painted/unpainted and various masonry surfaces. Most surfaces paints are applied to are naturally absorbent. Unsealed surfaces will absorb more material which will reduce the spread rate. If they are clean and dry and in a sound condition a first coat of slightly thinned masonry paint would do. Not if the paint is going on to a sound clean surface but if there is a possibility the surface is extremely porous or chalky then a stabiliser is essential.
To ensure there is good adhesion of the masonry coating the surface must be non-glossy. Products should always be used in accordance with application instructions and precautions on the product data sheet. This is a water based material and if the paint film hasn’t had time to fully cure before the rain shower, the rain would soften & thin the coating causing it to wash away.
What would cause masonry paint to flake off? Moisture is a key factor too this may have been within the underlying substrate at the time of application or has entered during the period of exposure due to defects in the surface or leaking pipes and gutters etc.
Always check the surfaces carefully before painting. If intermixing cans is not practical try to find a natural break in the work. This product has been independently tested to give a life expectancy in excess of five years. I want to hide and disguise hairline cracks on my walls.

I need to paint car park walls and the clients specified an anti-carbonation coating can you help? These types of bricks are usually very smooth, un-absorbent and dense. Our technical team will be happy to provide further advice on any of the products featured here. We have a 1930’s semi and we are looking to paint the masonry windws sills and door lintels etc. I assume a traditional gloss paint has been used?
If the existing finish is indeed gloss then you can paint the upper sills with a coat of undercoat and a coat of gloss (rub down with sandpaper first).
The stone window sills on our 1930s semis have been painted & repainted over the years and want to re-paint – both houses at the same time.
We are preparing well and thoroughly but would be grateful for advice on the best masonry paint to use in the circumstances. There is no set paint to buy for all masonry. How long do you want the paint to last (life expectancy)? Has the surface been coated with anything before? What type of substrate are you looking to paint?
What is the surface/substrate condition?
Do you want elastomeric, micro-porous or anti-carbonation masonry paint? Do you want textured or smooth masonry paint? Which brand/system would you like to opt for? What is the difference between smooth and textured masonry paint? Despite what people think, a textured finish won’t give you any added benefit in harsh conditions. A textured coating can slow down moisture from flowing off the surface, opening up to damp problems down the line. Textured is more for decorative, creating a quartz or rough surface that is visually appealing. In urban environments, textured coatings can act as an anti-fly coating, preventing people from sticking posters and flyers to the building in question.
How to remove masonry paint from render, concrete, bricks? This can be tricky and messy, but there are ways around it. Get the right system for the substrate! Sandtex is a very good general masonry coating, however if you require a more bespoke solution to go onto a specialist or performance coating, we can offer that.
Murfill, for example, is the perfect system for coastal environments. Murfill can prevent salt from having a negative effect on the paint. Plus has an anti fungal additive for high humid areas to prevent mould and algae in these conditions. When talking about paint for urban environments we need a paint to protect against carbonisation. Masonry paint and emulsion are two very different things. Over time, small hairlines cracks can appear on the surface of exterior walls. An elastomeric paint is a paint that stretches, expands and contracts, moving with the natural ebb and flow of the building. It’s possible that you might, but this is dependent on the substrate. Is it lime render, brick or concrete render?
What system are you looking to buy or have you already bought? What conditions are you up against?
Answering these questions will be a good indication. It’s all dependent on the system and what you need the system to do. England has high humidity with over 80% a lot of the time and foggy too. Most masonry systems can be applied using brush, roller or spray, although some can only be applied by brush. When painting any interior/exterior wall, it’s worthwhile taking the time out of your day to check if the surface has been coated before. This depends on the surface area in question. We can talk to you about surface areas and application and work with you to determine how much paint you need to buy.
How much paint you need is also dependent on the substrate type and how porous the surface is. It also depends on what paint is being used as different paints have different coverage rates, so all things need to be considered. Choosing a product that will bridge the cracks effectively is essential. Elastomeric masonry protection is an ideal solution to meet your waterproofing requirements. These sorts of paints are highly effective for application to older buildings, where cavity wall insulation wasn’t included in the building regulations.
External walls that are exposed to the elements are far more likely to be effected and should be top of your priority list when looking to decorate and protect the outside of your property.
As well as specialising in breathable and elastomeric coatings, we can help you find an anti-carbonation coating to protect your exterior masonry from carbonation and water ingress.
For highly exposed conditions however, such as out on the coast or up in the highlands and islands, a high performance coating will usually be required.
