Rust-Oleum Mathys Murfill Waterproofing Coating
Rust-Oleum Mathys Murfill Waterproofing Coating is an elastic, crack bridging and waterproofing exterior wall coating with a microporous structure that ensures the substrate is constantly able to breathe. Ready for use on a range of surfaces, it is simple to apply on any exterior wall, this water based coating provides the highest protection and offers guaranteed waterproofing.
Rust-Oleum Mathys Murfill Waterproofing Coating can be applied directly on old (sound) paintwork after thorough brushing down. Chalking paints or new/unpainted substrates must be treated first with Rust-Oleum Mathys Primer 44 HS or with Mathys Pegafix, when the old paint coat (acrylic paint or Murfill Waterproofing Coating) is affected by the solvents of Rust-Oleum Mathys Primer 44 HS. On smooth non-porous substrates apply a coat of Rust-Oleum Mathys Pegalink Universal Adhesion Primer or a coat of Rust-Oleum Mathys Noxyde (except for white) diluted with 25% water.

Murfill, the Ultimate Reference in Waterproof Wall Paints for Over 30 years.
The Murfill waterproofing system has been the reference for coating and waterproofing façades for many years. Mathys introduced Murfill Waterproofing Coating in the early seventies. An elastic, durable and waterproof coating.
In test laboratories...
Diverse test reports by recognised laboratories confirm the exceptional product characteristics of Murfill.
..and in practice
Practice remains the best test. Murfill Waterproofing Coating has been used all over the world since 1975. And Murfill proves the same effectiveness in all climates and weather conditions. Hot or cold, dry or damp, rural, industrial or urban environment: it makes no difference.
A facade is the outer face of a building which is subjected to to many internal and external conditions like sun, wind and moisture. The possible causes of degradation are often hard to determine but can include: rising damp, moss, mould, algae and rusting structural reinforcements.
Durable protection and regular maintenance of your facades are of vital importance in preventing problems. Mathys therefore offers an extensive range of paints and coatings that will beautify and protect facades for years to come.
For more than four decades Mathys has been developing effective contemporary solutions for protecting, renovating and decorating facades. Mathys distinguishes itself through its expertise and unparalleled quality and has evolved worldwide into the first port of call for facade protection and decoration.

 Alistair Goligher on 2020-02-21 13:50:15 | Question:
Hi Which paint would be better for a pebble-dashed wall, Rust-Oleum Mathys Murfill or Zinsser Watertite ? Thank you Alistair |
Answer:
Rust-Oleum Mathys Murfill Waterproofing would be used in an external waterproofing application, Zinsser Watertite would be used internally only. | |
| Nathan Stroud on 2019-12-19 23:04:10 | Question:
Hi I want to use the rust olium murfil waterproof exterior paint on the side of my house but it's mid winter. How many clear day do I need? Do I need to apply on consecutive days and how much do I need for an 8m x 4m wall? Kind regards Nathan |

| teni begi loju on 2019-11-11 23:39:06 | Question:
Is this product effective in use for waterproofing pebble-dashed walls? If so, what colour would be best so as to minimise the colour change? |
Answer:
Rust-Oleum Mathys Murfill Waterproofing Coating is suitable for use over pebbledash walls, depending on the level of porosity Rust-Oleum Mathys Primer 44 HS may be required to prime the surface first. You can choose whichever colour you like from the range as this will not affect performance. | |
| Lauran on 2019-10-27 10:01:37 | Question:
Our home is externally painted with typical white paint (previous owners did this) What can we use to paint over/coat the exterior walls that are already painted that will waterproof the exterior walls? |
Answer:
Rust-Oleum Mathys Murfill Waterproofing Coating would be an excellent choice for this. | |
| Steven on 2019-09-29 10:08:17 | Question:
I have recently repainted my house. There is a slight water penetration in a small area in very rainy conditions. Can I use the product and repaint over with ordinary masonry paint? |
Answer:
Ideally Rust-Oleum Mathys Murfill Waterproofing Coating should be left as the final finish. Overcoating with other masonry paints can cause issues due how flexible Rust-Oleum Mathys Murfill Waterproofing Coating remains over time. | |
| ALEX FARMER on 2019-08-28 12:02:20 | Question:
Hi can Murfill waterproofing coating be used on timber as i'm looking to get the same colour on my timber cladding as i use on the house & If so do i need to pre-coat it with anything Regards Alex |
Answer:
This is not something we would normally recommend, but it could be done if you wished so long as it was timber, and not hard woods and not varnished or similar. We wouldn’t use anything else prior to Rust-Oleum Mathys Murfill Waterproofing Coating, but certainly would dilute the first coat quite a bit to ensure it “sinks in” to the wood. Preferably you would use a dedicated timber product for the wood areas such as Mathys Pegacryl Satin mixed to the same colour - yes there would likely be a slight colour variance but performance wise this would be much preferred. | |
| ALEX FARMER on 2019-08-15 14:11:09 | Question:
Hi what is the best preparation for painting unpainted facing block ?? Regards Alex |
Answer:
Rust-Oleum Mathys Murfill Waterproofing Coating can be applied directly on old (sound) paintwork after thorough brushing down. Chalking paints or new/unpainted substrates must be treated first with Rust-Oleum Mathys Primer 44 HS or with Mathys Pegafix, when the old paint coat (acrylic paint or Murfill Waterproofing Coating) is affected by the solvents of Rust-Oleum Mathys Primer 44 HS. On smooth non-porous substrates apply a coat of Rust-Oleum Mathys Pegalink Universal Adhesion Primer or a coat of Rust-Oleum Mathys Noxyde (except for white) diluted with 25% water. Cracks < 0.5mm wide: fill up with Murfill Waterproofing Coating. Cracks > 0.5mm wide: fill up with Rust-Oleum Mathys Elastofill or Mathys Mur-Filler. Active cracks must be bridged with Rust-Oleum Mathys Murfill Reinforcement Fleece. | |
| John on 2019-06-21 13:35:03 | Question:
I had Murfill Cream exterior "elastic" paint applied to my home 5 years ago and it still looks fresh apart from a gable end that gets direct weather. This gable is in need of a clean. What do recommend to clean it without affecting the integrity of the paint? Also, I had my window ledges painted in a reddish colour. Do you supply this? Thank you. |
Answer:
We'd need more information on what you require for your window ledges if you wish to contact our Technical Team on 0113 2455450 (option 2) or [email protected], but to clean the existing surfaces coated with Rust-Oleum Mathys Murfill Waterproofing Coating we'd recommend a 2% concentration of Rust-Oleum Mathys ND14 Cleaner Degreaser. | |
| Glyn Jones on 2019-06-19 10:15:31 | Question:

| terry.denning on 2019-02-18 10:35:13 | Question: Is this product suitable for painting over Santex cream paint as a protector for damp on exterior walls? will it help to keep out rain water. |
Answer: Rust-Oleum Mathys Murfill Waterproofing Coating is simple to apply on any exterior wall, this water based coating provides the highest protection and offers guaranteed waterproofing. It can be applied directly on old (sound) paintwork after thorough brushing down. Chalking paints or new/unpainted substrates must be treated first with Rust-Oleum Mathys Primer 44 HS or with Mathys Pegafix, when the old paint coat (acrylic paint or Murfill Waterproofing Coating) is affected by the solvents of Rust-Oleum Mathys Primer 44 HS.

| Ben griffiths on 2018-03-31 09:39:28 | Question: We have recently purchased a new property with stand alone building built in 1990's - it has external concrete render which has never been painted for some reason. The interior walls have faint traces of damp after this recent wet weather - what is best - simple masonary paint or something stronger and more waterproofing. The render still looks in good condition. |
Answer: We would always recommend a high performance product like Rust-Oleum Mathys Murfill Waterproofing Coating. Once clean and dry the bare concrete render should first be primed with Rust-Oleum Mathys Primer 44 HS before the application of Rust-Oleum Mathys Murfill Waterproofing Coating. | |
| John ashton on 2018-03-13 17:47:24 | Question: Hi I'm looking for a waterproof Paint or resin the building is already painted with a water based paint there is a lot of damp, so Im looking for a resin to put on then paint or a waterproof paint the colour is magnolia, the building is a old large Manor house could you help me please regards John |
Answer: Rust-Oleum Mathys Murfill Waterproofing Coating can be applied directly on old (sound) exterior wall paintwork after preparation. It is elastic, crack bridging and 100% waterproof but will still allow the wall to breathe outwards. | |
| Lydia on 2017-10-21 20:43:14 | Question: I want to use Murfill but before I buy 16kg of it, do you do sample pots of the colours? As it may look completely different colour on walls than it does on computer image. Also I have cracked matt painted pebble dashed type render that is probably 1920's (Old) what would be the best primer to use before this? Thanks |

| Richard Ward on 2017-06-11 17:53:27 | Question: I want to use Murfill on concrete as the previous paint has peeled off, what primer should I use, the site is exposed and near the coast.
Thank's |
Answer: New or unpainted porous substrates should be primed first with a coat of Rust-Oleum Mathys Primer 44 HS or Mathys Pegafix. | |
| Matt Stocker on 2016-09-17 18:42:40 | Question: I can't find the details of how long I need to allow for the paint to dry before it is waterproof and safe to be rained on. Just trying to plan around the weather! Data sheet only mentions handling time and recoat time, but no mention of waterproof time. If you'd be able to let me know, that would be great. |
Answer: When the full specified system has been applied (usually 1 x primer and 2 x Murfill Waterproofing Coating) and the final paint layer has dried sufficiently as per the Product Data Sheet (usually 24 hours at 20°C) then the system will be providing waterproof protection of the building. In good drying conditions (20°C/50% R.H.) then Murfill Waterproofing Coating should be 'rain proof' after 6 hours. Please note that fluctuations in weather/conditions/temperatures/etc. will affect these estimates greatly. | |
