Assuming the wall and the previously applied coating is clean, dry, sound and prepared as detailed in the technical data sheet it can be applied.

If there are any bare areas of render this should be primed prior to application with Primer 44HS.

Yes a primer will be required.

On bare porous substrates you will need to prime with Rust-Oleum Mathys Primer 44 HS or Mathys Pegafix.

If the bricks are non porous you will require Rust-Oleum Mathys Pegalink Universal Adhesion Primer.

These will not effect the breathability of the paint.

For application to a bare block work wall assuming it is porous, clean, dry, sound and prepared as detailed in the Technical Data Sheet we would recommend priming with Rust-Oleum Mathys Primer 44 HS or Mathys Pegafix.

For previously painted surfaces Mathys Pegafix is recommend as solvents in Rust-Oleum Mathys Primer 44 HS can effect existing paint.

Assuming the stone window ledge is clean, dry, and sound, then yes it can be used on the window ledge with the correct primer applied first.

If the stone is porous prime first with Mathys Pegafix.

If the stone is not porous priming with Rust-Oleum Mathys Pegalink Universal Adhesion Primer would be required.

This paint is design for masonry, assuming the timber fence is clean, dry and sound we can recommend Zanders PF59 Stain Blocking Primer Finish on bare timber followed by Wethertex OT25 Wood-Flex Satin Opaque Timber Paint.

Yes, to ensure homogeneity, coating materials should be thoroughly stirred prior to use.

Rust-Oleum Mathys Murfill Waterproofing would be used in an external waterproofing application, Zinsser Watertite would be used internally only.

Application of a water based product like this would not be possible at this time of year. The minimum application temperature for Rust-Oleum Mathys Murfill Waterproofing Coating is 5°C and maximum 80% R.H.

Drying Times At 20°C/RH 50%

• Touch dry: 45 minutes
  
• Dry to handle: ± 8 hours
  
• Dry to recoat: 24 hours
  
• Fully cured: ± 2 days

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.

Rust-Oleum Mathys Murfill Waterproofing Coating would be an excellent choice for this.

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.

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.

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.

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.

Yes, this would be 'BS08B15' on the colour picker for this product.

Yes there is a brochure which has some applied samples of the various versions of the product if you would like to provide an address we can post to.

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. 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.

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.

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.

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.

Cracks

• Cracks < 0.5mm wide: fill up with Rust-Oleum Mathys 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.

Samples are not available for this product but we can send out a RAL chart upon request.

No.

New or unpainted porous substrates should be primed first with a coat of Rust-Oleum Mathys Primer 44 HS or Mathys Pegafix.

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.
