Would this product be suitable to paint onto the inside of Aluminium box gutter ? The box gutters are new aluminium that have been cleared together externally and my client wants an EDPM surface applied to the inside covering the joints ?

Assuming the aluminium is clean, dry, sound, lightly abraded and prepared as detailed in the technical datasheet, this product should be suitable for application to aluminium gutters to leave a waterproof membrane finish. When applying the self-adhesive EPDM, we'd recommend to test for compatibility and adhesion with this product prior to full application.

Would this product be suitable to waterproof the floor of my walk in shower? We have tiles and grout but the grout always comes out. Would this be suitable to paint over the top of the tiles and grout to waterproof it?

Unfortunately no this product is not suitable for this application, please can you provide more information on what the tiles are made of and pictures of the area in question to technical@rawlinspaints.com

Hello I am looking to use this product on marine ply to waterproof a boats deck would this product be suitable

No, this product wouldn't be suitable for this application due to the salts and chemicals found in the sea posing a risk.

Do you supply a paint that will water proof seal an existing epdm rubber roof.. the roof has started to leak a little in heavy rain after 2 years Thanks

Assuming the EPDM roof is bare, clean, dry, sound and you have prepared the substrate in accordance with the technical datasheet, this product is suitable for this application type.

Would this be able to be used on a gazebo polycarbonate roof that has been damaged by hailstones the holes made on penetrate the top skin in places. Is it available in any other colours

This product isn't suitable to stick to polycarbonate sheeting.

Hi, I want to paint a sloped wooden roof (gazebo) rather than felt. Would this be suitable? The wood is pressure treated so I know I'll have to dry it out first or is there a suitable primer that might help? Thanks!

Assuming the wood is clean and dry prior to application, this product will be suitable for this application.

can this paint be painted on cement corrugated roof sheet, is 1 coat sufficient?

Assuming you have a clean, dry and sound prepared substrate, this product will be fine to use for this application. One full coat should be applied in accordance with the application coverage.

Hi there can you advise if this is safe for fish ponds and if it will adhere to a butyl liner Thanks

This product is fine to use in ponds, however doesn't adhere to pond liner. We would advise to wait at least 48 hours after applying before refilling the pond, as this could harm any fish otherwise.

Hi I have a set of steps that run down the side of my property that have been previously coated with a GRP membrane. This has failed somewhere on the flight and has led to water getting into an adjacent structure ( masonry ) that abuts the steps. Looking for a product that can be paint or roller applied over the GRP and up the face on the adjacent wall ( GRP has been dressed up this also 150mm ) which is suitable for foot traffic and could possible be sanded also for additional non slip properties. Needs to look good also :-)

Unfortunately this product would not be suitable, please can you provide more information and pictures of the area in question to technical@rawlinspaints.com

hi i have metal steel container and the roof is leaking in places, would this product be suitable? many thanks

While this product can be applied to clean, dry, sound metal surfaces, it will not bridge cracks or gaps and should not be applied to rust. Assuming the area leaking has any rust removed, and gaps or holes are less than 2mm, it is clean, dry, sound and prepared as detailed in the technical data sheet you could consider Rust-Oleum Mathys Fillcoat Fibres .

To stop corrosion I want to paint the inside of a new cor-ten steel water feature reservoir, that will be filled with water.. Can I use this product ? iIf so what surface preparation is needed before using?.

For this application to a cor-ten steel water feature, assuming it is clean, dry, sound and prepared as detailed in the technical data sheet we can recommend two coats of Teamac Metaclor Underwater Primer followed by two coats of Teamac Chlorvar Chlorinated Rubber Paint . Blast cleaning to SA 2½ is recommended. If blast cleaning is impractical, mechanical cleaning should be employed but hand cleaning does not clean the steel to the required degree. This can be mixed to many RAL, NCS or BS colours in a gloss finish.

Would this product be suitable for applying over an existing exterior tiled terrace of porcelain tiles and then over tiling with new tiles .

While this product could be applied to the tiles unfortunately it is not suitable to be walked on or tiled over. Please can you provide more information and pictures of areas in question to technical@rawlinspaints.com and we can look for an alternative for you.

Can this be used on a flat felt roof especially if it is dry and otherwise sound?

Assuming the felt roof is clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Cromar Allweather Roofing Compound . This is an effective, general purpose roof coating that is resistant to water almost immediately after application, therefore ideally suited for winter use.

Hi can this be used on a metal shed roof On the inside to stop condensation. Thanks

No, for this application assuming the roof is clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Tikkurila Grafotherm .

Is this product suitable to waterproof the inside of a blockwork walled/concrete bottomed new build water feature that is circa 500mm high and 30 metres long. No fish just water feature.

Unfortunately no this product would not be suitable for this application to a blockwork walled water feature unless the area was rendered first. Assuming this is done, the area is clean, dry, sound and prepared as detailed in the technical data sheet it could be used.

can this product be used on on steel frame that will later be poured concrete on. and does it require a coat of primer on the steel before hand

Unfortunately no, this product is not suitable for this application. Please can you provide more information on the project to technical@rawlinspaints.com and we can look into a suitable alternative.

Can this be applied directly to osb3 boards on a small slightly sloping roof roof

Yes this can be applied directly to timber assuming it is clean, dry and sound.

Hi, Can this product be painted on top of a EPDN roof .

Yes this can be applied to a clean, dry, sound and prepared EPDM roof.

Can this be used to waterproof an external house wall made of brick and painted matt white. I plan to put 150mm of sub base against the wall above DPC , and worried about damp. Is this suitable please.its for a raised patio 6m long that buts up to my house

Unfortunately no, this product would not be suitable for this application.

Can this product be used on an old concrete path? The path is itself the ‘roof’ to a disused coal store cupboard below. The path is the main entrance to my property but has cracks and allowing water seepage into the store below.

Unfortunately this product would not be suitable for this application. if you would like us to assist please contact us by e-mailing details of the project to Technical@rawlinspaints.com.

I need to waterproof a wooden base for a marmoset enclosure, would this be suitable without fumes

This product is waterbased and low VOC, this can be applied to wooden floor areas that are bare, clean, dry, sound and prepared as detailed in the technical data sheet. Please note this has not been tested for any animal safe requirements.

I have built two raised vegetable bed out of concrete block and I want to render the outside, so i need to seal the inside faces to prevent water blowing the render. Is this product safe to use in a vegetable/produce bed? If not, can you recommend anything

Assuming the concrete blockwork is clean, dry, sound and prepared as detailed in the technical data sheet this can be used. While it does not state it is plant safe, it is waterbased and contains no solvents.

Need to seal a metal shed against a protruding wooden base. The base is covered with a plastic sheet. Rain seeps under the metal frame which extends by about 12mm onto the frame and there is no obvious gap between the frame and base. The frame protrudes a minimum of 60mm. thanks

Thank you for the enquiry, we will need more information to assist with this enquiry, please can you send pictures of the area and a description of what you are looking to do to technical@rawlinspaints.com

Hi Would this product be suitable to coat a galvanised steel drum? Also, is it harmful to fish? Thanks Michael

Assuming the drum is to be used as a fish tank no this would not be suitable. Assuming the galvanised drum is clean, dry, sound and prepared as detailed in the technical data sheet we can recommend the barrel is first prepared with Teamac Mordant Solution (T Wash) , Teamac Metaclor Antifouling Primer is applied followed by 2 coats of Teamac Chlorvar Chlorinated Rubber Paint for this application. This is available in many RAL, NCS or BS colours in a gloss finish. Once cured it will not be harmful to fish.

Can this be applied over an existing waterproof layer? (A painted-on layer, not sure what it is...)

Unfortunately no, this product is not suitable for overpainting an existing waterproofing layer. Assuming the previously painted roof is clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Cromar Hydrosil Silicone Roof Coating.

Can this be applied to damp wood?

Unfortunately no, the timber must be clean, dry, sound prior to application.

can this be applied over itself to build up thicker layer coating

It is recommended to apply this in multiple coats rather than one thick heavy coat to build up a thicker coating.

Can this be applied to the sides of a manhole made of brick that is partially filled with water when in use ?. The brickwork is solid but has started to crumble in a few places. I intend to empty and then let dry first. If this product is not suitable do you have any others. Thanks George

We would recommend using a chlorinated rubber for this application as it would be suitable for both above and below the water line. Acid etching would be recommended to prepare the surface, a diluted coat of Teamac Chlorvar Chlorinated Rubber would be applied before another undiluted coat.

What is the preparation concerning application to Metal

Thank you for the enquiry, we have contacted you directly for more information.

Dies it require a thinner if spraying?

This does not require a thinner and can be applied by brush, roller or hydraulic piston sprayer.

ColourPicker Explained

In general we sort colours for products into 2 main groups - ‘Ready Mixed’ and ‘Tinted’.
Tinted colours will always be more expensive than Ready Mixed colours as they need to be produced at the time of order using a tinting machine dispensing colourant into a base*.
During busy periods, this means that tinted colours could take longer, for example – a ready mixed colour ordered on a 3-5 day delivery might arrive within 3 days, however a tinted colour might take the full 5 days to arrive.

To find Ready Mixed colours, search "ready mixed" or select the Ready Mixed 'colour chart'. To see Tinted colours select a colour chart such as RAL, BS, NCS, etc. or search for a colour/hue to see available or related options.

To ensure fair pricing, we split colours into ‘Price Bands’ to group together similar priced colours. If you wish to search for the cheapest tinted colours, always select Price Band 1.

We make every effort to list all available colours, however we also offer a colour match service which can be accessed by contacting our Technical Team on 0113 245 5450 (option 2) or emailing [email protected]

*Colours are sold in the nearest tin size but actual paint volume per tin may vary up to 10% depending on colour

Colour reproduction of the Products on the Site is limited by the technology used to deliver web pages and by the colour representation of Customer’s own monitor and computer set-up. We have made every effort to display as accurately as possible the colours of our Products but we cannot guarantee that the colour shown on Customer’s monitor’s display will accurately reflect the colour of the Product on delivery. We recommend that Customer first purchases the smallest Product available or access an industry standard colour chart in person (and not digitally) to ensure that the colour is acceptable for its purposes.

Coverage

Varies with substrate conditions and application method/thickness. Typical coverage range:

15 – 20 sq. ft. / G (3.78L)

Application Tools

Rubber Coat is generally applied using a roller, paint brush or hydraulic piston sprayer.

Surface Preparation

Surface must be clean and dry, stable and free from spalling, efflorescence, dust, dirt, oils, surface flaking, poorly bonded or glossy paint, sealers, salts and other contaminates which may affect adhesion and product performance.

New concrete: must be allowed a minimum of 30 days cure time prior to application of Rubber Coat
New masonry surfaces: should be allowed to cure a minimum of 48 hours prior to application. Exterior surfaces should be power washed using at least 1500 psi to clear any surface contaminates.
For interior concrete surfaces: scrub with a TSP (trisodium phosphate).
For wood floor surfaces: Vacuum thoroughly and wipe clean.

Mixing

Contents generally do not need to be stirred prior to application.

Rubber Coat Application

Ambient temperatures should not be less than 5º C, and should not exceed 35º C during application and for a continuous period of at least 24 hours after application. Avoid hot, direct sunlight. Do not apply over coal tar, avoid solvents and solvent type adhesives.

Cure Time

At 25°C and 50% relative humidity, Rubber Coat fully cures in 24 – 48 hrs. Curing time increases with thickness, colder temperatures or higher humidity so environmental conditions must be considered before application.

Clean Up

Equipment can be cleaned with soap and water prior to cure of material. Baby oil helps remove cured product off hands.

Common Errors

Applying product too thick - May cause cracking and skinning over uncured product.

Inadequate surface preparation – May cause adhesion issues.

Applying over saturated materials – May cause blisters from water vapours.

More product can always be applied on itself. Better to do more coats to build thickness then 1 thick coat.

Tips

Wear disposable gloves to help with clean up.

Cover or leave brush in pail to avoid air curing the product if you want to use again.
