Exterior Surfaces
Can I apply exterior filler onto damp walls?

MASONRY REPAIR FILLER is very good for deep masonry repairs, can be shaped, and can be applied to damp masonry. You can use it to fill big defects in the substrate and you can also skim with it. It's paintable after 48 to 72 hours.

Can I skim with exterior filler?

Yes! Our EXTERIOR SKIMCOAT FILLER comes in powder or ready mixed version. It is designed for smoothing old or damaged render and can also be used to skim over masonry locally.

Rock Solid Repair Filler vs. Masonry Repair Filler: Which should I use?

For bare masonry, damp or dry, apply Masonry Repair Filler. For all other dry substrates, including glass and glazed tiles, use Rock Solid Repair Filler.
Due to the strong properties of Rock Solid Repair Filler, it will need to be shaped and sanded before it sets. Masonry Repair Filler, on the other hand, can be sanded with ease.
If you’re looking to paint over the filler, consider that Masonry Repair Filler is cement-based and therefore requires pH levels to drop back before you are able to do so.
This will take between 48 and 72 hours. Rock Solid Repair Filler can be painted over in 24 hours, regardless of the depth to which it has been applied. 

Interior Surfaces
Can INTERIOR FILLER be used on wood as well?

INTERIOR FILLER isn’t suitable for wood but WOOD REPAIR FILLER will be perfect. You will be able to paint or stain it in 3 hours.

When skimming, my filler sagged, didn’t cover well and didn’t dry as quickly as it should. What’s going wrong?

When using powder fillers, make sure you are using the correct mixing rate of water to powder. If you use too much water the filler will be ‘loose’. The mixing rate is stated on the packaging. For a smooth mix, don’t forget to add the powder to the water. Not the other way round!

Do you have a skim filler that can be applied with a roller?

Yes, all of our skimming products can be applied with a roller assuming you will smooth over with a trowel or knife afterwards. This is important because some fillers may crack if the coating is too deep.

Joint Skill and Fill
What’s the difference between JOINT, SKIM & FILL: QUICK DRY and PATCH & REPAIR FILLER: QUICK DRY?

There are a couple of important differences between these products, which are designed to complement each other. JOINT SKIM & FILL is designed for doing large areas of jointing and skimming, PATCH & REPAIR for smaller holes and cracks. First, the adhesion on JOINT, SKIM & FILL powder conforms to European Standard EN 13963 which concerns reaction to fire and flexural strength for jointing products. For this reason, we proudly bear the CE logo on the jointing products in the range. This is the standard that’s required for commercial jointing, so you can be sure the product will stand up to the job. Secondly, PATCH & REPAIR powder is a bit harder than JOINT SKIM & FILL  powder when dry. Because JOINT SKIM & FILL is primarily designed for smoothing over larger surface areas, the formula helps to make the job of sanding over large areas easier and more comfortable! But sanding is still easy when using PATCH & REPAIR to fill smaller holes and cracks.

What is the difference between JOINT & SKIM READY TO USE and RENOVATION SKIMCOAT?

The JOINT & SKIM product is very fine and is designed mainly for taping and jointing and fine skimming on plasterboard. The RENOVATION SKIMCOAT is especially good for levelling surfaces and thicker applications, such as covering textures (but can also happily be used for taping and jointing).

Can Joint, Skim and Fill skim over Artex® and have a long-lasting, hard finish?

Our Joint, Skim and Fill ready mixed and powder products will both do the job depending on the depth of the Artex. If it’s been de-nibbed, either would be fine and will be just as hard as plaster, dry wall and other fillers.

Preparation of the substrate
Which TOUPRET filler to use for leveling the surface of an exterior wall made of various materials and locally covered with paint?

First of all, you have to make sure that the paint on the substrate is not a waterproof soft coating. This kind of coating cannot be covered by any filler and requires to be stripped beforehand. If not, after scratching non-cohesive areas and checking the moisture rate of your substrate, you can apply Murex or Fibarex to fill holes, cracks and various gaps. Once your local filling works are dry, and in order to enable you achieve a satisfactory evenness of the wall, you can apply Fibarex or Planirex into an overall coat, up to 5mm. Once these operations have been carried out and once the filler overcoats are dry, then you can apply the finishing coat.

Can I buy direct from Toupret?

Unfortunately, we don’t sell direct, but you can find your nearest distributer on the Find a Distributer page of our website. Or if you’d like to Contact Us we can ask your local Toupret sales/technical representative to get in touch.

Does Toupret have any stockists in Ireland?

We distribute via Relay global in Ireland. You can find stockists on their website.

When you say no need to spot prime and will not flash, is that for all paints regardless of sheen level?

Yes. Any paint is fine. Just make sure the filler is completely dry before you start painting.

Do your fillers still allow the walls to breathe if a large area is covered?

Yes, they do. Our fillers are moisture vapour-permeable so your wall will be able to breathe, even if a large area is covered.

Can I mix powder filler with paint?

For best results, we do not recommend mixing our fillers with any other additives. 

Are Toupret products suitable for use on lime render?

Yes, all our products are suitable for use on lime render, and we advise undercoating before filling. For individual application specifications, refer to the product technical data sheet.

Problem Surfaces
Which filler would you recommend to treat damp walls?

ANTI-DAMP RENDER is treatment filler dedicated to interior of exterior damp masonry. It applies on raw substrates, either into light coats by brush or into thick coats with a trowel or a blade. It enables to level the irregularities. It applies into a crisscross pattern. Whatever the application tools (brush or trowel or blade) a coat thickness of minimum 2 mm is required. ANTI-DAMP RENDER only applies on raw and non-dripping substrates [refer to the technical datasheet]. It will stand as a barrier against the residual water contained in your substrate while enabling the water vapour evaporation thanks to its high water vapour permeability. This is the reason why it is absolutely necessary to ensure that the over coating paint should be water vapour permeable too.

What is the maximum depth for Anti-Damp Render?

Anti-Damp Render is best applied to damp substrates to a depth of up to 1cm. Any deeper, and the breathable barrier created by the filler may be compromised, blocking the water flow to such an extent that it may force its way through the filler, causing it to peel off.
