Toupret Putty Mastic Review – Linseed Oil Putty

Updated May 27, 2024 | Posted Oct 12, 2020 | Product Reviews, Sundries | 5 comments

Putty Mastic is Toupret’s answer to linseed oil putty and fits into their range of fillers quite nicely. Like other linseed oil putties, you would normally use this product to glaze glass windows, or at the very least, repair around glazed glass.

You should do your glazing or repair 6 – 8 days before painting over, so the product has chance to skin over. Toupret Putty Mastic can be used interior or exterior and can be painted over using acrylic or oil-based paint.

It’s worth noting that like any other linseed putty, you can’t use this product in contact with bare timber, or the timber will absorb all the oil over time and the putty will crack. All you need to do is apply a primer to your timber, allow it to dry, then apply your putty. I hope you find my Toupret Putty Mastic review useful. Click here to see online prices.

 

Ease of Use Compared to Other Linseed oil Putties

 

Most linseed oil putties are an absolute pain to use. The oil seems to settle on top of the product in the tin and you get covered in the stuff when you pick some up. You also have to work it in your hands before applying just to worm it up, then pick any hard bits out. It can also be sticky and hard to get it off your hands which is annoying, especially if you’re up a ladder.

I can honestly say Toupret Putty Mastic is a completely different animal. You get no separation between oil and product, it won’t stick to your hands and it is nice and smooth to use. I have tried many similar products over the years and believe me when I say this one is by far the easiest to use and even a novice could get amazing results with minimal swearing.

The other advantage of using this putty is it’s shelf life. I have stored half used tins in my van for well over 8 months and it’s still been good when I did come to use it.

 

The Overall Effect

 

Brilliant. You can sculpt Toupret Putty Mastic so easily that as long as you use the right tools, you’ll have no problem making your glazing job look very neat. It’s just such a smooth finish with no sagging at all. It’s a big step up from any other linseed product on the market.

 

How Much is it and Where to Buy

 

Erm, Toupret Putty Mastic is very expensive at around £15 per litre. That puts it at three times the cost of any other linseed oil putty. You get what you pay for though, a premium product at a premium price. I get mine online, or from Dulux Decorating Centre. Click here to see online prices.

Final Thoughts

 

Touptet Putty Mastic is quite simply the best linseed oil putty on the market, and I’ve been through the lot. That said, technology is changing, and there are now alternatives. Oxera Multi-Purpose Glazing Sealant is a polymer-based product which out-performs traditional linseed oil products at every turn.

You can paint over it after an hour, it lasts longer than linseed oil putty, creates a better seal and adheres to basically everything. It is a little bit messy, so take care on application, but I genuinely believe the industry is now turning away from linseed products.

    Hi thank you for your review. I bought Toutpret putty to reglaze old wooden sash windows. I painted the wood surface and let it dry before applying the putty. I am no expert but this stuf was really easy to work with and pretty satisfied at this point. My problem is: 45 days on, the putty is still flexible, I can put my finger tips in it will leave a mark. I was really expecting it to go rock solid and ready to get painted after 10 days so not too sure what to do at this point. Any idea of what could have gone wrong?

      Thank you for your comment. Nothing is wrong, don’t worry. It takes months for any putty to harden up. You just need it to skin over before you paint it, and yours will be.

      Hope that helps

    Hi,

    I’d like to ask if this product can be used as a seal between limestone and UPVC window frames?

    With thanks…

    HI tx for the review, very helpfull. I was considering using this as I’ve used other toupret products and they are very good. I am concerned though that you say need acrylic or oil based paint. I’ve been using ronseal water based range, the superflexible primer/undercoat and their 10 year gloss. I find them easy to use and still quite durable so far? what do you think of this product?.

    Would that be ok to use or should I use something else for the putty part?

    thanks david.
