I wouldn’t recommend it for exterior timber for the reasons I mentioned above. I wouldn’t use it for any bigger blemishes on interior timber either. Simply because surrounding timber tends to draw water from powder fillers like these and swell up. You don’t notice at the time, but after you’ve sanded your filler and painted over, the timber shrinks but your filler doesn’t. This makes a bulge where the filler is. Ensure surfaces are dry clean and free from dust and loose materials. Remove all decayed wood down to Build up deep repairs in layers no more than 5mm. Allow each layer to dry thoroughly before applying next Yes, Tetrion All-Purpose filler can be used in a multitude of situations, but because they’ve tried to make a filler to do every single job, it desn’t do any job well. There are better products out there for every situation you’re going to come across. Yes, you will need a variety of products, but that’s just the way it is.

I used to use Tetrion all the time on interior projects. As mentioned above, it is nice and easy to work with and the results are stunning. The only issue is that 24-hour recoat time!! You just can’t paint over it on the same day and it is a real letdown. This is down to the filler (due to it also needing to stand up to the Great British weather) contains a small amount of cement. NOTE: Avoid using in wet or damp conditions. If rain or moisture is expected, cover repair with waterproof material I have switched over to Gyproc Easi-fill for interior walls and ceilings now. Easi-fil can only be used for this task really, but it outperforms Tetrion All-Purpose filler and it’s a whole lot cheaper.The issue I have when using Tetrion All-Purpose filler on exterior masonry work is the longevity of the product. It’s pants!! Say you fill a load of windowsills with it, the filler dries, then it rains. The filler just turns to mush again! A product which we are led to believe is capable of being used on the outside of a building turns to mush when it gets wet?? There is something not right with that. Regardless of whether you use Tetrion Filler, or go with a different product, you’re going to need tools to apply it. So, I thought I’d include a little section on what I use.
