A popular question asked by many diy enthusiasts, which decorating filler is best? During my time as a painter and decorator I have tested many interior and exterior fillers. Today I am going to discuss one filler that I and most professional decorators use on a daily basis.

Best Interior Decorating Filler

Although there is a wide range of interior fillers designed to repair cracks and holes in plastered walls and ceilings. Most unfortunately in my opinion are inadequate at best. Why you might ask, well, when looking for a really good interior filler there are a few properties that are essential.

1) The powdered filler must mix easily with minimum effort, ensuring a smooth consisting, (no lumps). 2) Workability, the filler must be easy to spread and have a long enough working time that the amount mixed can be used up before starting to dry out. 3) Drying time, the filler must dry fast once applied to the surface  4) The final point is absolutely essential, the filler must be easy to sand without having to use an orbital sander to get the job done.

So which decorating filler is best and meets all of the criteria above. The answer, Toupret Interior Filler is hands down the best decorators filler on the market. I have been using the filler for years and highly recommend it, due to the nature of my profession, I purchase in bulk, 5kg bags.

How Do You Mix Filler For Walls?

When it comes to actually mixing your filler whether its for interior or exterior surfaces. There is a simple, fast, mess free way of mixing filler. Before you start there are a few items below that will come in very handy, let me explain why.

1) Toupret Interior Filler
2) Flexible Mixing Bowl
3) Flex Filling Knife 1 inch

Toupret interior filler comes in both a powdered and ready mixed format. Toupret Interior Filler (powder) comes in a 2kg box, 5kg bag and 10kg bag, while the Toupret Ready Mixed Filler comes in a 330 gram tube or 1.5 kg tub. The only downside of the ready mixed version, is that drying times are double that of the powdered version.

Mixing the powder filler is really easy, using a flexible mixing bowl pour some filler into the bowl. Add a little water to the powder and using your 1 Inch Flex Knife mix the filler until you achieve a smooth consistency.

The ideal consistency is smooth, creamy with medium firmness. The filler should stick to your flex knife when turned upside down.

How To Use A Powdered Filler

Once you have mixed your filler to the correct consistency. The next step is to apply the filler to your walls and ceiling, filling any (cracks, voids, gouges, holes). The easiest method that I have found is to use two flex knifes, Purdy Flex Filling Knife 3 inch and a Purdy Flex Filling Knife 6 inch.

I use the larger knife to hold the mixed filler and the smaller 3 inch flex knife to work with. Always squeeze the filler into the crevice or hole ensuring the area is completely filled. Then wipe of any access with your flex knife, deep cracks and holes will need a second fill as it’s very difficult to successfully fill large holes and cracks in one pass.

At times when skimming over larger areas, switch or plug sockets for example. I will use the large 6 inch flex knife as the larger blade stays in contact with outer surface of the wall surrounding the hole, when removing excess filler.

Please note: there are limitations to filling large, deep holes with Toupret Interior Filler. Although the data sheet indicates that there are no limitations to the depth that can be filled. Realistically if your attempting to fill a large void left by a double plug socket that has now been removed.

It would be unrealistic and a waste of filler to attempt to fill a hole of this size and depth. Instead, use any of the two products below to fill 95% of the hole.

1) Ronseal Smooth Finish Big Hole filler
2) Cementone General Purpose Mortar Grey

Ensure that the masonry repair filler remains 3-5 mm shy from the surface. Once dry, skim the remaining 3 -5 mm with Toupret Interior Filler.

Toupret Filler Review

If you type the phrase “which decorating filler is best” into google, you’ll be amazed by the number of results 61,300,000 to be precise. I hope that I have clarified the question, most professional decorators swear by Toupret products and for good reason.

Their interior filler has many benefits which make it the choice of many professional tradesmen. Below are some additional benefits that you may not be aware off.

1) Toupret interior filler doesn’t flash and doesn’t need primed before painting. Flashing is when light reflects against a freshly painted surface to create a shimmering “flashing” effect. This can happen when using an inferior filler, unless primed before painting, the patch of filler will show through once the paint is dry.

Unlike other fillers, you can paint directly over toupret filler without having to prime the fresh patch or patches of filler.

2) Shrinkage, this can also be a common problem with other fillers. As the filler dries, it shrinks meaning that even small holes, cracks will need filled for a second time before painting. Toupret interior filler will not shrink or slump when drying.

3) Toupret interior filler is referred to as a one coat fill. What does this mean, in most cases, cracks, scrapes, gouges and holes can be filled with one coat.
