Time had taken its toll, and along with the looks and tuts from the painter, the cost, whilst reasonable, was still quite pricey. Long story short I decided to do some of the preparatory work myself. I needed stuff... and along with an electric sander (purchased elsewhere), I bought palette knives and this wood filler. If you are reading this, you will already know there is a multitude of options out there when it comes to fillers. I chose this one for several reasons, but in part it was because Ronseal describe it as 'High Performance'. I'm a sucker for 'Heavy Duty', 'Professional', or 'High Performance' products. Once I had prepared the area, and replaced any small bits of wood, I mixed the first batch. Yes I did say mixed... I was hoping it would be ready mixed but that was not to be. The instructions say a golf ball of filler to a pea of hardener. This was pretty straight forward, and it mixed well. Be aware however that there is a strong chemical smell. I personally don't mind it, but it will fill your house for an hour or two if mixed indoors. The problem with mixing filler, where the instructions are 'visual'... is it is easy to get it wrong. I do not know if the proportions I used were perfect, it seemed ok to me... but what I do know is the filler started to harden within minutes. It was still workable for the amount I had prepared, but be aware. The filler was fully hardened within half an hour or so, and was capable of being sanded, which I did. The colour was a nice bright white, which was perfect for painting with the same colour. I was very pleased with the results, it sanded to a nice smooth finish. I didn't need to nail or screw into it, so can't comment on that aspect. I only used about two thirds of the can, but am confident that the remains will last for a while due to the fact it is not ready mixed. The number of rock hard tubes of filler I have thrown away would have paid for the painting, and bought me a drink to admire the job. All in all I like this product, and would definitely buy it again. Five Stars. Review: Excellent - Worked well on external wood surface. You have to mix with the hardener supplied and use quickly before it dries. But sticks to surface well and easy to layer up. Dried well and withstood a lot of heavy rain before being able to paint over it ## Features - Causes damage to organs through prolonged or repeated exposure. - Causes serious eye irritation. - Causes skin irritation. - Flammable liquid and vapour. - Harmful if inhaled. - Suspected of damaging fertility or the unborn child. - Can be drilled, screwed or planed - Rebuilds rotten wood - Cures wet rot and prevents recurrence - No shrinking or cracking - For interior and exterior use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001GU6IW2 | | Best Sellers Rank | 13,998 in DIY & Tools ( See Top 100 in DIY & Tools ) 94 in Wood Fill 1,824 in Hand Tools (DIY & Tools) | | Brand | Ronseal | | Colour | White | | Compatible Material | Wood | | Container Type | Bottle | | Customer Reviews | 4.5 out of 5 stars 539 Reviews | | Full Cure Time | 3E+1 Minutes | | Global Trade Identification Number | 05010214825769 | | Included Components | Ronseal High Performance Wood Filler - White 550g | | Item Form | Paste, Putty | | Item Package Quantity | 1 | | Item Type Name | Ronseal High Performance Wood Filler - White 550g | | Item Volume | 19.4 Fluid Ounces | | Item form | Paste, Putty | | Manufacturer | Ronseal | | Manufacturer Part Number | 35305 | | Material | Wood (compatible material) | | Model Number | 35305 | | Number of Pieces | 1 | | Other Special Features of the Product | Crack Resistant | | Special feature | Crack Resistant | | Specific Uses For Product | Interior wood repairs, Exterior wood repairs, Window frames, Sills, Doors, Door frames | | Specific uses for product | Interior wood repairs, Exterior wood repairs, Window frames, Sills, Doors, Door frames | | Unit Count | 550.0 gram | | Viscosity Level | Medium to High | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Ronseal - **Item form:** Paste, Putty - **Material:** Wood (compatible material) - **Special feature:** Crack Resistant - **Specific uses for product:** Interior wood repairs, Exterior wood repairs, Window frames, Sills, Doors, Door frames ## Images ![High Performance Wood Filler - White 550g - Image 1](https://m.media-amazon.com/images/I/61JclguejRL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great filler, but don't hand about. *by L***T on 6 August 2026* The time had come that every home owner dreads... the outside needed painting !!
