Unika ColorSealant CS4222-AZ Acrylic Gap Filler and Sealant, Medium Oak, 0.57 kg

Whoa! Well, they delivered my nice oak skirting to match my new oak floor and it looked great. The chap came to fit the skirting and this is where the fun began. The skirting was pretty much ‘true’ in its size and shape but sadly some of the walls and the floor ! were not. So, I hurriedly sent for a nice tube of this seal from Amazon and chose the medium oak which was just about perfect to match my floor and skirting. Please see the attached photos as I used it in three main ways. First up: there was a bit of an untidy line where the floor met the frame of the door. The floorer had used a bit of masking tape then used some really old and crumbly seal but forgot to remove the tape. My wife and I then spent an age trying to remove and unpick the dreadful tape he’d used and the seal looked really ragged. I asked the joiner who fitted the skirting if he would re-do this with the new seal and it looks much neater. Please note, it’s such a long length – about 3m - that I’m not sure I could have done this with my meagre skills. Second up: the joiner cut slots where the pipes fed the radiator. He left these grooves as they were but I wondered if I could maybe cut a little bit from the offcuts of skirting to slot down the grooves and on to the top of the radiator pipes. This actually worked quite well (for me!) but the dilemma I then has was how to secure the pieces in the right place as they weren’t really tight enough for me to use glue. I found that a nice squodge of the seal either side of the fillet of wood and then a careful positioning both retained the pieces and also filled any gaps ( ie the great chasm between the slot and my cutting! ) Thirdly: the skirting was not quite flat to the floor and there were gaps below. From a distance these were quite evident. I therefore used an oak filler carefully and painstakingly swept into the gap using wooden lollipop sticks and an old credit card. This took forever, killed my knees and my back but looked okay – ish. I found late in the day that using this seal was much easier. It was easier to get into the gaps using a trigger gun and for the tiny gaps I used 5mls syringes bought from Amazon that I filled with the seal and then slowly squirted into the small gaps. I used masking tape to make sure I didn’t get too much on the wall and also it protected the skirting – so that good results were obtained quickly. The small gaps just seemed to disappear. The gap I was most terrified of, however, was one where the wall bends away just a little from the skirting, opening up a gap of about 8mm. I was not sure that the seal would cover this gap. I therefore applied my masking tape above the line on the wall where I wanted the seal to finish i.e. level with the top of the skirting and also another piece of tape on top of the skirting. I used the gun and squirted the seal in. I left it for a minute or so and then smoothed it down with my finger (you’ll need lots of disposable gloves). Any gaps that appeared, I re-filled two or three times until I had filled the whole gap. This worked much better than I thought and most crucially and a bit of a novelty for me – it looks really good! One or two further points if I may? The seal is quite pleasant to use. It does not have that horrible all-pervading vinegary smell that acrylics have. As one reviewer points out its more caulk than acrylic. Colour match is good – I used medium oak. Clean up is easy. Okay, for me it went everywhere and I went through loads of gloves but the nice thing is that you can wash it off and also use a damp cloth on the walls and skirting if some of it has got away from you. It dries overnight and of course you can paint it – you may be able to see on the photo with the large filled gap- the masking tape brought some paint off -so it will need retouching. All in all, I am very pleased with my efforts and also this seal which is quite easy for a hopeless DIY man like me to at least make an attempt to refine and tidy when the professional trades had left gaps and missing pieces. I’m not sure how robust it will be as regards wear and tear but I reckon that’s for another day. If it really starts to fall apart, I will report back but for now it looks – a new word for me – finished! Happy skirting-sealing and filling. Photos as per text.

Filled a massive unexpected gap in my laminate flooring when under the stairs storage fitted. Avoided having an aesthetically poor cover strip and looks great! Great colour match. Dried quick enough but not too quick that I (with no skills) could attempt the smooth finish more than once! Easily removed the excess from the new storage with a fresh plastic scraper - no scratches no remnants.

I've used a lot of mastics, sealants, caulks, fillers, etc over the years and often find the coloured ones are a disappointment. This one was exactly what I was looking for. The colour is good and doesnt look like toffee as so many do. In some areas I left the product as-is, in others I stained or painted. In all situations it looked blended into its surroundings well. Application was good too and it left a nice smooth finish. I'd definitely use this product again and would consider alternative colours too.

Pricey but worked a treat on my repair job

Good quality caulk, easy to use and clean up

great match , doest the job that its required to do so

This was easy to use but the colour was darker than expected when dry.

It’s an acrylic sealant so it cures differently from a silicone sealant. I mean- don’t get it wet whilst it cures!! Other than that it’s exactly as advertised.
