Soudal Fixall – High Tack

Soudal Fix All High Tack is a single-component MS Polymer adhesive and joint sealant built for situations where you need the thing to stay put while you get on with the next job. The high initial tack means less propping, less waiting, and less cursing at materials that slide before they cure. If you’ve ever stuck something to a wall and watched it slowly migrate downward, you’ll appreciate why that matters.

Based on Soudal’s MS-Polymer technology, Fix All High Tack cures quickly, building end strength fast without any primer on most common building substrates. It contains no isocyanates, no silicones, and no solvents, so there’s no harsh smell to deal with and no compatibility headaches with paintwork. Once it’s cured, the bond remains elastic, which matters on anything subject to movement, vibration, or thermal expansion.

What Makes Soudal Fix All High Tack Different

A lot of grab adhesives are fine until conditions get awkward. Fix All High Tack bonds to wet substrates, which is genuinely useful on site where you’re rarely working in ideal conditions. It’s paintable with water-based paints once cured, has good UV and colour stability, and resists mould growth, making it a practical choice for kitchens and bathrooms as well as structural work.

Colour Options

Available in white, grey, brown, black, and clear, so you can match the finish to the application rather than just hoping nobody looks too closely. For exposed joints in particular, colour matching saves a lot of touching up later.

Soudal Fix All High Tack suits joint widths from 2mm up to 30mm and can be applied anywhere between 5°C and 35°C. It works with a standard manual or pneumatic caulking gun, and the formulation tools and finishes cleanly without too much fuss.
