HOW TO USE
PREPARATION
1. Joint surfaces must be sound, clean and free from contaminants such as dust, oil, grease and any loose material. Very porous surfaces must be primed using a diluted PVA.
2. When the product is used to fill gaps, the temporary use of masking tape to define edges of the joint will often give a cleaner, neater look. Always remove masking tape before the filler skins, which usually takes between 15 to 60 minutes, but is dependent upon drying conditions.
APPLICATION
3. Unscrew the nozzle, and using a sharp knife, carefully cut off the dome of the flexible decorators filler, taking care not to damage the thread. Screw the nozzle on to the cartridge.
4. Cut off the tapered end of the nozzle at a 45° angle, to a width matching the gap to be filled.
5. Fit the cartridge into the cartridge gun by pressing the release plate and pulling out the plunger. Insert cartridge and repeatedly squeeze the trigger until the filler appears.
6. Place the nozzle at the start of the gap and gently squeeze the trigger. Push forward slowly, ensuring that contact is made by the filler with both sides of the gap. At the end of the run, release the trigger and press the plunger release plate of the gun.
7. Remove excess filler immediately with a flat blade to give a nice, smooth finish.
8. After use, ensure to wipe away any excess adhesive from the nozzle. Replace the cap.

PAINTING FLEXIBLE DECORATORS FILLER
- Painting of the filler should only be carried out once it has fully dried. Painting too early may lead to the paint cracking.
- For fine filling and for applications less than 1mm, painting may be carried out in as little as 30 minutes.
- When used for filling gaps around frames, skirting and similar, where the filler may have a depth greater than 5mm, drying times will be much longer. Leave at least 24 hours before painting.
HOW TO REMOVE
- Uncured filler: Excess uncured filler should carefully be scraped away using a knife and the remaining film wiped away immediately with a clean cloth, dampened with warm, soapy water.
- Cured filler: There is no adequate solvent; carefully cut away excess with a very sharp knife. Do not use solvent to remove product from skin – use soap and water.
FAQs
As soon as it is dry through. For thin layers less than 1mm, this could be as little as 30 minutes in good drying conditions. For thicker layers and less than ideal conditions, it could take a full day, or even longer if it’s very thick. Since this sealant shrinks as it dries, the surface stretches and this could crack a paint film if it was applied too soon.
Excess sealant should be carefully scraped away using a knife and the remaining film wiped away immediately with a clean cloth damped with warm soapy water. Set sealant can only be removed mechanically using a sharp knife or scraper.
- Caulk is for neat finishing indoors, like filling gaps around skirting boards or window frames before painting. It dries hard and can be painted over.
- Sealant stays rubbery and flexible, making it perfect for kitchens and bathrooms where gaps need to stay watertight. It won’t usually take paint, but it stops leaks and handles movement well.
Think of it this way: caulk for a paintable finish, sealant for a waterproof seal.
You should caulk before you paint. EVO-STIK Flexible Decorators Filler can be painted over, so it makes sense to caulk before you paint. Occasionally, people may prefer to prime the surface before a caulk application. However, caulk should always be the first step before topcoats of paint are applied.
No – we recommend using a sealant for bonding the bottom of skirting boards instead of caulk. Caulk is best applied to the top of skirting boards.
