Product Information

Unlike silicone, acrylic latex caulk doesn’t release fumes, and is paintable. And because of its high elasticity, it’s great for sealing wood joints. Once the acrylic latex caulk has been applied to the desired surface, it is ready to be painted. If the surface is not clean, it will interfere with the bonding of the sealant.

If the surface is damp, you’ll need to leave the area to dry naturally, so a fan can help speed up the process. Both materials should be exposed to temperatures of at least 5 degrees. If the temperature is too cold, silicones will freeze. And neither will cure well in extremely cold temperatures. This is why polyurethane caulk cures faster than polyfilla.You must wait for Polyfilla to dry in 4 to 24 hours. The better the conditions, the faster the drying time. Can I Use Polyfilla in Large Holes Additionally, ensure that all surface dust is removed so that it does not interfere with the adhesion of the applied layers. Can you Apply Polyfilla with a Brush?

If your gun doesn't have this, use a Stanley knife to cut the end of the tube before attaching the nozzle. Be careful not to cut too far as you won't leave enough threaded area to attach the nozzle and it will come off. Next, cut the nozzle at a 45-degree angle. This gives you a nice nib to work along the edges. Put the caulk tube into the gun, but take care not to press the plunger in until you are ready or caulk will start coming out. 4. Do a test run Although Polyfilla is great in most situations, it should not be used for external wood repairs. This is because Polyfilla will not last when exposed to the elements. It may soak up moisture meaning it won’t harden and this could cause the wood to rot. To prevent Polyfilla from showing in paint, use a sealant to encapsulate it before finishing with the topcoat. Other precautions include sanding down any raised areas after drying and using a primer before applying the final coat of paint. If the area that needs to be filled is small then Polyfilla could be used. However, if you would like a seamless finish using a stain then it’s better to use a wood filler. Polyfilla can be painted over but the type of paint may impact the final results.

Yes, Polyfilla can be used to repair small holes in MDF. It can also be sanded and painted once dry. However, Polyfilla isn’t a good choice for a penetrating finish so keep this in mind if that is what you plan to use on the MDF. It discolors if left unpainted, but after fully curing, it can be painted to hide any unsightly discoloration. Frequently Asked Questions (FAQs) -What is the difference between caulk and polyfilla?
