Poly Gap Filler Sealant Multipurpose [White]

A flexible multipurpose gap filler, to fill gaps around cornice, wall joints, skirting board, window and door frames where where movement causes ordinary fillers to crack or fall out. For use on: Wood, brick, aluminium, glass, plasterboard, ceramic tiles and painted surfaces (INTERIOR & EXTERIOR) Coverage: 30m/3mm bead. Dry time: Skins in 30 minutes at 25°C. Full cure in 7days. Ready to use: YES Available in: 475g Colour: White NOTE: Not for fine joints between tongue and groove boards or weatherboard overlaps. • Ensure surfaces are clean, dry and free from oil, dust, grease, flaking paint and old sealant. • Using caulking gun, push sealant ahead of nozzle forcing it onto the surface and into the joint. Ensure the sealant is touching both sides of the gap. • Smooth with wet finger or knife and remove excess sealant immediately with a damp cloth. • Allow sealant to skin approx 30 min before painting with water-based paints. • Allow to set for 48 hours if using oil based paint or if joint is large. • Some water-based undercoats and flat paints may crack on drying. Test a small section of sealant. Paint cracking may be reduced by using a vinyl/ acrylic semi glossed paint or oil based undercoats first, or by allowing the sealant to cure thoroughly before painting. • Do not use outside if rain is imminent, not for contantly damp areas. • Painting improves exterior durability. • Use Poly silicone sealants for a watertight seal or where movement is excessive. • Water clean up Q. How do I fill gaps between my wooden window frames and inside wall? A. You're dealing with two different materials here, plaster and wood. To allow for differential movement between them, use Polyfilla Gap Filler, wiping off any excess with a damp cloth. Q. I painted over the areas where I used Polyfilla Gap Filler and now cracks have appeared. Why has this happened? A. If the gap filler was not cured sufficiently before it was painted over, cracks can occur as the gap filler shrinks. To prevent this, allow 48 hours drying time when you are filling large gaps or painting with oil-based paints. Also, some water based undercoats and paints shrink during drying and as Polyfilla Gap Filler is flexible, it won't stop cracks appearing in the shrinking paint on its surface. Test the paint on a small section of gap filler and if this is a problem you can reduce cracking by allowing the filler to cure thoroughly or by first coating it with a vinyl/acrylic semi-gloss or oil-based undercoat. Q. Why does my gap filler keeps cracking? A. It is important to remember that the width of a gap affects how much the product can move. Fine cracks less than 2mm allow the gap filler to move only very tiny amounts before it may crack again. It is best to ensure that you have at least 3mm worth of product so you can maximise the movement capability of your joint.
