Mathys Elastofill Acrylic Sealant 310 ml

Mathys Elastofill is an elastic, paintable acrylic sealant for closing gaps, cracks and splits, for interior use. Once the water has evaporated, a rubbery mass remains that stays elastic.

What you use it for

Sealing, pointing, filling, fixing, bonding and sealing on concrete, wood, metal, glass, rigid PVC, tiles, plasterwork and aluminium bitumen.

Properties

Permanently high elasticity (more than 900%), absorbs strong expansion and deformation, alkali-resistant, waterproof and highly resistant to ageing. Can be painted over with, among others, acrylic paints and with high gloss and satin alkyd paints. On Paracem and Pegamat, apply a coat of Porisol first.

Application

Apply the sealant with a hand gun in a wet layer thickness of no more than 10 mm. Cut fine cracks out to about 0.5 cm wide first; if the depth is greater than half the width, apply a backing rod first. On porous surfaces use a suitable primer, on PVC Primer 44 HS and on metal and glass diluted Noxyde. Apply between 5 and 35 °C. Smooth joints off with a finger or a cloth with soapy water. At 20 °C the sealant is tack-free after 3 hours and paintable after 1 day (layer thickness 8 mm); fully cured after about a week. Clean tools and splashes with water while the sealant is still wet.
