uPVC window repair with HB42

A crack between the windowsill and the window of a house conversion project has allowed water to penetrate and a small repair to the MDF windowsill needs to be carried out.

After making sure the windowsill was dry, the crack has been filled with HB42 Sealant and Adhesive then smoothed with a finger smeared in washing up liquid. The windowsill is now ready for painting as required. HB42 Sealant and Adhesive will form a good flexible seal and can be over painted with acrylic paint.
