There are several ways to dismantle the plastic sill. Gently drop a layer of plaster under the window sillom. Take a knife with a rigid blade and cut off the layer of foam remaining after installation of the plastic construction. Do it slowly and very carefully below a frozen layer of foam broke. Now pull the sill itself, slightly dipping down.
There is another option to dismantle the plastic sillwithout taking off the slopes and not beating the plaster underneath. Take a hacksaw and saw through it a layer of foam, then similarly remove the liquid plastic that was left at the junctions of the slopes and the sill. Cutting off this layer, carefully pull the sill itself. If the design does not give in, even saw a little layer of foam under the window. Then again pull the sill itself. Restrict physical effort not to smash the window sill.
To build up the ledges silland it is possible without dismantling the structure. To do this, take the plastic trim structures the required size and color. Then attach them on both sides of the silland with the help of hangers. Carefully apply the joints with liquid plastic so that it was not bumps, roughness and other defects. Allow the solution to dry. Then treat the surface with fenasalom.
For installation of plastic window silland uses a special glue or cement. The design also can be mounted on the screws with metal base. Install the window sill so that the length of the silland exceeded the width of the window opening together with the slopes.
