Method of restoring used or deformed floor surfaces particularly of wood, such as stair steps

1. A method for refurbishing worn and/or deformed floor surfaces, particularly of wood, such as stair treads, by depositing a cold setting filler compound on the worn surface, characterized in that it comprises the following stages : - the surface to be treated is prepared by increasing its roughness, in particular by slightly lifting the fibres when the surface is made of wood ; - formwork (7) is placed round the free edges of the surface being treated, with one or more formwork sides (8, 8c) placed above the level of the least worn portions of the surface being treated so that the formwork is made suitably leaktight ; - the above-mentioned filler compound comprising a cold setting synthetic material and being sufficiently fluid to fill the formwork volume, is poured into the above-mentioned formwork and by gravity forms a free horizontal surface (14) and then can gel rapidly in no more than 5 to 10 minutes : - and then the formwork sides are removed. Le procédé de l'invention permet la réfection des surfaces en bois usées et déformées et une remise à neuf sans démontage. Il consiste à couler dans un coffrage souple (7) une matière de rechargement liquide s'accrochant aux fibres du bois de la surface de la marche (1) convenablement préparée initialement par rabotage de façon à améliorer l'accrochage. La coulée de la matière de rechargement liquide réalise à la fois la remise à niveau et la moulage à neuf des éléments anciens en bois. Parmi les applications les plus intéressantes de l'invention on peut citer la réfection des marches d'escalier en bois usées et déversées ainsi que le traitement de parquets de salles d'eau.
