Description
Technical Field
The invention relates to the field of building repair, in particular to a construction method for integrating waterproofing, renovation and decoration of old tile roofs.
Background
Most of buildings with 6 floors and below built before 2000 years are brick-concrete structures, tile roofs are adopted mostly, the traditional tile roof structure is adopted, waterproof layers are arranged below heat preservation layers and fine aggregate concrete protection layers mostly, if the original structural form is maintained, the original protection layers and heat preservation layers need to be removed, the waterproof layers are laid again, the heat preservation layers and the protection layers are remade, noise and dust pollution can be caused, huge waste is caused, the construction period is long, and the construction cost of dismounting labor and the like is high. Most of the old buildings are in a living state, if the roofs are completely dismantled, more serious leakage can occur in the rainy days in the construction process, and the feasibility is low.
The domestic patent 201410032624.1 discloses a construction method for applying single-component polyurethane to renovate and reform old hard waterproof roof, which comprises leveling a base layer by using polymer mortar, sealing joints by using caulking grease or special caulking strips for foam by using caulking materials, using acrylic mortar as primer, brushing water-based high-solid aromatic polyurethane waterproof paint with the thickness of not less than 1.8mm on the surface of the primer as a main waterproof layer, and brushing weather-resistant aliphatic polyurethane waterproof paint with the thickness of 0.2mm on the outer side of the main waterproof layer as finish paint. The construction method applies the water-based high-solid aromatic polyurethane waterproof coating to the renovation and reconstruction of the old hard waterproof roof, the polymer mortar is used for leveling the base layer, a blade coating process of the polyurethane waterproof coating is adopted, the leveling scheme and the blade coating scheme are not suitable for the uneven structure of the tile roof, and are suitable for the construction of the relatively flat hard roof such as a concrete roof, and the water-based high-solid aromatic polyurethane waterproof coating is used as a main waterproof layer and matched with the weather-resistant polyurethane finish.
Domestic patent 201710340824.7 describes a construction method for renovating old roof with waterproof, which adopts a two-cloth one-coating process node, uses 0.5-4mm water-based non-curing coating and 0.1-4mm non-woven fabric enhancement layer as a main waterproof layer, and uses 0.5-3mm exposed water-based acrylic coating surface layer to realize the exposed function. The method can reduce pollution, noise and lifting troubles caused by the removal of the protective layer in the traditional maintenance engineering, and can reduce the construction cost and shorten the construction period to a certain extent. The construction method takes the water-based non-curing coating and the non-woven fabric as the main waterproof layer and the water-based acrylic coating as the surface layer, and the non-woven fabric reinforcement layer is required for node treatment and large-area construction, so that the construction method is suitable for large-area paving and pasting of flat roof. The scheme of using the reinforcing layer is not suitable for waterproof construction of tile roofs and other complex surfaces, and a water channeling channel is easily formed due to the fact that a two-dimensional plane material cannot be completely attached to the tile roofs with irregular three dimensions.
Therefore, in order to solve the above problems, the present invention urgently needs to provide a construction method for integrating waterproofing, renovating and decorating old tile roofs.
Disclosure of Invention
The invention aims to provide an exposed polyurethane waterproof coating and a construction method thereof on an old tile roof, and solves the technical problems that the existing process can not effectively avoid coating flowing, material accumulation at low positions, uneven thickness and long-term exposure weather resistance of a continuous and uniform coating on an uneven complex surface in the prior art.
The invention provides a construction method for integrating water resistance, renovation and decoration of an old tile roof, which comprises the following steps:
cleaning a base layer;
and (3) repairing nodes: sealing the seam, the crack, the screw and the damaged position by adopting a sealant;
and (3) spraying treatment: after the sealing glue is cured, spraying waterproof paint compatible with the sealing glue on the roof;
and (5) maintaining the waterproof coating.
Preferably, the waterproof coating is a waterproof coating with a sag resistance function, and the sealant is a polyurethane sealing sealant or an MS sealant.
Preferably, the waterproof coating is aliphatic exposed single-component polyurethane waterproof coating, water-based acrylic acid or water-based polyurethane.
Preferably, the roof is sprayed with the aliphatic exposed single-component polyurethane waterproof coating at least once.
