3 primary treatment and 3.1.1 must be strong grass-roots, dense; strength must be tested and shall meet the design requirements. Do groundwater seepage, uneven subsidence. Prohibited from the sand, shell, crack, Honeycomb and so on. 3.1.2 The primary surface should be smooth, its flatness should check 2m straightedge and shall meet the following requirements: 1 when the anti-corrosion surface layer thicker than a thin coating of epoxy floor construction at 5mm, allows the gap should not exceed 4mm; 2 When the anti-corrosion layer thickness is less than 5mm professional epoxy floor coating thin, allowing the gap should not be greater than 2mm 3.1.3 grassroots must be dry when the depth of 20mm thickness of the layer, the moisture content should not exceed 6%; when using When the moisture-curing type material; moisture content above limitation may not thin coating of epoxy floor paint, but the surface may not have water seepage, floating and water; when designing humidity have special requirements, design requirements should be constructed. 3.1.4 grassroots slope must be tested and shall comply with the design requirements of the epoxy floor coating thin, its deviation should be allowed to slope length ± 0.2%, the maximum deviation is not greater than 30mm. 3.1.5 and load-bearing structures, and other important concrete . Pouring water template should be used once made large when using steel template, the choice of release agent should not contaminate the grassroots 3.1.6 When the primary surface material when the block paving construction, Yang angle should be made at right angles to the grassroots;. make other When the type of anti-corrosion construction, Yang angle grassroots ramps or fillets should be made. 3.1.7 surface through grassroots conservation, not white precipitate. 3.1.8 base surface must be cleaned before construction, the primary surface treatment methods should comply with the following provisions; 3.1.10 Where anti-corrosion layer through pipes, casing, aside tie, embedded parts, should be set up in advance or remain buried. 3.1.11 overall structure grassroots anti-corrosion surface treatment should not be made of leveling. When it is necessary to find the usual intake, treatment should meet the following requirements; 1. When using fine aggregate concrete usually find the strength rating of not less than C20, thickness not less than 30mm 2 when the grass roots must find usually with cement mortar, should be coated with a layer of concrete interface treatment agent, then the design thickness leveling. 3 When the construction process should not carry out such operations, can be resin mortar or polymer cement mortar. 3.1.12 usually find when using cement mortar, the surface should be compacted, smooth, not beat, and roughened. 3.1.13 After leveling layer surface maintenance of non-cracking, sand, delamination, Honeycomb and other defects. 3.1.14 When the surface layer of cement mortar masonry structures wipe the surface must be flat, without from the sand, shell, cellular, Pock and other defects. Before coating the substrate quality checks in order to design a reasonable paint scheme and focus to take some quality control measures based on conditions on the ground.
