First, grass-roots conditions:
1. To remove the grass-roots level surface debris, oil, sand, gravel surface protrusion, swelling on the skin, such as mortar should be clean, clean-up work must be carried out at any time during the construction.
2. In order to ensure a solid bond coating on the surface of the grass-roots level, the requirements of the leveling layer should have sufficient strength, smooth surface, not sand, not skin.
3. Not the grass-roots level moisture requirements if Mingshui noodle-based, can work to eliminate.
4. Kok Yin and Yang should be put into a cement mortar arc angle.
Second, the process:
Noodle-based treatment - → Tu at the end of glue - → polymer preparation of cement-based waterproof coating - → node positions to strengthen the handle - → Large scratch coating layered polymer cement-based waterproof coating - → received the first waterproof layer - → Organize acceptance
Three, the construction steps:
1. Noodle-based treatment: Using a shovel, broom and other tools to remove the construction waste, such as cleaning solvent necessary when stains, grass-roots level there is defect or running sand situation, new trim, looking at the site of Yin and Yang angle normal arc made.
2. James at the end of plastic: the grass-roots poor flatness, the modifier in the mixture at an appropriate amount of water (the ratio of the general modifier: water = 1:4) uniform mixing, the coated surface at the grass-roots level to do BAYDERM.
3. Polymer cement-based waterproof coating preparation: first waterproof coating (in accordance with the modifier: cement weight ratio = 1:0.8) well prepared with a blender to even slight stirring, a mixture of non-aggregate to the use of ingredients Noodles and quantity in accordance with the completion of works arranged by the time of the labor force, with best materials should be run out in 40 minutes.
4. Node positions to strengthen the deal: by design or specification of the node positions (Yin and Yang Kok, construction joint, floor drain, etc.) brushing polymer to strengthen the cement-based waterproof coating layer, coating matrix material between an additional enhancement.
5. Large scratch coating layered polymer cement-based waterproof coating: scratch sub-vertical and horizontal direction of the polymer coating of cement-based waterproof coatings, one coating after coating should be one of the former do not form when the construction work (under normal circumstances, the two between layers of about 2 ~ 4 hours), to refer to non-stick, whichever is inconsistent.
6. Closed the first waterproof layer: polymer cement-based waterproof coating used many times received the first brushing or in sealed Seal Materials
7. Organize acceptance.
Fourth, note:
1. Each coating Tests should be conducted to determine the amount of coating per m2, the construction should be determined from the amount of material.
2. Follow-up material should be evenly Chiu asked about many times before and after the brush roll evenly, should not there is local deposition, elevation, slope down on brushing should prevent falling or too thick flow.
3. Have gel or rubber conjunctiva should not continue to use or incorporation of new material in use.
4. Finished Protection: waterproof coating completely solidified after passing inspection, it is timely to do a good job in protecting film, the follow-up procedures to prevent damage to the coating, thus affecting the overall performance of the waterproof layer of waterproof, should strengthen the construction of the educational work product protection of the formation of conscious awareness, at the same time take measures to ensure that the waterproof properties of the waterproof layer.
Friday, quality standards and testing methods
Master project
1. Modifier polymer mortar waterproof design requirements must be consistent with the provisions and norms.
Testing method: check the factory certification, quality inspection reports, measurement rehabilitation measures and on-site inspection report of the sample.
2. There is no waterproof layer coating leakage phenomenon.
Testing method: To observe the inspection or淋水, water testing.
3. Waterproofing paint and detail design requirements must be consistent with the provisions and norms.
Testing method: To observe the inspection and acceptance Record concealed.
General
1. Film quality. Waterproof coating layer with the grass-roots should be firmly bonded, surface formation, brushing uniform, non-flowing, folded, bubbling, and Alice Ruth carcass defects such as edge.
Testing method: To observe the inspection.
2. Coating waterproof layer should be in line with the average thickness of the design requirements, the minimum thickness of not less than 80% of design thickness.
Test methods: sampling needle method or measurement. |
