Water-packed water, water-wrapped sand 5 different shapes of construction methods, all!

Water-wrapped water, water-wrapped sand with its excellent performance and atmospheric appearance, is widely used in the exterior wall, compared to marble has the following advantages:
1. lightweight safety: very light physique, about 1KG/m2, quite real stone paint 1/6, dry hanging stone 1/40, 1/20 of the brick, without any security risks.
2. Construction is fast: each person can operate about 120m2 per day;
3. Low pollution: colorful paint is water-based paint, environmentally friendly and smooth waterproof, dust will not penetrate the sediment

.
4. Wide range of use: because it is a coating product, so the use of small limitations, the substrate can choose concrete, PC board, ALC plate, asbestos plate and some complex shape of the building parts can be.
5. Cost: the cost is slightly higher than ordinary real stone paint, far lower than the stone dry hanging.
water-wrapped water, water-packed sand construction process
water-based imitation stone multicolored paint construction applications are generally divided into two systems, namely, sheet finish applications and building wall applications. The plate is applied with insulation decoration board and other building sheet, and the building wall is applied with the exterior wall level wall and the attachment three-dimensional finish.
construction process is applied on the
sheet:
sheet substrate treatment - spraying applicable interface agent - need to do intermediate coating - spray color primer - repair treatment - spray imitation stone paint main paint - spray cover paint.
application of construction process on the wall has three kinds:
1, flat concave seam construction process:
base surface flat - sub-grid, bullet line, thick tape - solid tape, cornering - batch scraping mortar putty (styling) ) - Batch scraping flexible putty (find flat) - polishing, watering, tearing tape - Rolling interface agent - Rolling coloring primer - Closed non-spraying part - Spraying imitation stone paint main coating (1 to 3 times) - Polishing, Repair - roll cover paint - roll cover paint - glue, finished
2, flat seam construction process:
base surface flat - cornering - batch scraping mortar putty - batch scraping flexible putty (find flat) - sub-Grids, bullet lines, trace lines - thick tape - Roll-on interface agents - Roll-on color primers - Spray imitation stone paint main coating (1 to 3 times) - patch, tear tape - Roll cover paint - roll cover paint - finished.
3, grain surface concave seam construction process:
base surface flat - angle - batch scraping flexible putty (find flat) - sub-grid, bullet line, trace line - thick tape, solid tape - rolling interface agent - according to design requirements of the construction of the middle layer - roll color primer - spray imitation stone paint main coating (1 to 3 times) - repair, tear tape - roll cover paint - finished paint.
the application of construction process on the facade is:
substrate according to the design requirements - roll coating interface agent - according to the design requirements of the construction of the middle layer - roll color primer - spray imitation stone paint main coating (1 to 3 times) - roll cover paint - roll cover paint - finished product.
specific operating methods for water-packed water and water-wrapped sand construction
environmental protection
1, pre-construction inspection should be protected places.
2, construction deployment, window sills, door edges, trees and certain ground, such as potentially contaminated places with plastic film protection cover.
the grass-roots inspection and
1, a comprehensive inspection of the grass-roots wall whether there are cracks, empty drums. Eliminate empty drums, semi-shedding, loose substations.
2, the old wall should be cleaned, remove the old coating, floating ash and so on.
3, with wire brush, sandpaper, etc. to remove floating ash, grease and other powder attachments.
4, if the wall floats more gray, the use of water cannon washed the surface of the outer wall.
5, cracks, empty drum depressions with external wall putty to level, maintenance 5-7d.
6, such as insulation on the finished plate construction should ensure that the surface of the plate is flat without burrs, if there are burrs need to be sandpaper sanding.
batch scraping putty
1, in the treated substation with flexibility to find flat putty batch scraping 1-2 times, each time putty should not be too thick, to the wall flat for the purpose.
2, tiles, mosaic walls, please fill the interface agent, and then use tiles to renovate putty full batch again and again to find flat.
3, sanding the putty surface with water, removing the surface fuchsium burrs and so on.
4, putty construction should be maintained 15-20d (23±2 degrees C), so that the water content of the grass-roots <10%, PH value <10.
5, batch scraping flexible glossy glue 2-3 times, each time the construction interval of 12h (23±2 degrees C), after the completion of the drying 24h (23±2 degrees C).
6, sanding the surface with fine water, so that its surface is flat and smooth, to paint construction to provide a good substing.
apply a special
lotion 1-2 times evenly with a wool roller or spray gun.
2, the primer is completely dry (6h/23±2 degrees C) can be transferred to the next process.
spray water bag water bag sand colorful imitation granite paint
1, with a special spray gun evenly sprayed colorful paint 1-2 times. (Water-packed water caliber is generally around 3.0, water-packed sand caliber at 3.5-4.0)
2, each construction interval of 12h (23±2 degrees C).
24h/23C after spraying of 3rd and ± paint.
spray-painted mask
1, with spray-painted gun evenly applied mask varnish 1-2 times.
2, at intervals of 4-6h/23±2 degrees C.
coating maintenance
coating completely film hardening period of 7d/23±2 degrees C, during which no one may be caused by damage and so on.
paint after the construction of cleaning
1, a day after the completion of the process, remove the relevant parts of the protective covering film.
2, clean, clean the relevant parts and the ground.
the construction of paint
1, colorful paint do not stir hard.
2, not mixed with other substances.
3, can not be diluted with water.
4, open the barrel after the paint as long as possible to use up.
