Waterproof neoprene latex emulsion epoxy grout construction steps

1, the conditions of use 1. 1 waterproof neoprene latex emulsion epoxy grout construction environment suitable for 10 - temperature 35 ℃, when construction environment temperature below 5 ℃, the heat insulation measures should be taken. Should not be in the wind, rain or sunshine point-blank in high temperature environment construction. 1. 2 waterproof neoprene latex emulsion epoxy grout should not be in the epoxy curing period less than 3 d cement grout or concrete base construction. 1. 3 when alone buy neoprene latex emulsion, site: when the mixed epoxy grout cement mark should be not less than p. o42。 5 the cement, aggregate USES is not greater than 2. 5 mm clean river sand and quartz sand, cement, sand ratio of 1:1 for the bases - 2, a ton of epoxy grout acrylic-emulsion dosage is 38 - 50, in order to make epoxy grout to corresponding product operational performance and obtain a better construction, can add appropriately stable agent, defoaming agent, ph regulator and other additives. 1. 4 when using finished product epoxy grout, chloroprene latex dosage can reduce accordingly, minimum weight epoxy grout can be as low as 15 20% 2, base surface treatment: 2. 1 at the grass-roots level surface should be smooth, rough, clean, no oil, dusting, empty drum, cracks and other phenomenon. Before the construction state of application of high pressure water washing and keep moisture, construction can not have water 2. 2 on the interface of steel construction, the base surface should be without oil, rust, rust removal level appropriate for the ST3, weld and overlapping parts, application acrylic-emulsion epoxy grout after leveling, during the construction. 3, the preparation of epoxy grout: waterproof neoprene latex emulsion epoxy grout appropriate USES artificial mixing, when the mechanical mixing, agitator vertical double entry should be used. When mixing shoulds not be vigorous agitation; Should not be repeatedly stir and add water, mix well after the configured epoxy grout should be finished within 1 h. 4, use steps: 4. 1 shop with chloroprene latex emulsion waterproof coating should be taken before epoxy grout chloroprene latex cement slurry net again, net pulp 100 - according to the cement 200: acrylic-emulsion 38 - 50 the proportion of adding, according to the construction need adding suitable amount of modifier, epoxy coating while paving chloroprene latex cement grout. If the face is coarse, level off, meet the construction conditions, can also apply directly with good waterproof neoprene latex emulsion epoxy grout. 4. 2 epoxy grout shoulds not be too great a construction area, the article should be or block staggered construction, each area should not be greater than 12 m2, strip width should not be greater than 1. 5 m, seams or piecewise staggered construction time interval should not be less than 24 h. Slope surface seam wood or PVC should be set in advance at the grass-roots level, after waiting for epoxy grout plaster can take out the seam and the seams after 24 h. Layered construction, seam location should be staggered. 4. After 3 neoprene latex cement grout paving epoxy pressure should immediately wipe, and should be erased at a time, should not be repeated with pressure. Meet with bubbles should prick compaction, surface should be compacted. 4. 4 on the facade or on construction, the layer thickness is greater than 10 mm, face to face should be layered construction, appropriate for 5 - layered plaster thickness 10mm。 Stay a layer of dry to non-stick hand before the next layer can be construction. 4. 5 chloroprene latex emulsion waterproof construction after 12 - epoxy grout After 24 h, appropriate net followed by a layer of cement slurry on the surface. 5, after curing epoxy grout chloroprene latex cement plaster, surface dry to non-stick hand namely spray or covering plastic film, bag for maintenance. Around the plastic film should be sealed, maintenance cycle is best moisture curing 7 d, natural curing 21 d. 6, when the shop used to block material, 6. 1 block surface should be water soaked the piece of wood in advance after 2 h, dry the water can be paved. 6. 2 pieces of material combination of layer thickness and ash seam width should be consistent with the table below piece types are combined with layer thickness ( mm) Ash seam width ( mm) Acid-proof brick/heat-resistant brick 4 - 64 - Natural stone material thickness or less 306-6 86 - 88 - Thickness > 15-3010 158 - 156. 3 paving acid-proof brick knead crowded method should be adopted; Pavement thickness is greater than or equal to 60 mm natural stone material can be used when the slurry method. 6. Shop 4 block material should be at the edge of the base on besmear brushs net pulp paving, the combination of tile layer and mortar joint should be close-grained, and measures should be taken to prevent material movement, continuous pavement height of the facade tile with cement, epoxy grout hardening time, and should prevent the piece of wood compression deformation. 6. Shop 5, block material, mortar joint should be fill compaction, mortar joint surface should be smooth, and should clean up of the excess epoxy grout on the piece of wood.
