Paints are commonly used as indicator detection methods.

First, film thickness check
should use needle puncture method every 100 square meters of thorns three points, with a ruler to measure its height, take its average, film thickness should be greater than 2 mm. Use a colored pen as a marker when piercing for patching.
II, break elongation inspection
in waterproof construction, supervisors can go to the construction site will stir good material, divided into multiple brushes on the flat glass plate (glass plate should be waxed first), film thickness 1.2-1.5 mm After 7 days of placement, soak in 1% alkaline water for 7 days, and then bake in an oven at 50 degrees C and 2 degrees C for 24 hours to do dumbbell stretching experiments, requiring an extension hold rate of 80% (200% without treatment)
.
. If the standard is not met, it means that the proportion of emulsion in the construction is insufficient.
Thredi, water resistance inspection
the paint will be painted on the cement block many times, film thickness of 1.2-1.5 mm, placed for 7 days, put in 1% alkaline water soaked for 7 days, not layered, not empty drum for qualified.
Sear, impermeable inspection
under conditions, the application of instrument testing, the method is to paint proportionally, divided into multiple brushes on the glass plate (glass plate waxing first), thickness of 1.5 mm, sit still for 7 days, and then put people in the oven 50 degrees C±2 degrees C baking 24 hours, after removal and placed for 3 hours, do impermeable water experiments, impermeable 0.3mpa. Keep it leak-free for 30 minutes to qualify.
If the conditions do not exist, you can use visual inspection to check the waterproof effect, the method is to paint the paint 4-6 times to non-woven fabric, after drying out (about 24h) film thickness of 1.2-1.5 mm, to make a slow box shape hanging empty, but not left dead corner, and then 1% alkali water plus human box, 24h no leakage qualified.
, bonding force inspection
g-type polymer waterproof mortar, can be directly formed "8" word mold, 24 hours after molding. Soak in human water for 6 days, indoor temperature of 25 degrees C± 2 degrees C dry maintenance for 21 days, do bonding experiments. g-type waterproof mortar, gray: water: glue: 1:0.11:0.14, g-type waterproof mortar is 2.3mpa.
the r-type paint and into sesame sauce, and good paint applied to two and a half "8" word mortar blocks, placed for 7 days to do bonding experiments, r-type ratio (high bomb), powder: glue: 1:1.4; The r-type is 0.5mpa and the bonding indicator is qualified or equal to .
6, low gentleness inspection
waxing on the glass plate, the construction site stirred good paint is painted on the glass plate many times, film thickness of 1.2-1.5 mm, after drying off the glass plate, placed indoor (25 degrees C±2 degrees C) 7 days, then cut off the length of 120-150 mm, width of 20 mm bar, the refrigerator temperature to -25 degrees C, put the test film in the refrigerator for 30 minutes, with a diameter of 10 mm round rod is wrapped once, no cracks for qualified. Cracks indicate that the emulsion is low and gentle enough.
: g-type waterproof mortar only to do routine inspection, indesperable, bonding strength test. Samples should be sampled at the construction site to do the test film, brush test film application cross-cutting method. The thickness of each coating film is 0.25-0.35.
