もシ１＝常Ｇこ名かつ！こ。Conventional urethane waterproofing methods include waterproof urethane resins (non-tar urethane, color urethane, tar urethane).
There were 5 to 7 cases in which each was used separately. Also, the coating thickness for each process is approximately 1- to 4-z gloss or 4 or more in many cases. The urethane resin itself

In this case, if the coating thickness for each process is 1 m or more, 2 layers and 3 layers will be coated. Up until then, there were many cases where I would have to cut 1 + 1 +. Also, pinholes, fukuro, etc. are 4-engineered by δ/AE, but shi1 = regular G name and cut! child.

Due to the cracks that occur on the waterproof base by applying an overcoat of approximately 1 m1, the first layer is extremely thin, so the cracking force <thf]υ11 In this case, only the first layer breaks quickly. This is a waterproofing method that creates a waterproof base for the second and third layers (because the tearing force of the crack is not directly transmitted, it is extremely difficult to break even if a crack opens). Also, by rubbing it in thinly, the tightness will be improved and pinholes, flecks, etc. will be much less likely to form.

第二及び第三層は仲々切れない状態になる訳で留る。The waterproof layer formed in this way is the first layer of urethane.
■■ Because the thickness of the second and third layers is extremely different, if a crack occurs, only the extremely thin first layer will break quickly.
The second and third tiers remain in a situation where they cannot get along.

Moreover, by rubbing the first layer very thinly with a rubber trowel, etc., the density is improved, and by creating a completely thin film between the waterproof base and the base, moisture, air, etc. from the base will rise up. As a result, it becomes extremely difficult to create pin poles, fukuro, etc.

Very good followability to cracks.

Rub a thin layer of waterproof urethane powder and non-tar urethane onto the waterproof base of the building with a rubber trowel, etc., and after curing, apply a medium coat of non-tar urethane on top of that, and then apply color urethane with good weather resistance on top of that.
