Applicable substrate: Concrete block siding board
1.下地処理
A. In the case of concrete or block base...
Inspect the base and dry thoroughly after cleaning.
B. In case of siding board base...
継ぎ目はしっかり固定し、下地が動かない様準備して下さい。
※ポイント※
◎施工は雨天時などを避け天気の良い日に行って下さい。
◎寒冷期に施工する場合、気温が5℃以下の時、施工後養生中に5℃以下になることが想定されるときは施工を行わないで下さい。
2. Installation of hook screws
Check the position of the pin on the back of the keystone accessory, and insert the stainless steel corkscrew screw into the base in the position that will catch on the pin.
※point※
Since keystone accessories are handmade products, the position of the pins will vary from piece to piece, so please check the position before hammering in the screws.
3. Paste
Apply adhesive (2-part epoxy resin for exterior use recommended) to the back of the Keystone accessory and attach it. If you hook the pin onto the screw you previously drove in, you can attach it safely until the adhesive hardens.
4.Curing
Be sure to allow sufficient time for the adhesive to harden.
5. Painting
It is not a problem if keystone accessories are not painted, but if there are color coordination instructions or you are concerned about dirt, please paint them.
