Submission Description: Plastering and Skim Coat

② Based on item 9 of Plastering Specification, there are two coats of plastering with total thickness is 19mm Why is your MOS 15mm (page 11/121)?

③ Page 12/121: The cement bags are stored on slab with 05 bags height, it means that about 500kg/m2 Please check with allowed live load of design whether it is overloaded for slab?

④ Mortar which is used for spatter-dash has to mix with bonding agent Sika Latex

⑤ Item 5.15; 5.16 are belonged to brick work MOS Why does SSY indicate in plastering MOS?

⑥ Item 5.25: Tolerance in plane is 10mm per 3m is not accepted

Since based on TCVN 5674-1992 it only allowed 2mm per 2m

⑦ Metal lath has to be applied before plastering at positions where brick wall is cut for installing concealed conduct Please show the typical detail of this case

⑧ It is not allowed to apply dry mortar on wet mortar which has high slump in order to avoid crack and hollow

⑨ For RC wall without plastering: Please state how to control to plastered layer of brick wall and concrete bare surface of RC wall are in line? And please provide detail of joint between plastered layer of brick wall and concrete bare surface of RC wall?

① Cement : sand= 1:4 is correct according to Specification Clause “plastering & Wall Tiling”

② Internal wall thk is 19mm, external wall thk is 20mm

③ Slab can bear 450kg/m2 according to structure design brief 7 th page, so within 9bags in 1m2 is safe

④ Revised Bonding agent mixed with cement mortar for plastering

- 1 Cement bag, to be batched in 2 buckets (the 18liters – bucket)

- Sand: 8 buckets

- Water: 29 litre

1 5 Lim, RPLLC There are groove line for external wall, please include installation of groove line strips in external plastering works Inserted accordingly (Pg 78)

1 8 Tuan/Tan, ICIC Please use sand specification TCVN7570:2006 & TCXD127:1985 for mortar We will comply

1 9 Tuan/Tan, ICIC Please provide treatment tie line between plastered brick wall and bare concrete surface (without plastering) because shrinkage crack will be

1 10 Tuan/Tan, ICIC SSY is required to test mortar (test result of trial mix) before using We will comply
