p********f 发帖数: 5148 | 7 头次在这个版发贴,各位多关照哈。
正在考虑做back patio, side walkway, 和front entryway (门外的). patio and
entryway 都做成stamped concrete. side walkway regular concrete.
面积 stamped concrete 649 SF, regular broomed concrete 184 SF.
找了两个公司。一个尚未开价,另一个开价为 stamped concrete $10/sf, regular
concrete $7/sf.
另外原有的砖铺patio和entryway都要remove. 合起来最低价只能砍到$7000.
我在美东。这个价钱如何? |

G*****m 发帖数: 5395 | 10 我原先的表面不水平,所以需要铺水平的话,深度不一样
你的水泥已经完全干了?没干的话直接加cement:sand mix
如果已经完全干透了,可以用concrete bond+ cement:sand mix
或者你去HD/lowes看看,有top resurfacer的,我买的resurfacer不用bond,setting
time 3hours
用concrete repair也可以,不过concrete repair一般是rapid set: 20m-1h
你动作得快点
还是没有完全看懂. :(
我原来铺了4inch的ready mix concrete.
现在是不是再上0.5inch的resurfacer就行了? |

想问问大家,hollow core block的有什么坏处,另外对以后再卖房,房子的value有什

台阶下到地下室,感觉很鸡肋,而且感觉不安全。这个住进去以后会不会有什么麻烦?

楼上的plywood sheet可以直接钉,楼下的是concrete,各位同修给支支招怎么固定
plywood sheet,预备了liquid nail construction adhesive,可是看了一堆youtube

这个cedar因为在closet里边没有行走的摩擦,所以就用的是一般的cedar lining

I want to install engineered wood on concrete floor, contractor said I need
concrete sealer/moisture barrier between the engineered wood floor.
But a google search on lumber liquidor/lowes indicate I should be free of
sealer
Subfloors must be clean and free of dirt, curing compounds, sealers, drywall
mud, paint, wax, grease, urethane, or other materials that may affect the
integrity of the flooring material or adhesives used to install the flooring

我买的resurfacer是0-0.5 in
0.5-2in的用cement:sand 1:2

那么在原来的基础上, 只需要加这个resurfacer就够了? |
