Glass mosaic phenomenon and reason analysis in construction
1, paste mosaic 300 * 300 obvious separation
Reasons: 1 ) paper shrinkage problems;
2 ) static color problem;
3 ) paving joints have good.
In 2, mosaic back bottom phenomenon
Reason: cement color selection problem.
Glass mosaic itself has a transparent or translucent characteristics, so the top choice of white cement, avoid the black cement anti bottom phenomenon.
In 3, mosaic paste after cracking
Reasons: 1 ) the mosaic itself too brittle;
2 ) construction too hard.
In 4, a mosaic pattern on
Reasons: 1 ) the problem of stickers;
2 ) the factory before the test.
In 5, mosaic paste after the paper off phenomenon
Reasons: 1 ) before fully wet base construction;
2 ) touching the seam is not serious.
In 6, mosaic paste found hollowing phenomenon
Reasons: 1 ) primary hollowing didn't check, basic cleaning is not clean;
2 ) prior to the construction of not fully wet grass;
3 ) cement paste paste is not full and uneven;
4 ) affixed wall bricks without iron cast;
Sub tapped or tap is not uniform.
In 7, mosaic paste uneven phenomenon
Reasons: 1 ) the grass-roots flatness didn't check;
2 ) construction of base paste mud layer too thick, not just with ash, cement paste paste thickness uneven;
3 ) no use trowel uniform tapped.
In 8, mosaic paste after dislocation phenomenon
Reasons: 1 ) before the construction, no good seam;
2 ) construction not to sew;
3 ) remove the paper before the paper construction method not pat;
4 ) paper shrinkage problems;
5 ) paving control is lax, no good crack and the paper uncovering no adjustable suture.
In 9, the wall is dirty
Reasons: 1 ) the paper uncovering no residual paper wool, paste slurry timely clean;
2 ) after the wiping joints without residue brick surface water thoroughly clean white mud.
