1. Substrate Ansa na-ayaresa
Hohoro substrate no ho ansa na wode ahyɛ mu, na yi mfutuma a ayɛ mmerɛw, ngo a ɛho ayɛ fĩ, ne atɛkyɛ a ayɛ mmerɛw nyinaa fi hɔ. Ebia substrate no yɛ nwini kakra nanso ɛsɛ sɛ nsu a egyina hɔ anaa mmeae a nsensanee a ɛyɛ tokuru (delamination) nni mu. Sɛ nneɛma a ɛnkɔ so wɔ soro no boro 3mm a, ɛho hia sɛ wodi kan yɛ levelling treatment na amma wɔannyaw boards no a wɔannye mmoa (a ɛbɛma voids aba) bere a wɔde ahyɛ mu akyi.
Di kan yɛ nhyehyɛe no ho nhyehyɛe na hyɛ akwankyerɛ ahorow agyirae, hwɛ hu sɛ board joints kwati mmeae a wɔde nsu gu mu mfinimfini ne mmeae a paipu anaa valve ahorow wɔ. Stagger board nkwaa no; kwati "cross-joints" a board ntwea anan hyia wɔ beae biako. Fa diamond cutting blade twa boards no sɛnea ne kɛse te, na twa opening ma pipes ne valves wɔ-site. Fa saa ntwitwiridii yi anoano yɛ mmerɛw na amma fiberglass mesh a ɛwɔ soro no ansɛe.
2. Board Fixing (Ɔfasu ne Fam Akwan) .
Ɔfasuo a Wɔde Sisi: Akwan mmienu a wɔfa so siesie wɔ hɔ-adhesive bonding nko ara, anaasɛ adhesive ne stainless steel self-tapping screws a wɔaka abom. Wɔ instɔlehyɛn a ɛwɔ stud/joist framework so no, wɔpɛ dual-fixing kwan (adhesive plus screws). Fa self-tapping screws a ɛwɔ washers di dwuma; gyinabea screws anyɛ yiye koraa no 15mm fi board no ano a ntam kwan yɛ 250–300mm. Countersink screw heads no sɛnea ɛbɛyɛ a ɛbɛtra ase flush ne board no ani kakra, nanso hwɛ hu sɛ ɛrenhyɛn board no cementitious facing layer no mu. Gyae 2–3mm ntrɛwmu kwan wɔ ntaaboo ntam na 5–8mm kwan wɔ ntaaboo no ase ne fam ntam na amma mpaapaemu a efi ɔhyew ntrɛwmu anaa nsu{15}}fata kankyee mu ba no ano.
Fam a Wɔde Sisi: Full-coverage adhesive bonding kwan no na wɔpɛ. Fa tile adhesive a ɛyɛ pɛ gu substrate no ne board no akyi nyinaa so, afei fa rɔba mallet bɔ so na ama board no ayɛ compact na hwɛ hu sɛ nsensanee biara nni ase a tokuru biara nni ase. Hwɛ 2–3mm ntam kwan a ɛda fam ntaaboo ntam na fa nhyehyɛe a ɛyɛ staggered di dwuma; wɔ fam mmeae akɛse ho no, ɛsɛ sɛ wɔde nkwaa foforo a wɔde trɛw mu nso ma. Hyɛ no nsow: Wɔabara koraa sɛ wɔmfa semɛnte a wɔde yɛ atɛkyɛ a ɛnyɛ den nni dwuma sɛ ade a wɔde kyekyere nnua no; ɛnyɛ den sɛ ahoɔden a ɛmfata a ɛkyekyere no betumi ama ntaaboo no atetew.
3. Nsuo a ɛmma nsuo ntumi nkɔ mu den ma nkwaa, emu/akyi ntwea, ne paipu a ɛkɔ mu (Anamɔn a Ɛho Hia) .
Board joints, emu ntwea, akyi ntwea, ne mmeae a paipu hyɛn mu nyinaa hia sɛ wɔhyɛ mu den. Nea edi kan no, fa atɛkyɛ a ɛyɛ mmerɛw a nsu ntumi nkɔ mu a wɔde siw ano hyɛ baabi a ɛda ntam no ma na fa fiberglass mesh tape a ɛko tia alkali-hyɛ mu; fa mesh tape no si nkwaa no so, fa trowel mia no mu kɔ atɛkyɛ no mu na yi mframa a ɛrehuruhuruw fi hɔ, na-bere a woayɛ no yare mfiase no akyi-fa atɛkyɛ a ɛyɛ tratraa a ɛnyɛ den gu so ma ɛkata mesh tape no so koraa.
Ɛsɛ sɛ wɔma ntwea a ɛwɔ mu no yɛ nsakrae a ɛyɛ kurukuruwa na ama adwennwen a wɔde si biribi so no so atew. Wɔ paipu ne valve ahorow ho no, trɛw ahoɔden a nsu ntumi nkɔ mu no mu na hwɛ hu sɛ wɔasɔ no koraa. Wɔ mmeae a nsu betumi akɔ so bere tenten, te sɛ nsu a wɔde gu mu no, wobetumi de nsu a ɛmma nsu ntumi nkɔ mu foforo aka board no ani nyinaa so de abɔ wɔn ho ban mprenu a nsu ntumi nkɔ mu na wɔatew asiane a ɛwɔ hɔ sɛ nsu bɛtwetwe no so bio. Ɛsɛ sɛ wɔde atɛkyɛ hyɛ skru a ɛwɔ skru no mu nso ma na wɔde atɛkyɛ hyɛ mu na ama wɔayi akwan a nsu betumi akɔ mu wɔ skru ntokuru no mu no afi hɔ.
4. Curing ne tile a wɔde si hɔ
Sɛ wɔwie nkwaa a wɔde hyɛ mu no a, ɛhia sɛ wɔde nnɔnhwerew 24–48 sa yareɛ (trɛw saa berɛ yi mu wɔ mmeaeɛ a ɛhɔ yɛ hyeɛ a ɛba fam-); ebia wobefi ase ayɛ tiling bere a ade a wɔde kata so no ayɛ yiye koraa no. Fa thin-set tiling kwan no di dwuma ne polymer tile adhesive a ɛne no hyia, fa adhesive no gu akyi board no ani tẽẽ. Wɔnkamfo nkyerɛ sɛ wɔde bed cement mortar a ɛyɛ den-si hɔ, efisɛ ɛtaa ma nsensanee a ɛyɛ tokuru (ɛnyɛ nea ɛbata ho).
Yɛ standard curing bere a tiling awie no, afei kɔ so yɛ grouting.
Mfomso a ɛtaa ba wɔ adansi mu
