DCI 200 POLYMER MODIFIED
High-performance cementitious adhesive with no vertical slip for ceramic tiles and stone materials
.
Characteristics
DCI 200 is a grey or white powder composed of cement, fine-grade, synthetic resins and special admixtures. Mixed with water, DCI 200 becomes an easily trowelable mortar with good bonding strength, low slump and high grab so that it can be applied vertically without sagging, even holding heavy tiles. DCI 200 hardens without noticeable shrinkage to become extremely resistant, adhering perfectly to all the conventional materials used in construction. N.B.: Mixing DCI 200 with LATEX or ADMIX S2 in place of water improves the characteristics to meet the requirements of class C2TEES2 (improved highly deformable cementations adhesive with extended open time) according to EN 12004 and EN 12002
Recommendations for use
Use DCI 200 mixed with Latex or Admix S2 in the following cases:
- Interior aerated concrete block walls;
- Gypsum board;
- Under floor heated installations;
- Interior painted walls, as long as the paint is firmly anchored;
Do not use DCI 200 in the following cases:
- On concrete subject to high shrinkage;
- On walls or floors subject of high vibration or movement;
- On metal, rubber, PVC and linoleum surfaces;
- Where the surface must be set to light foot traffic rapidy
- For the installation of non-absorbent tiles (porcelain tiles, single-fired tiles, clinker tiles, etc.) on other non-absorbent wall and floor substrates.
Storage
DCI 200 can be stored for 12 months in a normal environment and original packaging. The product complies with the conditions of Annex XVII to Regulation (EC) N° 1907/2006 (REACH), item 47.
Application Procedure
Preparing the substrate
The substrates must be cured, mechanically strong, free from loose particles, grease , oils, paints, wax and sufficiently dry. Cement substrates must not be subject to shrinkage after the installation of the tiles. During spring and summer, renders must be cured for at least one week for every centimeter of thickness and cement screeds must be cured for at least 28 days, unless they have been made with DCI special binders for screeds such as, LEVEL S-10 or with LEVEL S-30. Gypsum substrates and anhydrite screeds must be perfectly dry (max. residual moisture (0.5%) sufficiently hard and free of dust . They must be treated with GRIP PRIMER or BETON CONTACT, while areas subject to high humidity must be treated with DCI
PRIMER TILE ADHESIVE.
Preparing the mix
DCI 200 must be mixed with clean water to obtain a homogenous paste free of lumps; after 5-10 minutes resting, it must be re-mixed. The paste is then ready for use. The quantity of water to be used is ca. 25-27 parts per 100 parts (by weight) of DCI 200 (equal to ca. 6.25 - 6.75 liters of water for 25 kg of powder). The mix, produced in this
way, is workable for at least 4 hours.
Applying the mix
DCI 200 is applied with a notched trowel onto the substrate. Choose a trowel that will give coverage to the back of the tiles of at least 65-70% for walls or for indoor light foot traffic. For heavy traffic the coverage must be 100%. To obtain good adhesion to the substrate the following system is recommended: first apply a thin coat of DCI 200 using the smooth side of the trowel and immediately after
apply the desired thickness of DCI 200 using the toothed
side of the trowel.
