Primepool

Properties

High adhesion, good workability and extended open time. Due to its composition, it has improved mechanical resistance and a finer grain size that allows grouting of joints.

Composition

Cement adhesive with mixed binders, based on cement, resins, mineral fillers and specific additives.

Support

• Plastering and cement screeds.


• Avoid direct application on plaster supports.


• For other supports, consult Primefix.

Application instructions

• Deixar repousar a massa 2 minutos antes da aplicação e de seguida efetuar uma mistura ligeira;
• Let the dough rest for 2 minutes before applying and then mix lightly;
• Apply the glue to the support in small areas, no more than 1 m2 ^to 1.5 m2 ^, using a notched trowel;
• Press and adjust the ceramic pieces to obtain continuous and complete adhesion of the glue;
• Periodic checking of the glue distribution on the part is recommended;
• In the presence of poor distribution, use the double gluing method and/or a trowel with a higher tooth;
• Limit single gluing to the maximum dimension of the pieces of 35 cm x 35 cm. Above this dimension, double gluing is recommended;
• Recommended layer thickness: 6 mm. Maximum layer thickness: 8 mm.
• Avoid placing wet items.
• Check the cleanliness of the back of the parts to be glued;
• Respect the fractionation/construction joints, using technical profiles or mastics, which allow the absorption of tensions;
• When placing ceramic tiles between 2 parallel boundaries (e.g. a corridor) there must be clearance between the end of the ceramic tiles and the obstacle or vertical slope;
• Use spacing crosspieces, at least 2 mm for small formats, gradually increasing as the size of the piece increases;
• Scrape and clean the joint before the glue hardens;
• Avoid adding product and/or water to the already mixed glue, particularly when it reaches the hardening process;
• On facades, the act of gluing/installing ceramic coating is limited to a wind speed of less than 30 km/h;
• The supporting plaster mortar must have a minimum compressive strength of Class CS IV, with adhesion ≥ 0.5 MP _A and flexural strength ≥ 2.5 MP _A. Be at least 30 days old;
• Make horizontal and vertical elastic joints in lintels, balconies and window sills. In running cloth, horizontal elastic joints every 3 m with 10 mm thickness and vertical elastic joints every 6 m with 8 mm thickness;
• When changing direction, if the pieces overlap at the corner, then leave a joint of at least 5 mm.
• In tanks and swimming pools, commissioning should only take place 21 days after gluing and grouting.

Grouting of Joints :

• You can carry out grouting after a minimum waiting period of 48 hours;
• In closed, unventilated areas and on low-absorption substrates, extend the waiting time to 72 hours. Ensure there is no moisture present.
• You can grout the joints with the Primecolour mortar most suitable for the application.
• When grouting tablets, fill them as soon as they are firm.
