Preparation of the surface: The surface to be coated with MAXQUCK ROLL must be perfectly clean and free from grease, oils, fungus, paints or algae. Also the substrate must structurally sound. Areas or loose elements must be eliminated mechanically or by sandblasting. Before applying MAXQUICK ROLL, a final washing of the substrate will be done to eliminate dust and dirt and to dampen it, nonetheless in the moment of application no water should remain on the surface.

Any cracks, honeycombs, defects or damages of the substrate repair using MAXREST, MAXRITE, MAXRITE 500 or 700, or MAXPLUG.

Mixing

MAXQUICK ROLL is mixed only with clean water, requiring between 24% and 28% by weight of the product, depending on the ambient conditions. The average amount recommended is about 25%, which is equivalent to 6.25 litres of water per 25 kg of MAXQUICK ROLL. The amount of mixing water should remain constant to prevent problems of different shades in the coating.

Mixing can be done mechanically or by hand. For manual mixing, add part of the water to the powder and mix with the trowel until obtaining a lump free, homogeneous mixture. Allow it to rest for about 10 minutes and mix again adding the rest of the water if necessary until obtaining the proper consistency. When mixing by mechanical means, add gradually the powder to the water and mix with a low speed mixer (400 – 600 r.p.m) until obtaining a lump free, homogeneous mix. Allow the mix to rest for two minutes, after which application can begin.

Application

During the application, the substrate must be and kept damp.

A dry substrate causes the premature loss of the mixing water for the MAXQUICK ROLL without the setting having taken place.

The application can be done using a fine haired brush, roller or mortar spraying machine. A single coat is applied ensure to cover the surface completely. In case a second coat is needed, it can be applied between 12 to 24 hours after the application of the first one.

Tools are cleaned with water immediately after the application.

Precautions during application and curing

If ambient conditions of temperatures above 25ºC, dryness or wind are present, some precautions during the first 6 hours should be taken to favour the curing, such as protection against the wind. It is also advisable to lightly spray the surface with water, taking care to do it in an even and careful way to avoid creating any colour difference.

Avoid also applications in areas exposed directly to the sun, because any shade on the surface may cause colour difference.

Do not apply if rain is expected in the following 4 to 6 hours after the application.

Do not apply at temperatures below 5 ºC or if there is risk of the temperatue dropping below this temperature in the following 24 hours.
