To guarantee that Planigrout 300 bonds well to the substrate, special care must be taken in the preparation of the surfaces to be bonded.
The concrete, natural stone or brick substrate must be clean, dry and sturdy.
The most suitable methods for preparing the substrate are chiselling, sand-blasting, milling, shot blasting, grinding or sandpapering the surface in order to remove irregular or loose parts, efflorescence, cement laitance, traces of oil and form release agents.
Then remove all traces of dust from the substrate with compressed air and/or an industrial vacuum cleaner.
Metallic surfaces must be free of all traces of rust, paint and oil preferably by means of sandblasting down to bare metal (SA 2½).
Structures made on-site in cast concrete, have to be cured for at least 4 weeks before applying Planigrout 300 to avoid the stresses induced by hydrometric shrinkage in the concrete being concentrated at the interface of the joined parts.
The three components which make up Planigrout 300 have to be mixed together. Pour component B into component A, making sure that the container with the catalyst (component B) is completely emptied, and mix them together with a drill fitted with a low-speed mixer until a completely homogeneous paste is formed. At this point, pour in the selected aggregates (component C) with a continuous, regular flow, and mix together for 4 or 5 minutes until a uniformly wet paste with a homogenous colour is obtained. The packages are already pre-dosed. Therefore, avoid using only partial quantities of the packages to avoid accidental errors in the mix ratio, which would lead to a lack or only partial setting of Planigrout 300. If the packages are to be partially used, make use of a precision electronic scale.
Planigrout 300 must be applied by pouring and, where necessary, into sealed formworks.
In order to achieve good bonding, it is advisable to pre-treat the surfaces to be repaired with Primer MF.
