APPLICATION
Stone Stop Pumice Method
Pumice stone is a natural rock that can be easily found in our country. Pumice stone, which is usually burgundy in color, is frequently preferred in dry landscaping applications. However, pumice stone has a disadvantageous structure in terms of freeze-thaw and impact resistance due to its lightness and porous structure. This porous structure also prevents Taşstop resins from fixing the pumice alone.
We cover the surfaces of pumice stones with a special resin with our “Ponza-Stop” filled resin, for which we have completed R&D studies on this subject. This resin can also be in pumice color if desired. When used at a certain rate (approximately 20% of pumice weight), all pumice aggregate surfaces can be covered with a resin mortar structure. Both the resistance of the stones against freezing and thawing increases and significant improvements are experienced in their impact strength.
Water-based TaşStop is used to fix pumice aggregates coated with Pumice-Stop. It should not be forgotten that pumice stones are inherently weak stones. For this reason, the purpose of fixing these stones to each other is to prevent the stones from being dispersed by water or wind, and to prevent the stones from being carried away by the air blower during leaf and dry garbage cleaning with air blowing. Pedestrian load will be limited due to the stone's own strength.
Step 1
Pumice aggregates that are dust-free or have very low dust content are taken to the Isopave mixer or concrete mixer. They are mixed with water until the pumice surfaces are saturated, provided that it is not too much. This process is important, otherwise the water of the coating mortar will be absorbed by the pumice and the water necessary for the strength of the mortar will be lost.
During the process, water should not be allowed to accumulate in the mixer, and the mixing process should not be done too much because the stones grind quickly. If on-site fixing is planned, the pumice stone covered surface should be both watered and mixed with a rake to ensure that the stone surfaces are wet.
Step 3
Covering the pumice surfaces on site requires professional application. For this, you will need a special spraying mortar pump. As in the previous stage, the first step will be to saturate the stone surfaces with water. Then, the prepared mortar is sprayed onto the surface and the pumice is mixed on site with a rake to ensure that the surfaces are saturated with mortar. Afterwards, it should be waited for at least three days for the drying process to be completed and for the mortar to gain its strength.
Step 2
Special TasStop pumice mortar is mixed in a separate container as 4 parts powder and 1 part liquid mixture by weight. After homogeneity is achieved in the mixing process, 20% of the pumice stones are added to the mixer by weight. After ensuring that the pumice stone surfaces are covered with mortar, the mixing process should be terminated without allowing the stones to crumble too much. Afterwards, the coated pumice stones should be left to dry for 3 days. The mixing process can be done with an Isopave mixer, low-speed mixer or concrete mixer.
Step 4
The coated pumice stones, which are completely dry, are now ready to be fixed. In fixing the pumice stone, water-based TaşStop can be applied in all 3 methods. It should not be forgotten that the least resin will be used in the mixing method.
