Hydro Clean HT-400 Concentrate Excess Mortar Remover

Hydro Clean HT-400 SUPER CONCENTRATE EXCESS MORTAR REMOVER as the name implies is a concentrated blend of ionic and nonionic acids that has been formulated to remove the heaviest build up of mortar smears and construction dirt from new masonry. It can be used with a spray application and high pressure water rinse or with a brush application and a water hose rinse. HT-400 is suitable for removing excess mortar from brick, concrete block, granite, sandstone and slate. It may not be suitable for certain polished brick or polished granites. It is a different formulation than our HT-455 EXCESS MORTAR REMOVER and should not be used the same as HT-455. Please review the application instructions outlined below and always perform test samples. HT-400, used as directed, is a safe product for cleaning new masonry. Questions about Hydro Clean HT-400?

It is important to protect all adjacent metal and painted surfaces while performing any cleaning operation with HT-400 SUPER CONCENTRATE EXCESS MORTAR REMOVER. Always perform a test patch cleaning area (minimum 5 ft by 5 ft area )to determine the proper dilution of HT-400 and any reactivity with adjacent substrates. Allow the test area to thoroughly dry and observe the cleaning results.

Dilutions: For most brick, granite and concrete surfaces, HT-400 can be cut with 6 to 8 parts water. For glazed brick, granite or concrete you should cut HT-400 with 8 to 12 parts water. Testing will determine the proper dilution. Also see the data sheet on our HT-455 EXCESS MORTAR REMOVER.

Application: Thoroughly prewet the surface prior to the application of HT-400. This product can be applied by brush or low pressure spray (50 psi). If agitation is necessary, use a mason’s brush or a piece of brick.. After 3 to 5 minutes, rinse using a clean brush and water or a hose. Production can be increased by using a high pressure wash of 500 to 1800 psi @ 4 to 5 g.p.m. Make sure that the stone is thoroughly rinsed. If necessary, repeat the entire procedure. Keep any wall areas wet under the area currently being cleaned. Do Not allow HT-400 to dry on the surface of the substrate being cleaned or there may be a chance of streaking. If streaking does occur, contact your local Hydroclean distributor.

HT-400 will not harm glass and special masking is not required. While it probably will not damage sound paint, a small patch test on any surface with which the product is likely to come in contact is recommended. Protect all adjacent limestone and marble surfaces. Normal precautions should be taken to prevent the product from being sprayed directly on painted or other surfaces not being cleaned. However, all adjacent metal surfaces and vegetation must be protected. Because HYDROCLEAN’S HT-400 SUPER CONCENTRATE EXCESS MORTAR REMOVER will clean other types of materials, adjacent areas which are not to be cleaned should be protected to prevent “clean spots”.
