RapideProfessional Mortar & Grouting Gun Set | 470mm Brick Pointing and Tile Cement Applicator Caulking | Roughneck Seal Building Industry DIY Tool

Great item very sturdy

Absolutely useless plunger to small let’s all grout etc squirt back up the tube nearly three quarters

Not good did not do it job, blocked when I used it.

Crap. Do not purchase. As someone previously mentioned the grout goes up the tube it isn’t pushed out. It is sturdy and quality seems good - which is useless if it doesn’t do what is intended!!

Essential tool for re-pointing. The key to success is the correct mortar mix. Typically; 5 parts builders sand, 1 part cement and 1 part lime for the dry mix. The water must have plasticiser added, the manufacturers guide lines must be followed. The one I use has a ratio of 10ml to 15ml of add-mix per 1.5 litres of water. Mix it to the consistency of hummus. Half a builder's bucket of mortar is enough material if you're working alone. If it falls out of the tube nozzle it's too wet, if it doesn't pump its too dry. Before you mix the mortar prepare the area of work. Take out the old joints with an appropriate tool, the Irwin 4 cutter mortar rake on an angle grinder makes the job easy. Goggles, gloves and ear defenders needed. Remove the joints from about 40 or 50 bricks at a time, working from top to bottom ensuring all the old mortar is removed. Brush out remaining loose fragments first, then wash away any dust from the joints with water before filling with mortar. A pointing trowel is necessary to fill low points and finish off the joint. Other tools are available. If the gun jams up, don't force it out, tip the contents back into the bucket and add a little more water to the mix and freshen it up with your bucket trowel. This gun works best pointing down, not inverted. Once you think the mortar in the joints has gone off, use a stiff hand brush to clean off excess mortar from the brickwork. Clean all residual mortar from your tools before continuing with further work. If you're working off the ground, a suitable safety structure is essential. This information is not finite, there are many variations of this process. Consult a professional if at all unsure.
