Tip 1: How to fix the mounting foam
Anyone who has ever had to do repairs or build on his own, knows firsthand that during the execution of these works, it is often necessary to use a mounting foam.
You will need
- - a sponge;
- - water;
- - balloon with mounting foam;
- - solvent;
- - knife;
- - gypsum or cement mortar.
Instructions
1
Before applying froth on the surface, thoroughly clean the latter from dust, dirt and other contaminants. With most surfaces, the foam forms a good grip: silicone and polyethylene are the exception.
2
Before as froth Be sure to shake well: at least do it twenty times. Moisten the contact surface with plenty of water. Then remove the protective cover from the cylinder and screw the adapter with the nozzle to the stop. Then turn the balloon upside down and start blowing the foam with a foam (fill only 2/3 of the hole, as the foam, after a little standing, starts to increase in volume).
3
Remove the nozzle from the cylinder and rinse it with a solvent, and then rinse with water.
4
After the foam dries (it can dry up from two to twenty-four hours), cut off the excess hardened pieces carefully with a knife, and remove them with the kneader - remove with a solvent.
5
On the dry froth apply gypsum or cement mortar (fill all the slots well and carefully cover with this mortar froth, because under the influence of ultraviolet rays, foam is destroyed). However, before proceeding with this procedure, cleanse froth from dust and lightly moisten with water.
Tip 2: Where can I use the mounting foam
Mounting foam - foam polyurethane sealant - a relatively new product in the construction market. The scope of application is extensive - it acts as a warming, insulating and bonding agent.
Instructions
1
A single-component MP has the following properties: fasten individual parts of structures; thicken; isolate; warm. Quality foam should stick to the surface, but do not drain, be elastic, do not shrink, do not crumble after hardening. It happens: pistol (professional), household, winter, summer, all-weather, heat-resistant. MT replaced the traditional heat-insulating and sealing materials: a patch, bitumen, a band of mineral wool.
2
Mounting foam is used in constructionobjects, repair of domestic and industrial buildings. It is widely used to seal joints between structural parts, when sealing cracks and cracks, inter-panel joints, filling voids near window and door openings. On the foam "put" door and window boxes, while not requiring additional fixation with nails or screws. With this universal material, it is possible to securely glue a heater, for example a foam board, to a wall. A different means for sealing the junctions of plumbing installations, ventilation and extracts.
3
MP is used to remove defects (cracks) inroofing materials, as well as zapenivayut gaps on floating equipment - rafts, boats. The advantage of foam is also that it is convenient to seal the cavities of any configuration, it is designed to work with many materials: wood, concrete, foam and cinder blocks, glass, metal, bricks. Does not interact with Teflon, polypropylene, silicone, polyethylene. Foam is well plastered and sealed with putty.
4
Heat-resistant foam fills the openings betweena ceiling plate and a chimney, use it when installing fire doors, doors. The winter composition is warmed by communications - pipes and hoses located outside of warm rooms. It is not recommended to use a mounting foam as a seal between the crowns of the frame. It has shrinkage, is not elastic enough, the seams need to be sealed.
5
Zapenivat emptiness must be at 1/3 of the depth,the foam expands and fills the whole space. For narrow slots, use MP with a small extension. The expiry date is of no small importance, the overdue product does not possess the declared properties. After solidification, the foam requires treatment. Surplus cut with a knife, the surface is sealed with a mounting tape and painted over or plastered.
Tip 3: How to fix slopes on the doors
Replacement of both internal and external doorsalso involves the replacement of the box. When dismantling an old box, slopes of doors often need to be closed, which are necessary, since they spoil the appearance of the room as a whole, and also have the property to collapse faster than whole slopes. You can repair the doorways yourself.
You will need
- - knife (can be clerical);
- - primer;
- - brush for priming;
- - metal corner;
- - putty or sand-cement mortar;
- - putty knife.
Instructions
1
Cut off from the demanding closure of the doorway whenhelp the knife surplus the mounting foam, probably left after installing the doors. Remove dirt from the doorway, dirt, dust, small rubbish, lime or old paint, as their particles will prevent good adhesion of the mortar and the base surface of the slope of the door.
2
Thoroughly treat with a deep primerpenetration of a slope requiring repair. This simple action will make the adhesion between the main surface and the filler solution more robust, reliable and durable.
3
Use a spatula and mortar tozashpatlevat slope and give it a flat shape. If you think it is advisable, that is, if a given slope strongly protrudes or is heavily loaded due to the location, then it will be superfluous to mount a special metal corner into it. This at times will strengthen the design of the slope and help make it as smooth as possible.
4
After the putty thoroughly dries, treat the whole surface again with a primer.
5
After that, the doorway can be whitewashed or painted, either wallpapered or wallpapered in another way, depending on where your door is located and how the interior is made in this room.
