Stauf has added LVP-777 Pro-Lux, a specially formulated adhesive for the installation of luxury vinyl tiles and planks. With this formulation, installers will find that it is easier to spread and can be used either as a wet lay adhesive, or installers can wait 30 to 40 minutes to use it as a pressure-sensitive adhesive, according to the company. LVP-777 is formulated to decrease shrinkage, increase green grab, and reduce cupping and end peaking due to its extremely high shear strength.
Stauf Adhesives has purchased Advanced Adhesives Technologies, a Georgia-based flooring adhesive manufacturer. The two companies will continue to operate as separate entities, and there will be no changes in current distribution, employees, or management.
Apply adhesive to sub floor using the appropriate STAUF notched trowel, avoid adhesive pooling and excessive layer thickness by evenly raking the notched trowel over adhesive layer. Install wood flooring during specified open time, slide in and press down firmly. In particular with raw wood flooring, avoided pushing adhesive into joints. Adhesive in joints can impair subsequent surface treatment. Depending on the degree of setting, adhesive residues can be removed with the appropriate STAUF cleaners. Please test the effect of the cleaner on the finish of the wood flooring in an inconspicuous area or on a sample prior to applying the cleaner. Hardened adhesive residues can easily be removed mechanically, mostly residuefree. However, longer exposures on finished wood flooring should be avoided to prevent possible contouring.
The adhesive hardens when reacting with moisture either in the form of air humidity, wood or substrate moisture. The higher the ambient temperature, the faster the adhesive sets. Setting time increases with thickness of the adhesive layer. Plasticizers contained in the adhesive can cause flow asphalts to partially dissolve and may affect the wood flooring finish systems, especially for wood flooring installed without tongue and groove technique. For solid floorboards and solid parquet flooring from a width thickness ratio of 1:7, for thinner solid wood formats of 1:5 (e g. 10 mm lamparquet), or for laying strongly reacting solid wood types on underfloor heating, it can be useful to bond them in a shear-resistant or hard manner.
This solvent-based flooring adhesive can be used to stick down both solid and engineered flooring on subfloors with a moisture content of less than 3.5%. The glue has a working open time of approximately 10 minutes and covers up to approx 1.1 sqm. per kg. Total coverage per tub up to 18.7 sqm. Use Trowel No.4 when fitting solids and Trowel No.5 when fitting engineered floors. Suitable for use with underfloor heating.
The preparation of the subfloor is important to ensure that it is ready for installation, ie absolutely dust-free, firm, sufficiently rough, absorbent where necessary, flat, permanently dry and without cracks. To process this, preparatory work may be necessary (sweeping, vacuuming, brushing with a brush machine, sanding or sanding, milling, shot blasting), depending on the type of subfloor and its condition. Cracks and joints, with the exception of edge expansion joints and other building construction joints, must be permanently closed with STAUF Cast resin and the associated hooks. Holes and indentations can be filled with a form-retaining leveling product from Stauf. To obtain a flat, absorbent and sufficiently rough subfloor, it may be advisable to level with a designated STAUF leveling product.Processing,
Apply the adhesive evenly with the appropriate notched trowel with prescribed serrations in a smooth motion, avoiding glue pools and excess thickness. Apply the parquet in the adhesive bed within the specified time with a short sliding movement and press the floorboard firmly. Particularly with unfinished parquet, care must be taken not to slide glue between the joints. Glue in the joints can react negatively with later finishing products Glue in the joints can react negatively with later finishing products. Adhesive residues can be removed with the appropriate STAUF stain remover, depending on the curing time. Assess the expected result in an inconspicuous place or on a leftover piece of factory-finished parquet. Cured adhesive residues can be completely removed mechanically relatively easily; it is true that too long an effect on finished parquet should be avoided in order not to get any markings.load capacity,
The adhesive hardens through a reaction with moisture. The moisture is obtained from the ambient air, the wood or the substrate. A higher ambient temperature accelerates the curing. The thicker the adhesive bed, the longer the curing time is. Plasticizers in adhesives can affect the consistency of mastic asphalt screeds. Particularly with parquet strips without a tongue-and-groove connection, there is a risk that plasticizers will damage the parquet varnish. With solid planks and solid parquet from a width-thickness ratio of 1:7, with thinner solid wood of format 1:5 (e.g. 10 mm parquet) or when laying nervous wood types on underfloor heating, it can be useful to glue with hard glue , e.g. STAUF SPU 570, STAUF PUK 446 or PUK 455, to prevent shearing.
Divergent 574 modified pressure-sensitive adhesive can be used as dry-set, wet-set or tacky-wet system, allowing the installer to use this adhesive over multiple kinds of substrates whether they be porous or non-porous. Suitable for both resilient and carpet applications as well as rubber tile and vinyl stair treads, Divergent 574 eliminates the need to stock multiple adhesives, according to Sonny Callaham, founder of Divergent Adhesives. The specially crafted, quick-drying formula boasts a high moisture tolerance of 99% RH and 12 lbs. In addition, it can offer extremely high shear and peel values that can help ensure a successful installation for your next flooring project.
Before installing the floor, the cast substrate must be carefully checked in accordance with the relevant guidelines. The substrate must be resistant to pressure and stresses, must not have any cracks, must be of sufficient surface-bonding strength, and must be permanently dry, flat, clean and free of substances that may impair the adhesive properties of the glue. In addition, the porosity and adhesiveness of the surface should also be checked as well as the moisture content, room temperature, air humidity and the temperature of the substrate. The choice of concrete type can have a strong bearing on drying times. Any moisture in the concrete could damage the wooden floor.
Floor planks must be glued where they butt up against each other at the ends, but they should never be glued lengthways! Oak planks wider than 300 mm must be laid with a 2 mm distance between all the plank rows. 59ce067264
